Ever wondered about the air washer in your heating and cooling setup? In this journey, we’re exploring air washers, how they work, and how they’re making your indoor spaces a healthier and cozier place. Let’s dive into the basics of this essential HVAC component.
Duct cleaning, an essential task for keeping our homes healthy, involves carefully removing dust and dirt from the hidden passages that carry air around our houses.
Mold and mould are both acceptable alternate spellings for the same word, but mould is more frequently used in Britain. Both terms can refer to a fuzzy fungal hyphal growth or soft, and loose dirt. We can also refer to them as hollow containers to give shape, or a unique appearance, form, or personality.

Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

What Is Heating, Ventilation And Air Conditioning
System – Professional Guide
mmihomeimprovement.com/2022/09/21/what-is-heating-ventilation-and-air-conditioning-system-professional-
guide
The term “HVAC” refers to the use of numerous technologies to control the temperature,
humidity, and air quality in a closed room. Its goal is to provide a comfortable
temperature and indoor air quality. Mechanical engineering’s subfield of HVAC system
design works on the laws of thermodynamics, fluid mechanics, and heat transport.
Sometimes, experts add the field’s acronym for “refrigeration” as HVAC & R or HVACR.
Sometimes, they may also eliminate “ventilation” as in HACR (as in the designation of
HACR-rated circuit breakers).
HVAC: A Complete Breakdown
The HVAC system plays an important role In residential structures like single-family
homes, apartment complexes, hotels, and senior living facilities. Many medium to large
industries also have HVAC systems. It also plays a major role in the ventilation system of
office buildings like skyscrapers and hospitals. Transportation vehicles like cars, trains,
airplanes, ships, and submarines also have HVAC systems. Moreover, we can also see
HVAC in marine environments where we need to maintain safe and healthy building
conditions with respect to temperature and humidity using outside air.
Learn more about the Types Of Insulation For Ductwork.
Heating
Appliances that provide heat, or warmth, for the building are heaters. Central heating is a
viable option for this. A boiler, furnace, or heat pump is part of this system, which heats
water, steam, or air in a central place like a home’s furnace room or a large building’s
mechanical room.
Radiation, conduction, or convection are all possible methods of transferring heat. People
use Single-unit space heaters exclusively to heat individual rooms.
Ventilation
To create high indoor air quality, air must be exchanged or replaced in any location. It
involves controlling temperature, refilling oxygen, and eliminating moisture, odors,
smoke, heat, dust, airborne bacteria, carbon dioxide, and other gasses. This is known as
ventilation (the “V” in HVAC). Through the supply of outside air, circulation of the
internal building air, and prevention of interior air stagnation, ventilation removes
undesirable odors and excessive moisture. Mechanical and natural ventilation techniques
are the two categories of ventilation we mainly use in buildings.
2. 2/5
Air Conditioning
One can lower the temperature of All or a portion of a building. Additionally, one can also
control its humidity by employing an air conditioning system or freestanding air
conditioner. Due to the fact that open windows would interfere with the system designed
to maintain constant indoor air conditions, air-conditioned buildings frequently feature
sealed windows. Typically, a vent from outside draws new air into the system, where it is
mixed with return air from space. The air is then routed to a part of an indoor or outdoor
heat exchanger where it is to be cooled before establishing positive air pressure in the
room. The opening of this vent can typically be changed to change the proportion of fresh
air in the return air.
10% of the supply air typically consists of fresh air. By removing heat, air conditioning,
and refrigeration work. Radiation, convection, or conduction are all methods of removing
heat. Refrigerants, which include substances like water, air, ice, and chemicals, are the
heat transfer medium in a refrigeration system. We use A refrigerant in a free cooling
system that employs pumps to circulate a cool refrigerant. one can also use it in a heat
pump system that uses a compressor to drive the thermodynamic refrigeration cycle
(typically water or a glycol mix).
It is essential that the cooling area’s air conditioning horsepower be adequate.
Underpowered air conditioners will waste energy and use it inefficiently. For any installed
air conditioner, the system requires sufficient horsepower.
What Is The Energy Efficiency Of An HVAC System?
As the building sector consumes the greatest portion of global energy, HVAC plays a vital
role in boosting building energy efficiency. HVAC equipment producers have been
working to improve the efficiency of the systems they provide since the 1980s. technicians
sparked it by rising energy prices, but more recently, they increased it by growing
environmental consciousness. Additionally, you can also elevate tenant productivity and
wellness by making HVAC system efficiency improvements. Over time, the EPA in the US
has enforced stricter regulations. There are various ways to increase the effectiveness of
HVAC systems.
Heating Power
In the old days, water heating was the norm in the United States because it was more
effective at heating buildings. Forced air systems are more common today. Moreover, we
can also use them for air conditioning.
The advantages of forced air systems, which we frequently utilize in high-end homes,
schools, and churches, include:
1. Improved impacts of air conditioning
2. Savings in energy of up to 15-20%
3. Uniform conditioning
3. 3/5
The installation price, which can be a little more expensive than with conventional HVAC
systems, is a disadvantage. By using zonal heating, central heating systems’ energy
efficiency can be increased even further. This enables the application of heat more
precisely, much like non-central heating systems. There are several thermostats that
control the zones. Thermostats in water heating systems control Zone valves.
They operate zone dampers located inside the vents of forced air systems, which
judiciously impede the airflow. In this instance, keeping a proper temperature depends
heavily on the control system. You can also determine the Supply for the demand for
heating energy to the building in each unit of time by forecasting. It is another approach
to managing building heating.
Heat Pump With A Ground Source
Similar to regular heat pumps, ground source or geothermal heat pumps use the constant,
even temperature of the soil to provide heating and cooling instead of transporting heat to
or from the outside air. Seasonal temperature extremes are common in many places,
necessitating the use of large-capacity heating and cooling systems to heat or cool
structures.
For instance, a conventional heat pump system would use a lot of energy to cool a
building in Death Valley, California, in 1913, where the temperature was 57 °C (134 °F),
the highest temperature ever in the US, or to heat a building in Montana, where the
temperature was 57 °C (70 °F) below zero. But the temperature of the ground doesn’t
change much below a meter below the surface of the planet. It is frequently possible to
drastically reduce the capacity of a heating or cooling system by using this vast source of
somewhat moderately heated earth. 1.8 meters (6 feet) deep, temperatures typically only
range from 7 to 24 °C (45 to 75 °F), despite the fact that ground temperatures vary
depending on latitude.

Solar-Powered Cooling
Solar photovoltaic panels present a novel technique to perhaps lower the cost of air
conditioning operation. Any direct-current solar power must be inverted in order to work
with conventional air conditioners because they operate on alternating currents. Since
this conversion is unneeded and the motors are tolerant of voltage changes associated
with variations in provided solar power, new variable-speed DC-motor units make it
easier to operate solar power (e.g., due to cloud cover).
Recovery Of Ventilation Energy
In order to recover sensible or latent heat from exhausted air, energy recovery systems
occasionally use heat recovery ventilation or energy recovery ventilation systems that use
heat exchangers or enthalpy wheels. One can do this by transferring energy from the stale
4. 4/5
indoor air to the entering fresh outdoor air.
Energy Used By Air Conditioning
Thermodynamics sets a limit on the efficiency of vapor compression refrigeration cycles.
Thermal efficiencies do not accurately characterize the performance of these air
conditioning and heat pump systems since they transport heat rather than change its
form.
Performance is measured using the Coefficient of Performance (COP), but this
dimensionless metric is not widely used. Instead, the performance of many HVAC
systems has typically been described using the Energy Efficiency Ratio (EER). The Energy
Efficiency Ratio (EER) is calculated using an outdoor temperature of 35 °C (95 °F).
The Seasonal Energy Efficiency Ratio (SEER), also known as the ESEER in Europe, is a
modified version of the EER that is intended to more properly reflect the performance of
air conditioning equipment over a typical cooling season. Instead of using a constant
outdoor temperature of 35 °C (95 °F), SEER ratings are based on seasonal temperature
averages. The current minimum SEER rating for the industry is 14 SEER. Engineers have
identified a few places where they can increase the effectiveness of the current hardware.
For instance, the air-moving fan blades are often stamped from sheet metal, which is a
cost-effective manufacturing process. However, it also results in less aerodynamic
efficiency. The amount of electrical power needed to move the air might be cut in half with
a well-designed blade.
Demand-Controlled Ventilation For Kitchens
Demand-controlled kitchen ventilation (DCKV) is a building control strategy for adjusting
the volume of supply. It also exhausts air in a commercial kitchen in response to the
actual cooking loads. With the use of DCKV technology, traditional commercial kitchen
ventilation systems that work at 100% fan speed regardless of the amount of cooking
activity can save a lot of money on conditioned air and fan energy. A person can also use
Smart sensing technology to control the exhaust and supply fans in order to take
advantage of the affinity laws for motor energy savings. This technology may also save
money on makeup, air heating, and cooling, improve safety, and lower background
kitchen noise levels.
What Is An HVAC Specialist?
A tradesperson with expertise in refrigeration, heating, ventilation, and air conditioning is
an HVAC technician. In the US, HVAC technicians can acquire training from accredited
universities; most of them award associate degrees. Training for HVAC technicians
comprises both classroom instruction and practical practice. Many people can go further
by an apprenticeship in which a recent graduate spends some time working with an
experienced HVAC technician. A certified HVAC technician may specialize in things like
commercial refrigeration, heat pumps, air conditioning, and gas heating.
