Electrical Component
a device that detects the temperature in an enclosed area and sends signals to the heating, ventilation, and air conditioning (HVAC) system to regulate the temperature
what is a thermostat?
used to measure the pressure of refrigerants inside air conditioning and refrigeration systems
what are refrigerant/manifold gauges?
what is the full term for the acronym GWP?
what is global warming potential?
acts as a heavy-duty relay, triggered by a low-voltage signal from the thermostat to open or close the high-voltage circuit
what is a contactor?
the temperature of a liquid refrigerant below its boiling point (saturation temperature) at a given pressure
what is subcool?
the atmospheric layer which is about 9–12 km (30,000–39,000 ft) above the ground
what is the stratosphere?
provides supplemental or emergency heat by warming air as it passes over hot coils
what are heat strips?
a chemical compound that cycles through the system to transfer heat, cooling a space by absorbing heat indoors and releasing it outdoors. It works by continuously changing between a liquid and a gas in a closed loop, a process that includes compression, condensation, expansion, and evaporation
what is refrigerant?
insignificant amounts of refrigerant that are released during proper service procedures, and are not considered a violation of the Clean Air Act's prohibition on venting
what is de minimus?
the "brain" of a heating, ventilation, and air conditioning system that receives signals from the thermostat and other sensors and sends instructions to components like the fan, compressor, and ignitor
what is the control board?
a hydrofluorocarbon (HFC) refrigerant used in many modern HVAC systems that replaced the ozone-depleting R-22 (Freon)
what is R-410A refrigerant?
regulations that control the production, use, and disposal of refrigerants, particularly those that deplete the ozone layer or are potent greenhouse gases
What is the clean air act?
converts standard AC power to variable-frequency DC power to control the speed of a variable-speed compressor and motor
what is an inverter board?
a lower-global-warming-potential (GWP) refrigerant blend of R-32 and R-1234yf
what is R 454B refrigerant?
