Description
Technical Field
The utility model relates to a heat supply and air conditioner field technical field, concretely relates to water source heat pump device.
Background
Since the last 70 s, the heat pump industry has been rapidly developed, and new technologies and methods of heat pumps are continuously abundant, so that the heat pump is widely applied to the air-conditioning and industrial fields, and plays an important role in energy conservation and environmental protection. The water source heat pump overcomes the defect that an outdoor heat exchanger of an air source heat pump frosts in winter, is reliable in operation and high in heating efficiency, and is widely applied in China in recent years. However, the surface water source heat pump is easily affected by the quality of the surface water and the temperature of the water source, and particularly, the evaporator of the water source heat pump is frozen due to the excessively low water temperature, so that the water source heat pump is difficult to continue to work. For example, in coastal areas in northern China, the application of seawater source heat pumps is technically difficult due to the fact that the temperature of seawater is too low in winter. The same problem exists in some water systems in Yangtze river and yellow river basin. Therefore, surface water source heat pumps are rarely used in those areas where the winter water source is susceptible to freezing. Many of the water in these areas, however, is not totally frozen and often does not freeze beneath the ice cover. Research shows that the latent heat released when low-temperature water is solidified can be more than 10 times more than the sensible heat released by water conventionally flowing through a water source heat pump evaporator under the condition of the same water amount. The existing water source heat pump cannot use the low-temperature water close to the freezing point, so that the phase change latent heat released by the low-temperature water in the freezing process cannot be reasonably utilized, and the utilization rate of the low-temperature water resource is low.
The existing heat pump device utilizing latent heat of water. When the electric heating ice melting mode is adopted, heating and refrigerating circulation needs to be stopped, energy is not saved due to the need of inputting electric energy, and overheating and fire ignition can be caused. When the hot gas bypass and the four-way valve are adopted for reverse ice melting, the condenser does not supply heat any more, and the phenomenon of liquid impact of the compressor is easily caused. Mechanical deicing, such as the spinning of an ice blade, is also often accomplished by external input of mechanical work, and the heating cycle also needs to be stopped.
In order to solve the technical problem of ice melting of a water source heat pump device capable of utilizing latent heat of water body solidification, a heating device and a heat pump capable of absorbing latent heat for heating are disclosed in the prior patent document CNIO 8518718A. The heating device is provided with a plurality of surface evaporators which directly contact with a water source for heat exchange, a condensing heat exchanger for condensation, a plurality of external surface evaporators with inlet electronic expansion valves and outlet electromagnetic valves, and a plurality of external surface evaporators which are connected in parallel and are respectively connected with the condensing heat exchanger by refrigerant pipelines; when one of the surface type evaporators needs to melt ice and remove ice, the refrigerant after condensation and heat release is accumulated in the heat exchange unit body, and is pressurized and heated to release heat and melt ice. The specific process is that an outlet valve of the evaporation heat exchanger needing ice melting and deicing is closed, refrigerant enters the evaporation heat exchanger to increase the temperature and pressure of the refrigerant to melt ice, other evaporation heat exchangers keep normal evaporation and heat absorption, and other condensation heat exchangers keep a stable condensation heat exchange state. When the ice melting and deicing of the evaporation heat exchanger are finished, the evaporation state of absorbing latent heat can be converted back by opening the outlet valve of the evaporation heat exchanger. When the evaporators melt ice one by one in turn in the mode, the whole heat pump heating device can continuously heat.
The solution provided by the above patent document, although it can solve the technical problem of self-melting ice, still has the following technical problems:
(1) the evaporator is used for directly making water into ice, the latent heat of solidification in the water is extracted, the evaporator is easy to block, the water quality selectivity is low, and the reliability is low.
(2) The system can only be arranged by water source, and the ice melting is difficult to realize when the tail end is distributed heat pump users or the heat pump users are far away from the water source.
(3) The ice melting is carried out by shunting the refrigerant, so that the operation condition of the unit is unstable. The normal work of other evaporators is influenced, and the heating effect of the user side is further influenced.
