Abstract

The utility model provides an air conditioner which comprises a compressor, a four-way valve, a condenser, a normally-open electromagnetic valve, a capillary pipe, an indoor evaporator and an electric control board. The compressor, the four-way valve, the condenser, the normally-open electromagnetic valve, the capillary pipe and the indoor evaporator are sequentially connected with each other. The normally-open electromagnetic valve is electrically connected with the electric control board. The air conditioner is characterized in that: a branch which is formed by serial connection between the normally-open electromagnetic valve and the pressure reduction capillary pipe is arranged on a pipeline between an outlet of the condenser and an air return opening of the compressor, and is connected with the normally-open electromagnetic valve, the capillary pipe and the indoor evaporator in parallel; and the normally-open electromagnetic valve is electrically connected with the electric control board. Compared with the prior art, the air conditioner has the following benefits: as the action of the electromagnetic valve changes the flowing direction of a refrigerant, the flowing speed and quantity of the refrigerant are increased, and the defrosting time is shortened as well; the indoor electrical auxiliary heating is continued, which can make sure that the indoor temperature has no obvious fluctuation, thereby improving the comfort degree of users; moreover, few improvements are made on a system pipeline, and the manufacturing cost of an entire machine is low.

Description

A kind of air-conditioner
Technical field:
The utility model is a kind of air-conditioner, belongs to the improvement technology of air-conditioner.
Background technology:
Existing changes in temperature, the auxilliary heat air conditioner of electricity are when heating, if ambient temperature is lower, air-conditioner is meeting frosting on its outdoor condenser after operation a period of time, and at this moment, air-conditioner can enter the defrost pattern, and after defrost finished, air-conditioner could operate as normal.The existing air-conditioner defrost time generally needs about 10 minutes, and in defrost process, air-conditioner can be to indoor heating, and the temperature of opposite indoor evaporator can significantly be reduced to below-20 ℃.Particularly under the environment temperature of low temperature and high relative humidity, defrost more can frequently be carried out, thereby causes room temperature constantly to fluctuate, and influences user's comfortableness.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and guarantees that indoor temperature is stable, improves the air-conditioner of user's comfortableness.
The technical solution of the utility model is: a kind of air-conditioner, comprise compressor, cross valve, condenser, normal-open electromagnetic valve, capillary, indoor evaporator and automatically controlled plate, compressor wherein, cross valve, condenser, normal-open electromagnetic valve, capillary and indoor evaporator connect successively, normal-open electromagnetic valve is electrically connected with automatically controlled plate, it is characterized in that also being provided with and normal-open electromagnetic valve on the pipeline between the return-air mouth of the outlet of described condenser and compressor, capillary and indoor evaporator parallel connection by the closed type magnetic valve, the branch road of step-down capillary serial connection, the closed type magnetic valve is electrically connected with automatically controlled plate.
Above-mentioned closed type magnetic valve one end is connected with the outlet of condenser, and the other end is connected with the step-down capillary, and the step-down other end capillaceous is connected with the return-air mouth of compressor.
Above-mentioned step-down caliber capillaceous is greater than caliber capillaceous.
The utility model is owing to be connected with the branch road of being connected by closed type magnetic valve, step-down capillary with normal-open electromagnetic valve, capillary and indoor evaporator parallel connection on the pipeline between condensator outlet and the compressor return air mouth, when needing defrost, two magnetic valve actions, normal-open electromagnetic valve is closed, refrigerant directly returns compressor by closed type magnetic valve and step-down capillary flow from condensator outlet, need not pass through evaporimeter, at this moment, indoor auxiliary electrical heating can continue to open, and indoor fan turns round with gentle breeze.
The utility model has following beneficial effect compared with prior art: because the magnetic valve action has changed the refrigerant flow direction, accelerated refrigerant flow rate and flow, shortened the defrost time; The auxilliary heat of indoor electric continues to open, and assurance indoor temperature does not have obvious fluctuation, has improved user's comfortableness; Improvement for system pipeline is little, and the complete machine manufacturing cost is lower.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1: the utility model air-conditioner, comprise compressor 1, cross valve 2, condenser 3, normal-open electromagnetic valve 4, capillary 6, indoor evaporator 8 and automatically controlled plate 9, wherein compressor 1, cross valve 2, condenser 3, normal-open electromagnetic valve 4, capillary 6 and indoor evaporator 8 connect successively, normal-open electromagnetic valve 4 is electrically connected with automatically controlled plate 9, also be provided with and normal-open electromagnetic valve 4 on the pipeline between the return-air mouth of the outlet of condenser 3 and compressor 1, capillary 6 and indoor evaporator 8 parallel connections by closed type magnetic valve 5, the branch road of step-down capillary 7 serial connections, closed type magnetic valve 5 is electrically connected with automatically controlled plate 9.In the present embodiment, above-mentioned closed type magnetic valve 5 one ends are connected with the outlet of condenser 3, and the other end is connected with step-down capillary 7, and the other end of step-down capillary 7 is connected with the return-air mouth of compressor 1.The caliber of above-mentioned step-down capillary 5 is greater than the caliber of capillary 6.
When the utility model heats, when condenser 3 frostings are arrived to a certain degree, after automatically controlled plate 9 detected and reaches the defrost condition, complete machine entered the defrost state, at this moment, electricity auxilliary heat in indoor continues operation, fan electromotor 10 transfers the gentle breeze running to, and outside compressor 1 shuts down earlier, and normal-open electromagnetic valve 4, closed type magnetic valve 5 all move, after compressor 1 operation after after a while, refrigerant are flowed out from condenser 3 outlets through directly flowing back to compressor 1 behind closed type magnetic valve 5 and the step-down capillary 7.When through after a while, after automatically controlled plate detection defrost is finished, stop compressor 1, normal-open electromagnetic valve 4, closed type magnetic valve 5 all cut off the power supply, and withdraw from the defrost state through system after postponing a period of time, and compressor 1 restarts operation and heats.At this moment, flow into condenser 3 evaporation heat absorptions through capillary 6 and normal-open electromagnetic valve 4 backs after refrigerant flows out from evaporimeter 8, after cross valve 2 flows back to compressor 1, indoor fan electromotor 10 becomes the rotating speed of setting before the defrost simultaneously.Because in the defrost process, the auxilliary heat of indoor electric is continuously indoor heating, makes the indoor temperature not have obvious fluctuation, thereby has improved user's comfortableness.
