Heat Pump is a device, which extracts heat from air and transfer heat for heating water. Main components of heat pump are:

Fan - Ambient air flows through Evaporator coil and is sucked by axial fan. Evaporator coil is protected buy filter against dust. Fan is with protection grill. Outgoing air is cooler by 3 to 50C than incoming ambient air.

Evaporator coil- It is made of copper tubes with aluminium fins. Refrigerant in liquid form flows through this coil. Refrigerant gets heat from air to be converted to gas form.

Compressor – Gas is compressed buy compressor to elevate temperature and pressure.

Condenser – It is nothing but insulated tube-to-tube heat exchanger made of copper tubes with S.S.304 casing. Provision is made for gas as well as water connections. Heated gas passes through one tube while water passes through the adjacent tube in opposite direction. Water gets instantly heated. In normal design, difference in temperature is 300C. Water gets heated from 250C to 550C.Refrigerant gas is condensed and goes to liquid form at same pressure as discharged by compressor

Expansion Valve This device causes sudden pressure drop in liquid refrigerant. In turn liquid temperature drops to temperature below that of ambient air. It is ready to receive heat from air. Thus gas cycle gets completed.
