Description
Technical field
The utility model relates to a kind of household electrical appliance, especially a kind of heat pump air conditioner.
Background technology
Usually domestic air conditioning divides Dan Wenji and two two kinds of air-conditionings of warm machine, for two temperature air-conditionings when making heat pump and heat, when outdoor environment temperature lower, under the bigger situation of humidity, air-conditioner operation a period of time, condenser surface will have the frosting phenomenon to produce, and can have a strong impact on refrigerant like this and evaporate in condenser, promptly cause heating capacity to descend or deficiency, all heat pump air conditioners have all designed defrost function for this reason.
In the existing heat pump air conditioner defrost process, outdoor condensation temperature is very low, again through relatively long capillary-compensated, and enter the evaporator evaporation amount seldom, so suction temperature is all relative with back pressure very low, cause delivery temperature, pressure at expulsion relatively low indirectly, this defrosting cycle that just extended has shortened the time of heating.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can be quicker, the family expenses quickly defrosting heat pump air conditioner of more thorough defrosting.
The technical scheme in the invention for solving the technical problem is: a kind of family expenses quickly defrosting heat pump air conditioner, it comprises compressor, condenser, low-pressure shutoff valve, high-pressure stop valve and evaporimeter, one end of described compressor is connected with condenser, the other end is connected with evaporimeter, between condenser and evaporimeter, be provided with high-pressure stop valve, between evaporimeter and compressor, be provided with low-pressure shutoff valve, also be provided with magnetic valve and throttling arrangement, described throttling arrangement is arranged between condenser and the high-pressure stop valve, one end of described magnetic valve is arranged between throttling arrangement and the high-pressure stop valve, and the other end of magnetic valve is arranged between low-pressure shutoff valve and the compressor.
Described family expenses quickly defrosting heat pump air conditioner, described throttling arrangement is an electric expansion valve.
Described family expenses quickly defrosting heat pump air conditioner, described throttling arrangement is a capillary, and described capillary is two sections, and described magnetic valve is connected between two sections capillaries.
The present invention has been because increased magnetic valve and throttling arrangement, short circuit indoor evaporator, improved the suction temperature and the pressure of inspiration(Pi) of compressor significantly.Help the raising Compressor Discharge Pressure like this, and accelerated the refrigerant circulation, can largely shorten defrosting time, and lengthening normally heats the time, has utilized heat pump to heat more fully.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 of the present utility model;
Fig. 2 is the structural representation of embodiment 2 of the present utility model.
The specific embodiment
As shown in Figure 1, family expenses quickly defrosting heat pump air conditioner of the present utility model, it comprises compressor 1, condenser 2, low-pressure shutoff valve 7, high-pressure stop valve 5 and evaporimeter 6, one end of compressor 1 is connected with condenser 2, the other end is connected with evaporimeter 6, between condenser 2 and evaporimeter 6, be provided with high-pressure stop valve 5, between evaporimeter 6 and compressor 1, be provided with low-pressure shutoff valve 7, between condenser 2 and low-pressure shutoff valve 5, be in series with capillary 3 and capillary, also be provided with magnetic valve 8, one end of magnetic valve 8 is connected between capillary 3 and the capillary 4, and the other end is connected between low-pressure shutoff valve 7 and the compressor 1.
As shown in Figure 2, family expenses quickly defrosting heat pump air conditioner of the present utility model, it comprises compressor 1, condenser 2, low-pressure shutoff valve 7, high-pressure stop valve 5 and evaporimeter 6, one end of compressor 1 is connected with condenser 2, the other end is connected with evaporimeter 6, between condenser 2 and evaporimeter 6, be provided with high-pressure stop valve 5, between evaporimeter 6 and compressor 1, be provided with low-pressure shutoff valve 7, between condenser 2 and low-pressure shutoff valve 5, be provided with electric expansion valve 9, also be provided with magnetic valve 8, one end of magnetic valve 8 is connected between electromagnetic expanding valve 9 and the high-pressure stop valve 5, and the other end is connected between low-pressure shutoff valve 7 and the compressor 1.
Operation principle of the present utility model is:
At first original capillary is divided into two sections, two sections length is under the prerequisite that guarantees suitable compressor air suction pressure and suction temperature, can design coupling voluntarily according to producer's needs, be connected with a three-way pipe between capillary 3 and the capillary 4, normally freeze, magnetic valve 8 is normally closed when heating.If throttling arrangement is an electric expansion valve 9 because its adjustable range is very wide, the interface of normally closed solenoid valve can design as accompanying drawing after electric expansion valve 9.When air-conditioning system was carried out defrosting, electric expansion valve 9 can be adjusted to its aperture a very big value (setting according to pressure of inspiration(Pi) and suction temperature).Another interface of magnetic valve can design between reversal valve and low pressure valve.
The defrosting condition of system, each producer substantially all is according to the condenser coil temperature, or running time, is used as judging whether need the condition that defrosts.When system reaches the defrosting condition, system-down, the reversal valve commutation, system changes refrigerating operaton over to.Magnetic valve is opened simultaneously.It now is example with R22, the general 1.4MPa of pressure at expulsion, the general 0.9MPa of pressure of inspiration(Pi), if refrigerant only passes through capillary 3 throttlings, pressure can be between 0.9MPa～1.4aMP, and system normally moves for assurance, device can be adjusted in about 1.0MPa it, so also can debug out the length of capillary 3, deduct the length of capillary 3, can make the length of capillary 4 with the capillary length overall.Because the existence of capillary 4, refrigerant will be walked around the powerful local resistance of capillary 4 and the on-way resistance of indoor evaporator, from magnetic valve, flow through, directly enter compressor, like this with regard to indirect short circuit indoor evaporator, accelerated the refrigerant circulation, made the sensible heat of more refrigerant be used for defrosting, the defrosting cycle that this just accelerates.The heat pump that extended comparatively speaking heats the time.
Because refrigerant has only passed through the partial throttling device; therefore the pressure of inspiration(Pi) and the suction temperature of compressor all have certain lifting; pressure at expulsion also will largely promote (delivery temperature protection, the protection of compression case top of system are effectively normal) after compression, and defrosting is had tangible effect.
When system reaches when withdrawing from the defrosting condition, outdoor system is out of service, and magnetic valve 8 outages are simultaneously closed, and do normally heating in unlatching through system after the pre-set time.This has just finished a defrosting cycle.The opening time of magnetic valve can be synchronous with compressor shutdown, can accelerate the system pressure balance like this.The closed electromagnetic valve time can the system of being set in reach the defrosting condition time, because moment has increased the flow process of refrigerant, has reduced the pressure of inspiration(Pi) and the temperature of compressor, can more effective protection compressor.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
