Description

A water source heat pump device

technical field

The invention relates to the technical field of heating and air conditioning, in particular to a water source heat pump device.

Background technique

Since the 1970s, the heat pump industry has developed rapidly, and new technologies and methods of heat pumps have been continuously enriched. They are widely used in air conditioning and industrial fields, and play an important role in energy conservation and environmental protection. Among them, the water source heat pump overcomes the deficiencies of the frosting of the outdoor heat exchanger of the air source heat pump in winter, has reliable operation and high heating efficiency, and has been widely used in China in recent years. However, the surface water source heat pump is easily affected by the surface water quality and water source temperature. In particular, too low water temperature will cause the evaporator of the water source heat pump to freeze and it is difficult to continue to work. For example, in the coastal areas of northern China, due to the low temperature of seawater in winter, there are technical difficulties in the application of seawater water source heat pumps. Some water systems in the Yangtze and Yellow River basins also have the same problem. Therefore, surface water source heat pumps are rarely used in these areas where water sources are prone to freezing in winter. But many bodies of water in these regions aren't all frozen, and the underside of the ice sheet tends not to freeze. Studies have shown that in the case of the same amount of water, the latent heat released when low-temperature water solidifies can be as much as 10 times more than the sensible heat released by water flowing through a conventional water source heat pump evaporator. The existing water source heat pump cannot use the low-temperature water near the freezing point, and cannot reasonably utilize the latent heat of phase change released by the low-temperature water during the freezing process, resulting in a low utilization rate of low-temperature water resources.

In existing heat pump devices utilizing latent heat of water. When the electric ice melting method is adopted, the heating and refrigeration cycles need to be stopped, and energy is not saved due to the need to input electric energy, and it may also cause overheating and fire. When the hot gas bypass and the four-way valve are used for reverse ice melting, the condenser will no longer supply heat, and it is easy to cause the occurrence of liquid hammer in the compressor. When mechanical deicing is used, such as the spinning of the ice blade, it is often completed by inputting mechanical work from the outside, and the heating cycle needs to be stopped.

In order to solve the technical problem that the water source heat pump device that can utilize the latent heat of water solidification has its own melting ice, the existing patent document CNIO8518718A discloses a heating device and a heat pump capable of absorbing latent heat for heating. The disclosed heating device is provided with a plurality of surface-type evaporators that directly contact the water source for heat exchange, and a condensing heat-exchanger for condensing functions. Refrigerant pipelines are respectively set between the external surface evaporators in parallel and the condensing heat exchangers; when one of the multiple surface evaporators needs to melt or remove ice, the refrigerant after condensation and heat release is used in the heat exchanger. Accumulation in the heat unit body, pressurization and temperature rise, and exothermic melting of ice is carried out. The specific process is to close the outlet valve of the evaporative heat exchanger that needs to be melted and de-iced, and the refrigerant will enter the evaporative heat exchanger to increase its temperature and pressure to melt the ice, and the other evaporative heat exchangers maintain normal evaporation. Absorb heat, and other condensing heat exchangers maintain a stable condensing heat exchange state. When the evaporative heat exchanger is finished melting and deicing, it can switch back to the evaporative state of absorbing latent heat by opening its outlet valve. When multiple evaporators take turns to melt ice in this way, the entire heat pump heating device can continuously heat.

Although the solution provided by the above patent documents can solve the technical problem of self-melting ice, it still has the following technical problems:

(1) Using the evaporator to directly make water into ice to extract the latent heat of solidification in the water, it is easy to block the evaporator, and the water quality is not very selective and the reliability is not high.

(2) The system can only be arranged by the water source, and it is difficult to achieve ice melting when the end is a distributed heat pump user or when the heat pump user is far away from the water source.

(3) The use of refrigerant diversion to melt ice will make the operating conditions of the unit unstable. It will affect the normal operation of other evaporators, thereby affecting the heating effect on the user side.
