2. Automatic balancing valve - Wikipedia

   en.wikipedia.org/wiki/Automatic_balancing_valve

   Although the capital costs of installing a constant flow system are relatively low, the manual balancing required is time-consuming, complicated, laborious and system is inefficient. This results in higher running costs and subsequently resulting in higher CO 2 emissions. Since most air-conditioning and water distribution systems only reach ...

3. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   In some areas electrical resistance heating is used, especially where the cost of electricity is low or the primary purpose is for air conditioning. Modern high-efficiency furnaces can be up to 98% efficient and operate without a chimney, with a typical gas furnace being about 80% efficient. [ 1 ]

4. Damper (flow) - Wikipedia

   en.wikipedia.org/wiki/Damper_(flow)

   A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control - for example, in the case of Volume Control Dampers. [1] Its operation can be manual or automatic. Manual dampers are turned by a handle on the outside of a duct.

5. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   An air conditioning system, or a standalone air conditioner, provides cooling and/or humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions.

6. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

7. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   A heating system is a mechanism for maintaining temperatures at an acceptable level; by using thermal energy within a home, office, or other dwelling. Typically, these systems are a crucial part of an HVAC (Heating, Ventilation, and Air Conditioning) system.
