STUDY OF ENERGY EFFICIENCY OF LOW-TEMPERATURE WATER-TO-WATER HEAT PUMP
Keywords:
condenser, evaporator, pressure gauge, filter, heat exchangerAbstract
Today, there is a growing trend towards the introduction of heat pumps in the heating system. Because low-grade heat can be used as a source in heat pumps, it is highly energy efficient. Therefore, it is important to calculate the efficiency of a heat pump using low-temperature heat sources and assess the feasibility of introducing a heat pump into the heating systems of the Karshi districts of Uzbekistan
