Abstract
The utility model discloses a defrosting device utilizing an air source heat pump, and relates to the field of air source heat pumps. The device comprises an air source heat pump body, a heat exchanger, a water storage device and a spray head, wherein a refrigerant pipeline between a condenser and the inlet end of an evaporator in the air source heat pump body is provided with the heat exchanger, the water inlet end of the heat exchanger is communicated with the water storage device through the water pump, and the water outlet end of the heat exchanger is communicated with the spray head corresponding to a sprinkling evaporator. The device has the advantage that the frost of the air source heat pump can be effectively removed in the premise of ensuring the stable running of the system.
Description
[technical field]
The utility model relates to air source heat pump field, especially relates to a kind of for removing the defroster of air source heat pump frosting.
[background technology]
Known, air source heat pump is also referred to as air-source water heater or Teat pump boiler, its Related product has started to enter into the huge numbers of families of China, but, because air source heat pump very easily produces evaporimeter frosting phenomenon in running, and the appearance of frost layer not only can increase the heat exchange thermal resistance between air and working medium, the serious heat exchange property that hinders evaporimeter, and frost layer also can strengthen air after thickening and flow through the resistance of fin, thereby reduction air mass flow, cause the performance degradation of evaporimeter, and then cause heat pump product cisco unity malfunction even to damage; At present, for this problem, what generally adopt both at home and abroad is mainly the method for hot gas defrosting, the basic principle of the method is in the time of defrosting, four-way change-over valve to be commutated, allow heat pump by change cooling condition operation into for thermal condition, thereby the high temperature refrigerant gas that compressor is discharged is sent into outdoor heat exchanger heating finned tube, and then reaches the object of melting frost layer;
But, the method of this hot gas defrosting is in the time of operation, the interior space not only can not get heat, and because defrosting also will absorb the indoor heat of a part, therefore cause indoor temperature to decline, even also can produce cold wind sense, finally cause in the time proceeding to heating operation, the rise time of indoor temperature is long, is not only unfavorable for energy-conservationly, but also can have influence on the comfortableness of indoor temperature, this is mainly from compressor because of the heat defrosting, the shortage of heat of its supply, the time of defrosting is just long, the energy loss of defrosting is also larger, in addition, the steam generating after frost layer is melted is easily detained on outdoor heat exchanger surface after defrosting, this has directly caused near water vapour content heat exchanger higher, in the time of heat pump again heat supply, these steam will preferentially generate ice-nucleus, and then cause accelerating frosting, impact recovers heat supply, simultaneously, cross valve commutation frequently also can cause damage to compressor, be that high-low pressure part handoff procedure can produce more serious impact to each parts, therefore cause system to occur " oil of running quickly " phenomenon, have influence on the reliability of system,
In sum, the problem of evaporimeter frosting is restricted the air source heat pump product of applying energy-conserving and environment-protective, and especially in the northern area of China, therefore, how effectively to remove frosting just becomes the key point of promotion and application air source heat pump product.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of air source heat pump defrosting device, the frosting that described device can effectively be removed air source heat pump under the prerequisite of safeguards system stable operation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of air source heat pump defrosting device, described device comprises air source heat pump body, heat exchanger, water receiver and shower nozzle; In described air source heat pump body, be positioned on condenser and evaporator end refrigerant line before heat exchanger is installed, the water inlet end of this heat exchanger is communicated with water receiver by water pump, and the water side of heat exchanger is communicated with the shower nozzle of corresponding spraying evaporator.
Described air source heat pump defrosting device, described water pump is controlled startup automatically by the temperature sensor being arranged in air source heat pump body.
Owing to adopting technical scheme as above, the utlity model has following beneficial effect:
Air source heat pump defrosting apparatus structure described in the utility model is simple, easy to use; Described device not only can effectively be removed the frosting of air source heat pump, and in defrost process also without stopping operation of heat pump, thereby not only solved the cross valve problem frequently that commutates, also reached and raised the efficiency simultaneously, reduce energy consumption, the object of safeguards system stable operation.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, air source heat pump body; 2, heat exchanger; 3, water receiver; 4, shower nozzle; 5, condenser; 6, evaporimeter; 7, water pump.
[specific embodiment]
Can explain in more detail the present invention by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Air source heat pump defrosting device described in 1 by reference to the accompanying drawings, described device comprises air source heat pump body 1, heat exchanger 2, water receiver 3 and shower nozzle 4; In described air source heat pump body 1, be positioned on the refrigerant line before the entrance point of condenser 5 and evaporimeter 6 heat exchanger 2 is installed, thereby make the cold-producing medium of the HTHP that air source heat pump produces must formerly pass through heat exchanger 2 before entering condenser 5 and evaporimeter 6; Because the water inlet end of heat exchanger 2 is communicated with water receiver 3 by water pump 7, the water side of heat exchanger 2 is communicated with the shower nozzle 4 of corresponding spraying evaporator 6, therefore, the cold water of introducing by water pump 7 can utilize the cold-producing medium that heat exchanger 2 and temperature are higher carry out heat exchange and become hot water, and then be sprayed onto on evaporimeter 6 by shower nozzle 4, thereby reach the object of defrosting and preventing frosting, the heat that described device not only produces air source heat pump body has carried out effective heat exchange and has reasonably utilized, but also can in the normal work of heat pump, defrost;
As required, described water pump 7 can be controlled startup automatically by the temperature sensor that is arranged on relevant position in air source heat pump body, or by manually keeping the continuous running of water pump 7, in the time of the non-frosting state of outdoor environment in air source heat pump body 1, water pump 7 is not worked, in the time of the frosting state of outdoor environment in air source heat pump body 1, water pump 7 brings into operation, and reaches the object of defrosting and preventing frosting on evaporimeter 6 surfaces by the hot water spray that heat exchange is obtained; In addition, when described device is during at summer operation, can also directly cold water be pumped and is sprayed on condenser 5 by water pump 7, thereby effectively reduce the temperature of cold-producing medium, and the delivery temperature of heat pump and pressure at expulsion, and then guarantee the even running of unit and improved refrigerating capacity, when described device ensures defrosting in not only can be in the winter time, can not have influence on heating effect, and can also lower the temperature to condenser in the time of summer, reduce delivery temperature and pressure thereby reach, improve the object of refrigerating capacity and reduction energy consumption.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
