Basics of Heat Pump
Ambient air at all temperatures above “absolute Zero” has inherent heat. The technology employed in heat pumps helps in harnessing this energy for productive purposes- one key application being heating of water for residential and commercial purposes. The principle on which a heat pump works is the vapour compression cycle of refrigeration.
The heat pump captures the atmosphere by circulating the atmospheric air through an evaporator coil. The heat content in the air helps in vaporising and environmentally friendly refrigerant that is present in the evaporator. The refrigerant vapour is passed through a compressor where the refrigerant temperature is significantly raised. The hot gas is then moved around a heat exchanger through which the water is also circulated. The refrigerant undergoes a phase change and becomes a liquid. In this process the latent heat is transferred to the water and it gets heated to the desired temperature. The liquid refrigerant is passed through an expansion valve, where the pressure drops significantly and is send back to the evaporator. The cycle gets continued till the water reaches the desired temperature
Heat Pumps are designed based on the applications and the specific needs of the customers. Our heat pumps can be fitted for applications like residential usage where the demand can be in the range of 100 litres per day to large hostels where the demand of water can exceed 20,000 litres/day. In residential applications, our machines have a self-contained tank and hence it eliminates the need of external storage. For commercial applications, the hot water generated by the heat pump is stored in insulated storage tanks. The key to designing an efficient system is to arrive at a balance between the storage capacity and the regeneration capacity of the Heat pump.
Our range of Commercial Heat pumps range from capacities of 180 litres/hour to 1000 litres/hour. Based on the storage capacity, these machines can cater to varying demands of hot water consumption. The advantage of our Heat pumps are that they can be installed in a modular fashion thereby providing the flexibility to meet any capacity additions that are being planned by customers at later stages. To derive full efficiency of the Heat pumps, it is essential to have robust storage tanks. We also helps customers choose the appropriate insulated storage tanks
