What Is Water Source Heat Pump Units
Concepts:
Water source heat pump (WSHP) is a kind of high efficiency and energy saving air conditioning system that USES underground shallow geothermal resources (also called ground energy, including groundwater, soil or surface water, etc.), which can provide heat and refrigeration. By inputting a small amount of high grade energy (such as electric energy), the ground source heat pump achieves the transfer of heat energy from low temperature to high temperature. The geothermal energy is used as the heat source of heat pump heating in winter and the cooling source of air conditioning in summer. In other words, in winter, the geothermal energy is "extracted" and supplied to indoor heating after increasing the temperature. In summer, heat is taken out of the room and released into the earth's energy.
Working principle:
They are connected by pipes in turn to form a closed system in which the refrigerant circulates and flows in the system, constantly changing the state and exchanging energy with the outside world to achieve the purpose of refrigeration.Its main working process is as follows: the compressor inhales the low-temperature and low-pressure refrigerant vapor generated in the evaporator and maintains the low-pressure state in the evaporator, creating the condition that the refrigerant liquid in the evaporator continuously absorbs the heat of the refrigerant carrier and boils at low temperature.After the vapor is compressed, its temperature and pressure rise, creating the condition that the refrigerant is liquefied.After the high temperature and high pressure steam is discharged into the condenser, it is cooled by the cooling medium (water) under the condition that the pressure remains unchanged. It gives off heat, lowers the temperature, and further condenses into liquid, which is discharged from the condenser.When the high-pressure refrigerant liquid passes through the throttle valve, the pressure drops due to the obstruction, which leads to the gasification of part of the refrigerant liquid and absorbs the latent heat of gasification, so that its own temperature also decreases accordingly and becomes the wet vapor under low temperature and low pressure and enters into the evaporator;In the evaporator, the refrigerant liquid is vaporized by absorbing the heat of the refrigerant (water) under the condition of constant pressure (that is, making the cooling capacity), and the low-pressure and low-temperature vapor formed is then absorbed by the compressor, so as to repeat the cycle.
