Abstract
The utility model discloses a heat pump water heater, including a compressor, a four-way valve, a condenser, a throttling device and evaporators; the compressor is connected with the four-way valve through a refrigerant conduit; the four-way valve is connected with the condenser through the refrigerant conduit; the devices are linked in a circle through the refrigerant conduits; heat exchangers are provided on the evaporators for preventing freezing of the evaporators; a first shunting conduit arranged between the throttling device and the condenser is connected with the evaporators; and a second shunting conduit arranged between a cut-off device and the condenser is connected with the evaporators, thus enabling circulation of a refrigerant in the evaporators. The heat pump water heater solves a problem of condensation pressure reduction in a heating circulation as the refrigerant is fed into the heat exchangers of the evaporators as a whole; additionally, only first and second shunting conduits are needed so as to simplify a structure and increase production efficiency; and the heat pump water heater can not only prevent freezing of the evaporators, but also reduce heat loss, and enhance working performance and refrigerating rate.
Description
Technical field
The utility model relates to a kind of Teat pump boiler, specifically, relates to a kind of a kind of Teat pump boiler that can effectively remove the frost in the outdoor location that appears at heat pump.
Background technology
Usually, kind of refrigeration cycle comprises compressor, condenser, cut-off equipment, reaches evaporimeter.If evaporimeter absorbs the heat of high-temperature part, condenser is partly emitted heat to low temperature so.The principle that can utilize evaporimeter to absorb the high-temperature part heat is made device for cooling, as air-conditioner and refrigerator.Can utilize condenser to make heater, for example heat pump to the exothermic principle of low temperature part.
In addition, because evaporimeter and condenser be as heat exchanger, by optionally changing the flow direction of cold-producing medium, Teat pump boiler comprises that compressor, evaporimeter, condenser and cut-off equipment can realize heating operation.
But the problem that such Teat pump boiler exists is to understand frosting as evaporimeter when the heating operation.Because when carrying out in the winter time, when outdoor peripheral temperature is lower than zero degree.Especially at cold district, temperature always is lower than zero degree, and condensed water appears in evaporimeter, directly build-ups ice then.
In addition, this evaporimeter includes a plurality of metallic plates (fin) that are arranged in its inside, and makes the cold-producing medium vertical current cross the conduit of this fin.If frosting between fin, air duct is blocked, and the pressure loss, power consumption and noise increase, thereby greatly reduce rate of heat exchange.
In order to prevent that outdoor location from freezing, and discloses a kind of operation that prevents frosting of regular chiller-heat pump.Owing to prevent that the operation of frosting is identical with refrigerating operaton, condenser is operated as finishing into heat, thereby has prevented frosting.But this operation that prevents frosting is regularly to carry out at the heating run duration.Reduced the thermal efficiency like this.
The utility model content
A purpose of the present utility model provides a kind of Teat pump boiler with anti-frosting device, and this device device that can effectively avoid evaporating freezes, and reduces heat loss, improves the refrigeration rate and the coefficient of performance.
The utility model is achieved in that
A kind of Teat pump boiler comprises compressor, cross valve, condenser, throttling arrangement and evaporimeter, and compressor connects cross valve by coolant conduits, and cross valve connects condenser by coolant conduits, and these devices constitute circulation by coolant conduits and connect; Condenser connects throttling arrangement, and flow controller connects evaporimeter, on this evaporimeter heat exchanger is arranged, and the device that is used to avoid evaporating freezes; There is first shunt catheter to connect evaporimeter between throttling arrangement and the condenser, has second shunt catheter to connect evaporimeter between cut-off equipment and the condenser, cold-producing medium is circulated in evaporimeter.
Emit heat by the cold-producing medium that flows to the heat exchanger in the same evacuator body device, the device that avoids evaporating freezes.
In the beneficial effects of the utility model be: overcome in the pyrogenicity circulation, cold-producing medium is sent into heat exchanger in the same evacuator body device, reduced condensing pressure.In addition, owing to only need first and second shunt catheters, thereby simplify the structure, improved productivity ratio.The device that not only can avoid evaporating effectively freezes, and can also reduce heat loss, improves service behaviour and duty.
Description of drawings
Fig. 1 is the heat pump schematics of the utility model embodiment.
Among the figure: 1, compressor; 2, cross valve; 3, condenser; 4, throttling arrangement; 5, evaporimeter; 501, heat exchanger; 6 first shunt catheters; 7, coolant conduits; 8, second shunt catheter; 9, water tank.
The specific embodiment
Describe the most preferred embodiment of a Teat pump boiler of the present utility model in detail below with reference to Fig. 1.
Identical with the heat pump of prior art, a kind of Teat pump boiler comprises: compressor 1, cross valve 2, condenser 3, throttling arrangement 4, evaporimeter 5.These elements are linked in sequence each other, constitute the pyrogenicity circulation.
Describe this below in detail and prevent the frosting device.
In more detail, first shunt catheter 6 is arranged on the precalculated position of the coolant conduits 7 that is used to connect evaporimeter 5 and condenser 3, and cold-producing medium is delivered to heat exchanger 501 in the same evacuator body device 5.Second shunt catheter 8 is arranged on the heat exchanger 501 in the same evacuator body device 5, carries out cold-producing medium circulation after the heat exchange so that make in cool cycles with evaporimeter 5, that is to say, gives throttling arrangement 4 this cold-producing medium.
At this moment, first shunt catheter 6 is connected with the coolant conduits 7 that is connected condenser 3 and throttling arrangement 4 with second shunt catheter 8.First shunt catheter 6 preferably is connected with coolant conduits 7 with predetermined interval with second shunt catheter 8.
In addition, consider that originally frosting is to occur in evaporimeter this fact below 5, preferably is arranged on first shunt catheter 6 below second shunt catheter 8.
Operation according to Teat pump boiler of the present utility model is described below.
At first, in the pyrogenicity aqueous mode, cold-producing medium is according to compressor 1, cross valve 2, condenser 3, the heat exchanger 501 in the same evacuator body device, throttling arrangement 4, the sequential loop of evaporimeter 5.This circulating path is simpler than prior art, and has reduced heat loss.
And in the hot water pattern, cold-producing medium is according to compressor 1, cross valve 4, condenser 3, the first shunt catheters 6, heat exchanger 501, the second shunt catheters 8 in the same evacuator body device, throttling arrangement 4, evaporimeter 5, cross valve 4, and the sequential loop of compressor 1.
In other words, if beginning hot water operation, cold-producing medium is according to compressor 1, cross valve 4, and condenser 3, the heat exchanger 501 in the same evacuator body device 5, and the sequential loop of evaporimeter 5 are so that provide heat to water tank 9.
At this moment, at the cold-producing medium of condenser 3, by first isocon 6, the heat exchanger 501 in same evacuator body device.Emit heat by the cold-producing medium that flows to the heat exchanger 501 in the same evacuator body device 5, the device 5 that avoids evaporating freezes.
