Heat pumps are cost-efficient, environment-friendly and easy to carry. Heat pump supplies hot and cold air inside an indoor space whenever needed maintaining the perfect temperature during both summer and winter.
A heat pump system is an HVAC system that can provide both heating and cooling by transferring heat from one place to another using refrigeration technology. It consists of an outdoor unit that contains a compressor, a fan, and a coil, as well as an indoor unit that contains a fan and a coil. In the winter, it extracts heat from the outdoor air and transfers it indoors to heat the space, while in the summer, it extracts heat from the indoor air and transfers it outdoors to cool the space. Heat pumps are known for their energy efficiency and versatility, making them a popular choice among homeowners.
This presentation introduces the principle of an air source heat pump, the key parts of the heat pump system and shows some examples of how heat pumps saves your money and protects the environment.
Chapter 1 introduction to refrigeration engineeringCharltonInao1
Refrigeration engineering refers to the design, installation, repair, and maintenance of refrigeration equipment used to store perishable goods at low, constant temperatures. There are several main types of refrigeration systems, including mechanical compression systems, which use electrically powered compressors to move refrigerant between high and low pressures; absorption systems, which rely on heat rather than compressors; and evaporative cooling systems, which use water evaporation to lower air temperatures. Refrigeration systems work by absorbing heat during phase changes of refrigerants to cool enclosed spaces and rejecting that heat elsewhere, helping to preserve foods longer.
This document discusses different types of air conditioning systems. It describes window air conditioners, split air conditioners, package air conditioners, year-round air conditioners, central air conditioners, air cooled systems, and water cooled systems. The key components of air conditioning systems are also identified as the compressor, fan, condenser coil, evaporator coil, distribution system, and grille.
An air conditioner works by using a refrigeration cycle that transfers heat from indoor air to the outdoors. It has four main components: compressor, condenser, expansion valve, and evaporator. The compressor compresses the refrigerant gas, which increases its temperature and pressure. The hot gas is then pumped into the condenser, where it releases heat and condenses into a liquid. The liquid refrigerant then flows through the expansion valve, where it expands and turns into a cold gas. The cold gas is then pumped into the evaporator, where it absorbs heat from the indoor air. The process repeats itself until the desired indoor temperature is reached.
The document provides information about an air conditioner presentation given by Rupesh, a student in the ME 1 (8th Sem) class with Roll No. 21760. It discusses how air conditioners work by collecting hot air, processing it using a refrigerant and coils to release cool air. It explains the components of an air conditioner including the evaporator coil, compressor, condenser coil and expansion valve. It also describes the air conditioning cycle where a refrigerant undergoes phase changes from a gas to liquid and back to a gas to absorb and release heat from the air.

Heat Recovery System in Domestic RefrigeratorIjrdt Journal
Refrigeration is a process in which work is done to move heat from one location to another. Refrigeration technology has rapidly evolved in last century from ice harvesting to temperature controlled rail cars. Most widely used current application of refrigeration is for air-conditioning of homes and public buildings. During refrigeration, heat from the refrigerant is dissipated for the successful completion of a refrigeration cycle. In normal household refrigerators, the heat from the refrigerant is removed using a condenser where the refrigerant cools and the air surrounding the condenser heats up. The strategy of how to recover the dissipated heat to develop a waste heat recovery system is relevant. The energy lost in waste heat cannot be fully recovered. However, much of the heat can be recovered and the loss can be minimized by adopting different measures. Hot air can be used for space heating, industrial drying, preheating aspirated air for oil burners, or any other application requiring warm air. The purpose of this project is to demonstrate the technical feasibility of a heat recovery system to recover waste heat from the condenser in the refrigerator and to reuse it for heating application.
The term ‘Heat Pumps’ actually refers to a group of technologies that can incorporate the HVAC (heating, ventilation, and air conditioning) devices which always provide heat energy which is then transferred from a source of heat or warmth to a destination that is called as a heat sink, effectively ‘pumping ‘warmth from one place to
The document discusses the components and working principles of an air conditioning system. It describes the main components as the compressor, condenser, expansion valve, and evaporator. It explains that the compressor works to compress refrigerant from a low temperature gas to a high pressure gas. The condenser receives the high pressure gas and converts it to a liquid by cooling it. The expansion valve regulates the liquid refrigerant and lowers its pressure before it reaches the evaporator. In the evaporator, the refrigerant absorbs heat from the air, cools the air, and evaporates back into a gas. The cycle then repeats through the compressor. While air conditioning is useful, it also has disadvantages, so the document recommends limiting its use
Explain working of various air conditioning equipmentmeet shah
This document provides an overview of air conditioning, including its main components and types. It discusses that air conditioning controls various parameters of air like temperature, moisture, and purity. It then describes the main types of air conditioning based on application, including comfort, industrial, summer-only, winter-only, and year-round. The main parts of window and split air conditioners are also outlined, such as the compressor, condenser, evaporator, and thermostat. Filters and control panels are also discussed.
Air conditioners, also known as ACs or air con, are a common sight in many households, businesses, and public spaces around the world. They are used to cool down the air and regulate the temperature and humidity levels in a room or building, making it more comfortable for people to work, sleep, or relax. But how do air conditioners actually work?
Thermodynamics is the study of heat and temperature and their relation to energy and work. It defines macroscopic variables like internal energy, entropy, and pressure that describe systems. Refrigerators, freezers, air conditioners, and evaporative coolers all use thermodynamic processes like compression, expansion, and heat transfer to remove heat from one area and release it to another area. They circulate refrigerants that change state from gas to liquid and back through cycles, absorbing heat inside and releasing it outside. This allows them to lower the temperature of the area being cooled.
The old method of residential heating and cooling involved burning expensive oil or gas in a furnace to heat air sent through ducts. However, much of the heat went up the chimney rather than heating the home. A new method called geothermal heating and cooling uses heat pumps and underground pipes (closed loops) to extract stable 55 degree energy from the earth to both heat and cool homes efficiently. Geothermal systems provide heating and cooling for around 25% of the cost of fossil fuels and require little maintenance over their 30 year lifespan.
Air Conditioning - The Complete Guide For Home Owners by HVAC.comWill Housh
HVAC.com presents a definitive guide to air conditioning - history, how does it work, major air conditioner components, explanation of the refrigeration cycle, description of the various types of air conditioners, helpful tips on buying a new air conditioning system, and a maintenance guide to keep your air conditioning system running in good condition.
The document discusses an air conditioning system. It begins by defining air conditioning and its key components and principles. It then describes the components of an air conditioner including the blower, evaporator coil, compressor, condensing coil, fan, air filter, and thermostat. It explains the refrigeration cycle and includes a diagram. It also discusses different air conditioning system types, components of central air conditioning like the air handling unit and cooling tower, and concludes with descriptions of the air distribution system components like fans, filters, ductwork, outlets, and dampers.
The document summarizes the refrigeration cycle and vapor compression refrigeration system. The refrigeration cycle involves compressing a refrigerant gas, condensing it in a condenser to release heat, expanding the liquid refrigerant which causes it to evaporate and absorb heat, and circulating the cold gas back into the refrigerator. The vapor compression system uses this cycle, with the main components being a compressor, condenser, expansion valve, and evaporator. The compressor increases the refrigerant's pressure and temperature, the condenser cools and condenses it, releasing heat, the expansion valve reduces the pressure and temperature causing evaporation, and the evaporator absorbs heat during evaporation to cool its surroundings.
Heat pumps provide an efficient way to heat homes by moving heat rather than creating it through burning fossil fuels. They work like a refrigerator in reverse to withdraw heat from outdoor air, water, or the ground. A heat pump system consists of a heat pump unit, heat source, and distribution system. Heat pumps can provide heating, hot water, and electricity through a combination with solar panels, and require less maintenance than conventional heating systems. They are a more environmentally friendly and cost-effective option for home heating.
This document provides information about heat engines and refrigerators. It discusses how heat engines convert heat into work using cyclic processes. Heat engines have a working substance, a hot reservoir to absorb heat from, and a cold reservoir to reject heat to. Only some of the absorbed heat is converted to work, with the rest rejected. Refrigerators and heat pumps operate in reverse by using work to transfer heat from a cold region to a hot region. They use phase changes in a refrigerant to absorb heat at low temperature and reject it at high temperature. The performance of refrigerators and heat pumps is measured by their coefficient of performance.
Geothermal heat pumps are an efficient alternative to traditional HVAC systems. They work by exchanging heat with the more stable underground temperatures via a buried heat exchange system, allowing them to heat and cool homes using less energy. This can reduce heating and cooling costs by 30-40% compared to HVAC. Geothermal heat pumps are also quieter, more durable, and do not emit toxic gases like traditional HVAC systems. However, some people report that the savings are not as high as expected or have issues with maintenance.
The document summarizes key aspects of HVAC systems. HVAC systems aim to provide thermal comfort and indoor air quality. They work by heating, cooling, and circulating air within buildings. Common components include furnaces, heat pumps, air ducts, and air conditioners which use refrigeration cycles to cool indoor air. Proper ventilation and maintenance of filters are important for the effective and safe operation of HVAC systems.
The document discusses heat pumps and heat engines. It explains that a heat pump uses mechanical energy to transfer heat from one place to another, with a coefficient of performance (COP) measuring its efficiency. A heat engine absorbs heat to do work on its surroundings, with its efficiency measured by how much work it produces relative to the heat absorbed. Common applications of heat pumps include heating, ventilation and air conditioning systems, while examples of heat engines are steam engines and internal combustion engines.
This project report summarizes the design of an energy efficient green building with optimized energy use. The building uses various techniques to minimize carbon consumption from electricity usage, including insulating walls and windows, using geothermal cooling systems, installing rainwater harvesting and solar photovoltaic systems. The CAD prototype shows the building layout and design criteria focus on minimizing operational carbon emissions and energy usage/waste. A key feature is the use of geothermal heating and cooling, which can reduce energy consumption by up to 72% compared to traditional systems. The report analyzes costs and energy usage of the building over its lifetime.
This document explains how air conditioners work through a simple refrigeration process using key components like the compressor, condenser, and evaporator. The refrigerant is compressed into a hot gas and moves to the condenser to dissipate heat before becoming a cool liquid and entering the evaporator. As it evaporates, it extracts heat from the surrounding air and is blown into the home by ducts. This cycling process continues automatically via the thermostat to maintain the desired indoor temperature.
Refrigeration is the process of lowering and maintaining a substance's temperature below the ambient temperature. Refrigerants are working fluids that absorb heat in the evaporator and release it in the condenser while undergoing phase changes between liquid and gas. The two main types of refrigeration systems are vapor compression, which uses mechanical energy to circulate refrigerant, and vapor absorption, which is heat-powered. Vapor compression is more common due to lower maintenance costs, while absorption systems have higher capacities and more consistent efficiency at partial loads.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

2. WHAT IS A HEAT PUMP
A heat pump is a device that can transfer
heat from one location to another, typically
from outside to inside a building, to provide
heating or cooling. Heat pumps work by
extracting heat from a low-temperature
source, such as the air, ground, or water, and
transferring it to a higher-temperature
location using a refrigerant and a
compressor.
3. HOW DOES A HEAT PUMP WORK
The heat pump absorbs heat from the outside air or ground,
depending on the type of heat pump. The heat is then compressed
and is made a high-pressure gas. As it passes through the coil, it
becomes a low-pressure gas. Then in the compressor, it increases its
temperature and pressure. Then this hot gas is passed through a
second coil, where it releases heat into the indoor air.
When it releases its heat, it condenses back into a liquid state and is
then passed through an expansion valve, which lowers its pressure and
temperature. This low-pressure, low-temperature liquid is then passed
through the first coil again, where it absorbs more heat and the cycle
repeats.
4. How Does Heat Pump
Work During Winter And
Summer
During the winter months, a heat pump extracts heat from the outside air
or ground and transfers it inside to heat a home or building. So, the inside
environment remains warm. The inside temperature stays higher than the
outside extremely cold temperature during winter.
In the summer, the heat pump can be reversed, extracting heat
from the inside and transferring it outside to cool the home or
building. During summer, it acts opposite to what it does in winter.
Instead of increasing the temperature, the heat pump decreases
the temperature and makes the inside air cool.
5. WHY HEAT PUMPS ARE
IMPORTANT
Heat pumps can provide both heating and cooling with a
single system providing long-term cost-saving service. It's
fewer mechanical parts and simple mechanic system makes
it easier to use for general people. Overall, heat pumps are an
important technology for providing comfortable, efficient,
and environmentally friendly heating and cooling solutions
for homes and buildings.
Heat pumps are an energy-efficient alternative to
traditional heating and cooling systems that use
fossil fuels like gas or oil. Because they move heat
rather than generate it, they can provide heating and
cooling with less energy consumption, which can
lead to lower utility bills and reduced carbon
emissions.
