Abstract
The utility model discloses an evaporator with defrosting device, which comprises an evaporator heat transfer fin and a multi-row evaporator copper tube disposed on the evaporator heat transfer fin, wherein, on the evaporator heat transfer fin at one side of the multi-row evaporator copper tube is inserted at least one row of heating wire of an electric heater; one side of the heating wire of the electric heater is provided with a fan; the fan transfers evenly the heat generated by the heating wire of the electric heater from the heating wire to the copper tube surface of multi-row evaporator copper tube at the sideface thereof so as to directly eliminate the frost on the surface of the evaporator. On the premise of meeting consumer requirement for hot water temperature, the utility model can also reduce energy consumption and improve the stability of the machine set.
Description
Technical field
The utility model relates to hot water supply system, specifically, relates to the improvement of the evaporation structure with defroster.
Background technology
The hot water unit that traditional heat pump heats when working, the frosting situation occurs under being lower than 0 ℃ environment temperature, influenced the operate as normal of unit, and frosting causes unit can't produce hot water for a long time.Mostly the method that conventional rack is tackled is to adopt the traffic direction of electrical heating defrosting or counter-rotating heat pump, because under long low temperature environment, common electrically heated efficient is low, defrosting effect is poor; And the method for the traffic direction of the heat pump of taking to reverse, under the situation of of short duration frosting, be feasible, but frequent system inversion operation will appear in the unit that works long hours under low temperature environment, working life to unit has very big influence, and causing can't operate as normal.In order to continue to produce hot water, conventional rack adopts auxiliary electrically heated mode to produce hot water, because electrically heated efficient is low, generally between 0.8～0.9, and electricity is that high-grade energy is used for directly heating that to produce hot water be to be a kind of very big waste to the energy.
Under the more frequent situation of variation of ambient temperature, the heating capacity of unit has very big variation, and the evaporation degree of cold-producing medium in evaporimeter also very big variation can occur.When environment temperature was low, evaporation effect was relatively poor, just had a lot of liquid in the muffler; When environment temperature was high, evaporation effect was better, generally liquid can not occur.Hot water machine is worked being lower than under 0 ℃ the environment temperature, and when frosting appearred in unit, what at first adopt was that the mode of heat pump counter-rotating defrosts; When the decline that environment temperature continues, when causing the frequency of unit frosting very high, the mode of reusable heat pumping system counter-rotating at this moment defrosts, and not only can cause very big injury to compressor, and the heating effect of unit is also very poor.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective of the prior art, by carry out direct electrical heating defrosting at evaporator surface, is guaranteeing under the prerequisite that the user requires the hot water temperature energy consumption that also can save unit, the stability of raising unit.
For achieving the above object, the technical scheme that the utility model provides is as follows: construct a kind of evaporimeter with defroster, comprise the evaporimeter thermofin, be arranged on the many rows evaporimeter copper pipe on the evaporimeter thermofin, on the evaporimeter thermofin of described many row's evaporimeter copper pipe one sides, be interspersed with the heater strip of at least one row's electric heater, side at the heater strip of electric heater is provided with fan, the heat that this fan sends the heater strip of electric heater is evenly delivered to many rows evaporimeter copper pipe surface of its side from heater strip, and the frost on the evaporator surface is directly removed.
Producing effect of evaporimeter with defroster described in the utility model is: by carry out direct electrical heating defrosting at evaporator surface, guaranteeing under the prerequisite that the user requires the hot water temperature, also can save the energy consumption of unit, improve the stability of unit, employing is interspersed electric heater heating wire in the evaporimeter thermofin, carry out direct electrical heating defrosting from the surface of evaporimeter, can guarantee that unit works normally under the environment temperature below-5 ℃.
