How A Heat Pump Works - HVAC

The video tutorial explains the components and operation of heat pump systems, focusing on both cooling and heating modes. It covers the roles of the indoor and outdoor units, the flow of refrigerant, and the function of key components like the compressor, expansion valve, and reversing valve. The tutorial also discusses how heat pumps extract energy from the air, even in cold conditions, and the impact of refrigerant boiling points on efficiency.

What are the main components of an indoor heat pump unit?

What role does the reversing valve play in a heat pump system?

How does the refrigerant flow through the heat pump system during cooling mode?

How does the temperature difference between refrigerant and outside air affect heat exchange?

Describe the process of heat exchange in the outdoor unit.

What happens to the refrigerant as it passes through the expansion valve?

Explain how the heat pump operates in heating mode.

In what conditions can a heat pump still extract energy from the air during winter?

What is the significance of the boiling point of refrigerants in heat pump operation?

What are the potential efficiency issues when operating a heat pump at low temperatures?
