River source / lake source heat pump, due to the designer's lack of understanding of the equipment and water quality, often in accordance with conventional design for the cyclone sanding plus other water treatment, often leading to equipment blockage. The main source of water lake source of algae, but also relatively small, do not look carefully not see some, the density is relatively small, with the water flow, cyclone sand separator for the separation of sand and other solid particles of high density, Because of the high density, centrifugal force is larger when entering the cyclone desander. It is easy to descend to the bottom of the desander with swirling, while algae etc. have low density and are difficult to rotate with the flow of water Remove with a cyclone desander. Fellock recommends that the principles of water treatment for such heat pump systems are: 1. To strengthen the pump suction inlet, which is the treatment of water absorption, can be used to fence, construction of reservoirs, coarse and fine multi-channel filter intercept, etc., from the source to reduce Into the system of impurities. 2, using shallow quartz sand filter, the depth of water treatment. Through these two measures can basically reach the use. Another board for the problem, and some design plus plate change is to prevent water damage to the heat exchanger, this can be determined according to the water quality is necessary, plus plate due to the existence of temperature, will affect the extraction of energy, affecting the use of refrigeration and heating effect.
