Understanding HVAC systems is essential for its proper maintenance. Quarterly maintenance of your HVAC systems is important to extend the system’s lifespan and save hundreds of dollars on unexpected repairs. Regular maintenance of residential HVAC systems is essential when it comes not only to the proper function of boilers, furnaces, and AC units but also for better energy efficiency and in-home air quality. A properly maintained HVAC system can cut hydro costs from five to ten percent, as well as improving comfort and air quality.

Design of air conditioning and ventilation system for a multi storey office b...eSAT Journals
Abstract This project consists of how the proposed centralized air conditioning and mechanical ventilation system is designed and its criterion for a new building in Hyderabad. It consists of seven floors and two basements having an area of 39000sft per floor. The two basement (lower and upper) and major part of ground floor shall be meant for offices with a total area of 273000sft. The main objective is to create a thermally controlled environment within the space of a building envelope such as office space, BMS room, society room, entrance lobby etc. and building mechanical ventilation namely basement ventilation, staircase pressurisation, lift well pressurisation, toilet exhaust etc. Design and planning of the above system shall meet the required below customer objectives, like econoical in cost,energy efficient,simple and flexible with respect to operation and maintenance. The tentative air conditioning load for the system shall be 800TR apprix. Air cooled screw chillers with secondary variable pumping system are proposed to make the system energy efficient. The proposed air conditioning plant shall be located on the sw side on the building terrace. keywords: chillers, variable air volume, air handling unit

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. VENTILATING
-the process of "changing" or replacing air in any
space to provide high indoor air quality (i.e. to
control temperature, replenish oxygen, or remove
moisture, odors, smoke, heat, dust, airborne
bacteria, and carbon dioxide).
3. VENTILATION
-the intentional movement of air from outside a building to the
inside.
-includes both the exchange of air to the outside as well as circulation
of air within the building.
-one of the most important factors for maintaining acceptable indoor
air quality in buildings
4. METHODS OF
VENTILATING A BUILDING
1. Mechanical or Forced Ventilation-is used to control
indoor air quality. Excess humidity, odors, and
contaminants can often be controlled via dilution or
replacement with outside air. However, in humid climates
much energy is required to remove excess moisture from
ventilation air.
5. METHODS OF
VENTILATING A BUILDING
Kitchens and bathrooms typically have mechanical exhaust to control
odors and sometimes humidity. Kitchens have additional problems to deal
with such as smoke and grease . Factors in the design of such systems
include the flow rate (which is a function of the fan speed and exhaust
vent size) and noise level. If ducting for the fans traverse unheated space
(e.g., an attic), the ducting should be insulated as well to prevent
condensation on the ducting. Direct drive fans are available for many
applications, and can reduce maintenance needs.
6. METHODS OF
VENTILATING A BUILDING
Ceiling fans and table/floor fans circulate air within a room for the
purpose of reducing the perceived temperature because of
evaporation of perspiration on the skin of the occupants. Because hot
air rises, ceiling fans may be used to keep a room warmer in the
winter by circulating the warm stratified air from the ceiling to the
floor. Ceiling fans do not provide ventilation as defined as the
introduction of outside air.
7. METHODS OF
VENTILATING A BUILDING
2. Natural Ventilation- is the ventilation of a building with outside air
without the use of a fan or other mechanical system. It can be achieved
with open windows or trickle vents when the spaces to ventilate are small
and the architecture permits. In more complex systems warm air in the
building can be allowed to rise and flow out upper openings to the outside
(stack effect) thus forcing cool outside air to be drawn into the building
naturally through openings in the lower areas.
8. METHODS OF
VENTILATING A BUILDING
These systems use very little energy but care must be taken to ensure the
occupants' comfort. In warm or humid months, in many climates,
maintaining thermal comfort solely via natural ventilation may not be
possible so conventional air conditioning systems are used as backups.
Air-side economizers perform the same function as natural ventilation,
but use mechanical systems' fans, ducts, dampers, and control systems to
introduce and distribute cool outdoor air when appropriate.
9. TYPES OF VENTILATION
1. Mechanical or Forced Ventilation-through an air handling unit
or direct injection to a space by a fan. A local exhaust fan can
enhance infiltration or natural ventilation, thus increasing the
ventilation air flow rate.
10. TYPES OF VENTILATION
2. Natural Ventilation-occurs when the air in a space is changed
with outdoor air without the use of mechanical systems, such as a fan.
Most often natural ventilation is assured through operable windows
but it can also be achieved through temperature and pressure
differences between spaces.
11.
12. TYPES OF VENTILATION
3. Mixed Mode Ventilation or Hybrid Ventilation- utilizes both
mechanical and natural ventilation processes. The mechanical and
natural components may be used in conjunction with each other or
separately at different times of day. The natural component,
sometimes subject to unpredictable external weather conditions may
not always be adequate to ventilate the desired space. The mechanical
component is then used to increase the overall ventilation rate so that
the desired internal conditions are met.

14. TYPES OF VENTILATION
4. Infiltration-is separate from ventilation, but is often used to provide
ventilation air.
