Description
Technical field:
The utility model relates to a kind of air preheat type heat pump evaporimeter that possesses the preheated air function, is applicable to the heat pump air conditioner refrigerating field.
Background technology:
Heat pump air conditioner is a kind of effective energy-conserving product, has the characteristics of the high and low consumption of heating efficiency, energy-conservation and environmental protection, in recent years, is applied in the many areas of China.At present, the outdoor evaporimeter of heat pump air conditioner commonly used adopts the fin tube type air cooling heat exchanger mostly, and cold-producing medium flows in pipe, and air flows between fin outside pipe, and the cold and hot exchange by cold-producing medium and air realizes heating.But to its operating position investigation as can be known: heat season, under the outdoor temperature situation on the low side, the evaporating temperature of outdoor evaporimeter reduces, and causes the operation of heat pump decrease in efficiency in the winter time, and the heating effect of heat pump is not very good yet.In addition, low excessively outdoor temperature also causes evaporimeter frosting easily, and when the cross valve reverse cycle defrost, the operation of heat pump mode transfers refrigeration modes to, not only influences indoor comfort and has also increased energy consumption.
Summary of the invention:
In order to solve existing heat pump air conditioner at severe cold season, outdoor temperature crosses when low that heating efficiency descends and the problem of frosting easily, the utility model proposes a kind of air preheat type finned tube evaporator, this heat exchanger can significantly improve the heating efficiency of heat pump air conditioner, can also avoid the generation of frosting phenomenon.
The technical scheme that its technical problem of solving the utility model adopts is: comprise the evaporimeter heat exchange pipeline, be installed in fin on the evaporimeter heat exchange pipeline, install evaporimeter heat exchange pipeline and fin shell, be installed in the fan on the shell, it is characterized in that: two parts pipeline before and after the evaporimeter heat exchange pipeline is divided into, the previous section pipeline is a waterpipe, and the aft section pipeline is a refrigerant tubing.
The evaporimeter heat exchange pipeline be shaped as circle or ellipse; Fin is plate fin or slitted fin or dull and stereotyped rectangle venetian blind type or corrugated plating arc shutter.
The waterpipe of described evaporimeter heat exchange pipeline and underground water or solar water heater or gas heater or running water are connected.
The beneficial effects of the utility model are: during this evaporimeter winter operation, can add hot air temperature earlier, improve the evaporating temperature of heat pump in winter and then the heating efficiency of raising heat pump, fundamentally solved the low heat pump efficiency decline problem that causes of outdoor temperature in winter, avoid the frosting phenomenon of heat pump outdoor heat exchanger in winter, improve the overall operation performance of heat pump air conditioner.Device structure is simple, and control is convenient.
Description of drawings:
Fig. 1 is the structural representation of air preheat type heat pump with evaporimeter.
Fig. 2 flows to schematic diagram for air preheat type heat pump with heat exchanging fluid in the evaporimeter.
The specific embodiment:
As shown in Figure 1, 2, the utility model comprises evaporimeter heat exchange pipeline 1, is installed in the shell 3 of fin 2, installation evaporimeter heat exchange pipeline 1 and fin 2 on the evaporimeter heat exchange pipeline 1, is installed in the fan 4 on the shell 3, two parts pipeline before and after evaporimeter heat exchange pipeline 1 is divided into, the previous section pipeline is a waterpipe 5, and the aft section pipeline is a refrigerant tubing 6.
Evaporimeter heat exchange pipeline 1 be shaped as circle or ellipse; Fin is plate fin or slitted fin or dull and stereotyped rectangle venetian blind type or corrugated plating arc shutter.
The waterpipe of described evaporimeter heat exchange pipeline and underground water or solar water heater or gas heater or running water are connected.
Water flows in the previous section pipeline of evaporimeter, and cold-producing medium flows in the aft section pipeline of evaporimeter, flows between the fin of air outside pipe, and is cold-producing medium entirely in the pipeline of traditional fin-tube heat exchanger.According to the outdoor temperature situation, the start-stop by control fan and water pump can realize that air only carries out independent heat exchange or successively carries out heat exchange with water, cold-producing medium with cold-producing medium.Winter is during operation of heat pump, air earlier with pipeline in water carry out heat exchange, after the intensification again with fin-tube heat exchanger in cold-producing medium carry out heat exchange.In addition, the water in the pipeline can adopt running water, also can utilize regenerative resource, as hot water in the solar water heater or underground water etc.In summer, this evaporimeter moves as condenser, looks in the weather condition decision pipeline whether water flowing, can reduce the condensation temperature of system during water flowing.
In Fig. 1, the parts of this utility model comprise fin, pipeline, fan and shell.Water flows in the previous section pipeline of evaporimeter, and cold-producing medium flows in the aft section pipeline of heat transmission equipment, flows between the fin of air outside pipeline, and fin is used for strengthening the coefficient of heat transfer of air side.In Fig. 2, the heat exchanging fluid type of flow in this evaporimeter mainly is described, air at first skims over water-filled pipeline, is heated, and then skims over the pipeline that is full of cold-producing medium, carries out cold and hot exchange with cold-producing medium, and cold-producing medium absorbs heat from air.
