Residential HVAC Control Flashcard

Front

What is a thermistor?

Back

A thermistor is a type of temperature sensor that changes its resistance with temperature, commonly used in residential HVAC systems for its accuracy and reliability.

Front

What is the purpose of zoning in an HVAC system?

Back

Zoning in an HVAC system allows for independent temperature control in different areas of a home, enhancing comfort and energy efficiency.

Front

What is a ductless mini-split system?

Back

A ductless mini-split system is an HVAC system that provides heating and cooling without the need for ductwork, making it ideal for homes without existing ducts.

Front

What is the function of the condenser coil in an HVAC system?

Back

The condenser coil is responsible for removing heat from the refrigerant, allowing it to cool and condense back into a liquid.

Front

What is night setback in HVAC?

Back

Night setback is an energy efficiency strategy that involves adjusting the thermostat setting lower when the house is unoccupied to save energy.

Front

What is an RTD (Resistance Temperature Detector)?

Back

An RTD is a type of temperature sensor that measures temperature by correlating the resistance of the RTD element with temperature.

Front

What is the role of the compressor in an HVAC system?

Back

The compressor is responsible for compressing the refrigerant gas, raising its pressure and temperature before it enters the condenser.

Front

What is the evaporator coil's function in an HVAC system?

Back

The evaporator coil absorbs heat from the indoor air, allowing the refrigerant to evaporate and cool the air that is circulated in the home.

Front

What is the significance of energy efficiency in HVAC systems?

Back

Energy efficiency in HVAC systems reduces energy consumption, lowers utility bills, and minimizes environmental impact.

Front

What is demand response in HVAC?

Back

Demand response is an energy management strategy that adjusts the demand for power instead of adjusting the supply, often involving changes in HVAC operation during peak times.
