Water source heat pump unit

　　A heat pump type integral water-air or water-water air-conditioning device that uses water as a heat source to perform a cooling/heating cycle. It uses water as the heat source during heating and uses water as the exhaust heat source during cooling. Use water circulating in shared pipelines, water drawn from wells, lakes or rivers, or water circulating in underground coils as cold (heat) sources to produce cold (hot) air or cold (hot) Water equipment. Including a use-side heat exchange device, a compressor, and a heat source-side heat exchange device, with single cooling or cooling and heating functions.

　　 Advantages:

　　1. Energy saving, heat can be recovered during operation in winter.

　　2. One machine with multiple operations, stable operation.

　　3. The environmental effect is significant.

　　4. High energy efficiency ratio.

　　 Disadvantages:

　　 1. Restricted by the conditions of available water sources and restricted by the geographical structure of the water layer.

　　2. The system is prone to water leakage on the source side and the load side.

　　3. Affected by energy policies and fuel prices in different regions and countries.

　　 4. One-time investment and operating costs are relatively high.
