Abstract
The utility model provides an air that defrosting reliability is high can water heater, air that defrosting reliability is high can water heater includes the condenser, condenser one end is connected with the one end and the first throttle part of compressor respectively, the compressor other end is connected with the first end of evaporimeter, the other fan that is equipped with of evaporimeter, evaporimeter second end is connected with first throttle part and second throttle part respectively, second throttle part with the other end of condenser is connected. Need not stop to heat the operation during defrosting, just the heating capacity reduces for the air conditioner can not cause the decline that heats indoor temperature, is used for heat pump water heater can not cause hot water temperature's decline, and it is synthesized efficiency and obviously improves, and the reliability obviously improves.
Description
Technical field
This utility model is the air-source water heater that a kind of reliability that defrosts is high, belongs to air-source water heater equipment technical field.
Background technology
During air-source water heater operation of heat pump, need from low temperature environment to hot environment heat transfer, the heat exchanger surface temperature of low temperature side is inevitably less than low temperature side ambient temperature, when low temperature side ambient temperature low to close to zero degree time, cryogenic heat exchanger surface temperature can lower than zero degree, in this case, low-temperature side heat exchanger surface is it is possible to frosting, frosting can reduce the efficiency of heat exchanger and air heat-exchange, and therefore, heat pump needs defrosting function.
And the Defrost mode of prior art air energy water heater is: system condenser and evaporator function are exchanged after outdoor heat exchanger surface frost accumulated being detected by operation of heat pump by the action of cross valve, namely low temperature side (outside) becomes condenser, high temperature side becomes vaporizer, system, from the lateral low temperature side transmission heat of high temperature, is recovering normal heat pump operation after low-temperature side heat exchanger surface frost layer being melted with this partial heat.This Defrost mode has the drawback that defrosting is not only not heat also to absorb heat from high temperature side, can cause the decline of high temperature side ambient temperature.During for air-conditioning heating, will result in indoor air temperature and decline, the decline of hot water temperature can be caused for Teat pump boiler.
Utility model content
For the deficiency that prior art exists, this utility model purpose is to provide the air-source water heater that a kind of reliability that defrosts is high, and to solve the problem proposed in above-mentioned background technology, this utility model is reasonable in design, and defrosting effect is good, and reliability is high.
To achieve these goals, this utility model is to realize by the following technical solutions: the air-source water heater that described defrosting reliability is high includes condenser, described condenser one end is connected with one end of compressor and first throttle parts respectively, the described compressor other end is connected with the first end of vaporizer, it is provided with blower fan by described vaporizer, described vaporizer the second end is connected with first throttle parts and second section stream unit respectively, and described second section stream unit is connected with the other end of described condenser.
Wherein, described condenser has the water tank of coil pipe, high-efficiency tank or sleeve pipe in being.
Wherein, the air-source water heater that described defrosting reliability is high also includes gas-liquid separator, and described gas-liquid separator is series between described vaporizer and compressor.
Wherein, described efficient filling is provided with outlet and water inlet.
Wherein, low tension switch also it is in series with between described gas-liquid separator and compressor.
Wherein, high-voltage switch gear also it is in series with between described condenser and compressor.
Wherein, described first throttle parts, second section stream unit are electric expansion valve or capillary tube.
Wherein, it is provided with temperature sensor in described vaporizer.
The beneficial effects of the utility model: heating operation need not be stopped during defrosting, simply heating capacity reduces, the decline heating indoor temperature is not resulted in for air-conditioning, the decline of hot water temperature is not resulted in for Teat pump boiler, Defrost mode that its comprehensive energy efficiency switches apparently higher than cross valve and system does not need cross valve, reliability significantly improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the air-source water heater that this utility model defrosting reliability is high.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains this utility model, be not used to limit this utility model.
As shown in Figure 1, the air-source water heater that this utility model defrosting reliability is high, the air-source water heater that described defrosting reliability is high includes condenser 1, cold-producing medium is freon, condenser has water tank or the various ways such as high-efficiency tank, sleeve pipe of coil pipe in can being, can also be other forms such as finned heat exchanger for air-conditioning.Described condenser one end is connected with one end of compressor 2 and first throttle parts 3 respectively, the described compressor other end is connected with the first end of vaporizer 4, blower fan 5 it is provided with by described vaporizer, described vaporizer the second end is connected with first throttle parts and second section stream unit 6 respectively, and described second section stream unit is connected with the other end of described condenser.Described efficient filling is provided with outlet and water inlet.Described first throttle parts, second section stream unit are electric expansion valve or capillary tube.
The air-source water heater that described defrosting reliability is high also includes gas-liquid separator 7, and described gas-liquid separator is series between described vaporizer and compressor.Low tension switch 8, muffler 11 also it is in series with between described gas-liquid separator and compressor.High-voltage switch gear 9, exhaustor 12 also it is in series with between described condenser and compressor.Being provided with temperature sensor 10 in described vaporizer, this temperature sensor can be used to detect whether frosting.
When this utility model uses: operation of heat pump opens throttle part between compressor exhaust pipe and outdoor heat exchanger freon import (can be capillary tube can also be expansion valve) after heat exchanger surface frost accumulated being detected, make a part of freon be directly entered outdoor heat exchanger (vaporizer) by this throttle part, utilize the heat of this part freon to remove the frost on outdoor heat exchanger surface.Detect that frost layer closes this throttle part after melting completely, recover normal heat pump operation.The advantage of this Defrost operation pattern is in that when defrosting need not stop heating operation, simply heating capacity reduces, the decline heating indoor temperature is not resulted in for air-conditioning, the decline of hot water temperature is not resulted in for Teat pump boiler, Defrost mode that its comprehensive energy efficiency switches apparently higher than cross valve and system does not need cross valve, reliability significantly improves.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this utility model, although this utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature carries out equivalent replacement.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
