Abstract
The utility model provides an evaporator with an adjustable heat exchange area, comprising an air heat exchanger and a blower, wherein one group of liquid distributing pipes which are arranged at intervals pass through the air heat exchanger from inside; distributors are arranged at inlets of the liquid distributing pipes and outlets of the liquid distributing pipes are provided with air collecting pipes, wherein solenoid valves are arranged at inlet ends of the liquid distributing pipes. The evaporator with the adjustable heat exchange area, disclosed by the utility model, is simple in structure; the solenoid valves are additionally arranged on the liquid distributing pipes and can be matched with a frequency conversion blower and a speed-adjusting blower to be used, so as to adjust forced ventilation quantity, heat exchange area and volume of the air heat exchanger; and two methods are matched so that the aim of ideally controlling an evaporation temperature of the air heat exchanger in a large environmental temperature-changing range is achieved.
Description
Technical field
The utility model relates to a kind of evaporimeter, especially a kind of adjustable evaporimeter of heat exchange area that is used for air source hot pump water heater.
Background technology
The existing wind heat exchanger in market (like accompanying drawing one) as the air source hot pump water heater evaporimeter; Heat exchange area on the wind heat exchanger 1 is fixed; If need the adjustment evaporation capacity, in the compressor safety zone, can only adjust the rotating speed of blower fan 2 to guarantee evaporating temperature; Adjust the heat of wind heat exchanger 1 through changing wind heat exchanger 1 force ventilated air quantity, thereby guarantee the evaporating temperature scope.Through the mode of adjustment air quantity, adjust the limited in one's ability of evaporating temperature.In unit design, generally adopt three retainings or two retaining adjustable speed fans, guarantee that in middle environment temperature for example 20 when spending, and is in middling speed (medium air quantity); When low temperature, when for example-20 spending, be in (maximum quantity of wind) at a high speed; When high temperature, for example 43 when spending, and is in low speed (minimum air quantity).Also have and adopt frequency conversion fan adjustment air quantity, but higher because of cost, use less.These two kinds of methods all are to adjust evaporating temperature through the adjustment air quantity merely, in actual use; There is open defect: at first, can not cover all environment temperatures commonly used, the evaporating temperature scope that guarantees; Make the compressor of air source hot pump water heater; Often work in outside the safe evaporating temperature, for example: below the evaporating temperature-23 or more than 12 degree, thereby influence the result of use and the service life of compressor.Another open defect of adjusting the evaporating temperature of wind heat exchanger by the adjustment air quantity is: under the less situation of evaporation load; Refrigerant mass fluxes in the wind heat exchanger is less; Be equivalent to below half of biggest quality flow, the heat exchange area of wind heat exchanger and the constancy of volume make refrigerant mass flow rate reduce greatly; Thereby strengthen the evaporation resistance loss, and influence the oil return ability of refrigeration system.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of heat exchange area adjustable evaporimeter, makes it adapt to temperature in larger scope.
The utility model solves the technical scheme that its technical problem adopts: the adjustable evaporimeter of this heat exchange area; Comprise wind heat exchanger, blower fan; Pass one group of separating tube spaced apart in the wind heat exchanger; The import department of separating tube is provided with distributor, and the outlet of separating tube is provided with discharge, and wherein the entrance point place of separating tube is provided with magnetic valve.The break-make of refrigerating fluid in the magnetic valve controllable sub liquid pipe, thus the effective disengagement area on the control evaporimeter reaches in big variation of ambient temperature scope, the purpose of desirable control wind heat exchanger evaporating temperature.
Separating tube has five the tunnel, and wherein the two-way separating tube is provided with magnetic valve.Can regulate effective disengagement area in certain limit like this.
Magnetic valve is located at the top two-way of separating tube.Guarantee carrying out smoothly of evaporimeter defrosting like this.
The effect that the utility model is useful is: the utility model simple in structure; On separating tube, increase magnetic valve; Can cooperate frequency conversion fan and adjustable speed fan to use, forced ventilation amount and the heat exchange area and the volume of adjustment wind heat exchanger, two kinds of methods are used; Reach in big variation of ambient temperature scope the purpose of desirable control wind heat exchanger evaporating temperature.
Description of drawings
Fig. 1 is the structural representation of evaporimeter in the prior art;
Fig. 2 is the structural representation of the utility model.
Description of reference numerals: wind heat exchanger 1, blower fan 2, separating tube 3, distributor 4, discharge 5, magnetic valve 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: the adjustable evaporimeter of this heat exchange area; Comprise wind heat exchanger 1, blower fan 2; Pass one group of separating tube spaced apart 3 in the wind heat exchanger 1; The import department of separating tube 3 is provided with distributor 4, and the outlet of separating tube 3 is provided with discharge 5, and wherein the entrance point place of separating tube 3 is provided with magnetic valve 6.Separating tube 3 has five the tunnel, and wherein top two-way separating tube 3 is provided with magnetic valve 6.
The utility model is applied to the adjustable wind heat exchanger of heat exchange area of Teat pump boiler; Can cooperate frequency conversion fan and adjustable speed fan to use; The heat exchange area and the volume of the forced ventilation amount of adjustment wind heat exchanger and adjustment wind heat exchanger, two kinds of methods are used; Reach in big variation of ambient temperature scope the purpose of desirable control wind heat exchanger evaporating temperature.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
