Water resource heat pump unit is a kind of heat pump unit type integrated water-gas or water-water cooled central air conditioning equipment, which can carry out refrigeration/heating cycle with water as heat source. When heating, water is used as heat source and when cooling, water is used as heat source. The machine and equipment for making cold (hot) wind or cold (hot) water by using the circulating system to flow in the same pipe, the water extracted from the deep well, the lake or the river, or the water circulating in the underground fan coil; Contains an application side heating equipment, refrigeration compressor, heat source side heating equipment, with single cooling or cooling and heating. The factors that cause the efficiency of the heat pump unit is not too high are the units that are very easy to defrost or freeze in the whole process of defrosting or melting ice, and also virtually reduce its efficiency. From the principle, the efficiency of the air energy heat pump has a very large correlation with the working temperature. The higher the working temperature, the greater the heat in the air, the lower the working temperature, the less the heat in the air, which is one of the reasons why the efficiency of the unit is not too high at ultra-low temperature. Local operation standard extreme operation standard extreme key said that the water is poor, large dust. Very poor water is very easy to lead to the unit scale, endangering the actual heat transfer effect of the unit; Dust, dust will be very easy to absorb on the finned heat exchanger, resulting in gas circulation, endangering unit efficiency. Unit model selection is not scientific, it can not reach the actual effect of customer application, so it must be selected in accordance with the extreme conditions. The above is the relevant matters of the heat pump unit, looking forward to having certain assistance to you
