Abstract

The utility model discloses an anti-icing defrosting device which comprises a controller, a compressor, a condenser, an expansion valve and an evaporator, wherein the compressor, the condenser, the expansion valve and the evaporator are connected end to end through pipelines. The condenser is further connected with a solenoid valve through a pipeline, the solenoid valve is connected with an auxiliary electric defroster through a pipeline, and the auxiliary electric defroster is connected to the pipeline between the expansion valve and the evaporator through a pipeline. A temperature control probe is arranged on the pipeline between the evaporator and the compressor, and is connected with the input end of the controller. The output end of the controller is electrically connected with the input end of the solenoid valve and the input end of the auxiliary electric defroster. The anti-icing defrosting device guarantees defrosting, and meanwhile the supply of hot water is effectively guaranteed. The anti-icing defrosting device solves the problem that the evaporator is frozen due to the fact that traditional hot air defrosting is insufficient. The anti-icing defrosting device is flexible in design, auxiliary electric devices with different powers can be arranged according to the size of a defrosting pipe, hot air bypass defrosting is small in impact on a heat pump system, system leaking points are reduced, and safety performance is high.

Description

A kind of anti-freeze defrosting device
Technical field
The utility model relates to a kind of anti-freeze defrosting device.
Background technology
Up to now, have on the market many air source heat pumps, it mostly adopts four-way change-over valve to solve defrosting in winter problem, and the method is impacted large to compressor, and the defrosting effect is general, is prone to defrost repeatedly winter, and unit durability reduces.
The utility model content
The deficiency existed for prior art, the utility model purpose is to provide the effective anti-freeze defrosting device of a kind of defrosting.
To achieve these goals, the utility model is to realize by the following technical solutions:
The utility model comprises controller and the compressor, condenser, expansion valve and the evaporimeter that are connected by the pipeline first place; Condenser also connects a magnetic valve by pipeline, and magnetic valve connects an auxiliary electric defroster by pipeline, and auxiliary electric defroster is connected on the pipeline between described expansion valve and evaporimeter by pipeline; Pipeline between evaporimeter and compressor is provided with temperature probe, and temperature probe is connected with the controller input; The output of controller is electrically connected to the input of magnetic valve and auxiliary electric defroster.
Above-mentioned evaporimeter place is provided with a blower fan.
What above-mentioned evaporimeter specifically adopted is finned evaporator.
The utility model, when ensureing defrost, effectively guarantees the supply of hot water; The utility model overcomes traditional hot gas defrost deficiency, causes the icing difficult problem of evaporimeter; The utility model flexible design, can, according to defrost pipe size, be equipped with the auxiliary electric installation of different capacity; The hot-gas bypass defrost, little to the heat pump impact, reduced the system leak source, safe.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is an embodiment of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, the utility model comprises controller 7, one compressors 1, compressor 1 connects a condenser 2 by pipeline, condenser 2 connects an expansion valve 3 by pipeline, and expansion valve 3 connects an evaporimeter 4 by pipeline, and evaporimeter 4 connects compressor 1 by pipeline.Condenser 2 also connects a magnetic valve 6 by pipeline, and magnetic valve connects auxiliary electric defroster 5 by pipeline, and auxiliary electric defroster 5 is connected on the pipeline between expansion valve 3 and evaporimeter 4 by pipeline.
Pipeline between evaporimeter 4 and compressor 1 is provided with temperature probe 8, and temperature probe 8 is connected with the input of controller 7; The output of controller 7 is electrically connected to the input of magnetic valve 6 and auxiliary electric defroster 5.Magnetic valve 6 and auxiliary electric defroster 5 are controlled and operation simultaneously by controller 7 simultaneously.
In defrost process, hot gas defrost magnetic valve 6 and auxiliary electric 5 while of defroster continuous service, stop after machine 1 suction temperature to be compressed rises, hot gas defrost deficiency while avoiding air source heat pump to move in the winter time, and the device 4 that effectively avoids evaporating freezes.
The present embodiment, at evaporimeter, 4 places are provided with a blower fan.
The present embodiment, what evaporimeter 4 specifically adopted is finned evaporator.
When air source heat pump needs defrosting, provide instruction by controller 7, hot gas defrosting magnetic valve 6 is opened, after condensation, the utilizing waste heat for refrigeration agent is after auxiliary electric defroster 5 heats up, enter evaporimeter 4, not only guaranteed the supply of hot water, also ensured defrost, effectively utilize the hot-gas bypass defrost advantage little to system shock, improve system run all right and equipment life.
The utility model utilizes condensed cold-producing medium waste heat to carry out defrost after magnetic valve 6 and auxiliary electric defroster 5, but flexible design configures corresponding heating power, guarantees defrosting efficiency when ensureing hot water heating, has avoided the impact of four-way commutation to compressor.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
