The replacement of a manual heating control with a conventional wax motor TRV has been estimated to save at least 280 kilograms (620 lb) of CO 2 per year (in 2011 for a British semi-detached house with 3 bedrooms and gas heating [1]). They are also considerably cost-efficient, using heat only when needed, and can reduce heating bills by up to ...
The scheme was run by the Energy Saving Trust [1] and was launched in 2000. The logo is registered with the UK Patent Office and could be used by manufacturers, retailers and suppliers to signpost consumers to best-in-class energy efficient products. The Energy Saving trust no longer awards a "Recommended" certification. Its product ...
Depiction of New York World Building fire in New York City in 1882. Building codes in the United States are a collection of regulations and laws adopted by state and local jurisdictions that set “minimum requirements for how structural systems, plumbing, heating, ventilation, and air conditioning (), natural gas systems and other aspects of residential and commercial buildings should be ...
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 ...
Energy Saving Trust was formally established in November 1992. [7] [3] It was formed, as a public-private partnership, in response both to the director-general of Ofgas's 1991 proposal to increase energy efficiency in natural gas use, [8] [9] [10] and to the global June 1992 Earth Summit call to reduce greenhouse gas emissions and prevent global warming and climate change.
Energy saving modules (ESM) reduce the electricity consumption (kWh) and maximum demand (kW) of air conditioning and refrigeration compressors. The concept was developed in Australia in 1983 by Abbotly Technologies and is now distributed by Smartcool Systems Inc. [1] The system works in conjunction with existing HVAC controls ensuring that compressors work at maximum efficiency, while ...
OpenTherm (OT) is a standard communications protocol used in central heating systems for the communication between central heating appliances and a thermostatic controllers. [1] As a standard, OpenTherm is independent of any single manufacturer. A controller from one manufacturer can in principle be used to control a boiler from another ...
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.
