Commercial and industrial Hot Water Heat Pumps are designed to offer hot water for commercial and (or) industrial application. In order to achieve the required water temperature, large heat pump units apply unique V style evaporator design, which enlarges the heat exchange surface and increases efficiency

High working pressure :

The copper pipe is of 0.8- 1.2 mm thickness, no welding inside with its extra ordinary pressure resistance property. The copper pipe is without any leakage under 5kg/sq.cm pressure test.

• Famous branded rotary compressor for domestic heat pumps.
• Copland or Donfoss scroll type compressor for commercial and industrial heat pump.
• Can work at -25deg.C, low noise, long life and long working time design.

Air source Heat pump is a device which extracts heat from air and transfer heat to the water. Main components of heat pump are

• Evaporator
• Compressor
• Condenser
• Expansion valve
• Fan

Function:

Fan draws out side ambient air in to the heat pump and pass through the evaporator coil. In the evaporator coil, the refrigerant can turn liquid to gas at very low temperature. This gas compressed by compressor to elevate the temperature and pressure. Condenser is nothing but tube in tube or tube in shell heat exchanger is made of copper pipe with no welding inside. The internal spiral surface of copper tube ensure effectiveness of heat exchanger. Provision is made for gas as well as water connection.

Heated gas pass through one tube while water passes through the shell. Water gets instantly heated from 15 deg.c to 55 deg.c. Refrigerant gas is condensed and goes to liquid from the same pressure as discharged by compressor. In expansion valve, causes sudden pressure drop in refrigerant, in turn refrigerant temperature drop to temperature below the ambient

• Electrical expansion wall(EEV) is used for domestic range.
• Alco(Emerson) or Donfoss thermal expansion wall(TEV) is used for commercial range.

Domestic Heat pump circulating model adopts high efficiency tube in shell water heat exchanger and incorporate a built in German Willo pump and for every installation. The unit is capable of producing hot water with a maximum temperature up to 55 deg.c It can retrofit to existing solar water heater tank or electrical geyser to replace electric water heater. save more than 2/3 energy.
