Maintenance of air source heat pump unit

The water or river water has high content of mud, sand, algae and other impurities. The water surface is directly in contact with the air, and the water body has high oxygen content and strong corrosivity. If the surface water is directly supplied to each heat pump unit for heat exchange, it is easy to reduce the life of the heat pump unit, and the performance of the heat exchanger is reduced due to scaling. In serious cases, it will also lead to pipe blockage. Therefore, during maintenance, The river water or tap water is separated from the circulating water of the condenser evaporator by a heat exchanger, which uses a small temperature difference heat exchange method. Set automatic backwash filter in the system and take algae-killing measures.
