Application of heat pump type cold and heat source and heat recovery system in energy-saving renovation of precision air conditioning
In response to the low utilization rate of exhaust heat in the precision air conditioning room of a certain research institute,a heat pump type cold and heat source and heat recovery system are designed and installed based on the actual application status of the fresh air unit in the air conditioning room of a certain building.Statistics on the electricity consumption before and after the installation of heat pump type cold and heat sources and heat recovery systems show that the annual operation results show that the energy-saving rate after the installation of heat pump type cold and heat sources and heat recovery systems is 41.2%,saving about 225598.85 yuan in electricity costs,and the energy-saving effect is very significant.
