Heat Pump

HOW DOES A HEAT PUMP WORK :

Major components of a heat pump water heater include a compressor, a refrigerant, two heat exchangers ( a condenser and an evaporator) and an expansion valve.

• The operation begins with air being forced through an evaporator which contains a liquid refrigerant, with the help of a fan.
• This refrigerant evaporates to a gas and extracts heat from the ambient air.
• The warm gaseous refrigerant then passes through the compressor, which increases its pressure and it becomes a hot gas.
• This hot gas enters a heat exchanger (condenser) and transfers its heat to the water flowing from a storage tank.
• The refrigerant cools down in the condenser and becomes a warm liquid.
• It then passes through an expansion valve and becomes a cool liquid and enters the evaporator again.
• The cycle is then repeated in this manner.
• Thus heat absorbed from the air is transferred to the water and the heating continues till the desired temperature is reached.
