Water source heat pump is an air conditioning technology that utilizes solar energy resources stored in Earth's water as cooling and heating sources for conversion. The water temperature that can be utilized by the water source heat pump unit is 12-22 ℃ in winter, and the water temperature is higher than the ambient air temperature. Therefore, the evaporation temperature of the heat pump cycle is increased, and the energy efficiency ratio is also improved. In summer, the temperature of the water body is between 18-35 ℃, which is lower than the ambient air temperature. Therefore, the condensation temperature of refrigeration decreases, making the cooling effect better than that of air-cooled and cooling tower types, thereby improving the operating efficiency of the unit. The water source heat pump consumes 1kW. h of electricity, and users can obtain 4.3-5.0kW. h of heat or 5.4-6.2kW. h of cooling capacity. Compared with air source heat pumps, their operating efficiency is 20-60% higher, and the operating cost is only 40-60% of that of ordinary central air conditioning
