Abstract
The invention discloses a protector preventing discharge temperature of air conditioner compressor from being too high, an electromagnetic valve is arranged between a muffler of compressor connected with a liquid storage pot and a liquid pipe which can cause refrigerant to flaw toward an indoor evaporator and is connected with an outdoor heat exchanger, and the electromagnetic valve is opened when a temperature sensor arranged on the compressor senses the discharge pipe of the compressor is over the set value. The invention has the beneficial effects that the discharge temperature of compressor is protected to be not too high when system refrigerant is leaked and the compressor is avoided to be damaged as the discharge temperature is too high. Thus the compressor proctor can better improve product performance and prolong service life and improves product competitive capacity.
Description
Technical field
The present invention relates to a kind of air-conditioner, especially prevent the protective device of cooler compressor excessive discharge temperature.
Background technology
Air-conditioner is a kind of device that makes its inner refrigerant carry out the refrigeration of being made up of compression process, condensation process, expansion process and evaporation process or heat circulation.When air-conditioner carries out kind of refrigeration cycle, the refrigerant that becomes high-temperature high-pressure state through compressor compresses can flow to condenser under the guiding of cross valve, and in condenser, dispel the heat to the outside, when flowing through expansion valve, significantly reduce its temperature and pressure then, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter subsequently, flow back in the compressor again through fluid reservoir at last.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioner, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.It is then opposite with above-mentioned kind of refrigeration cycle process to heat circulation.Air-conditioner is divided into domestic air conditioner and commercial use air conditioner usually.Wherein commercial use air conditioner is divided into wind pipe type and embedded two kinds, and it mainly is used in the buildings such as office building, market.
Compressor is the core component of air-conditioner, as shown in Figure 1, the air-conditioner outdoor unit of prior art, the blast pipe 7 of compressor 1 links to each other with cross valve 4, the muffler 8 of compressor links to each other with fluid reservoir 3, cross valve 4 links to each other with outdoor heat converter 5, the refrigerant that carries out heat exchange through outdoor heat converter 5 flows into indoor evaporator (not shown) through the liquid pipe 9 that links to each other with outdoor heat converter, what flow in liquid pipe 9 is the liquid refrigerants of high pressure low temperature, what flow in muffler 8 is the low pressure gaseous coolant, also is connected with temperature sensor 2 at compressor 1.
Existing air-conditioning market off-premises station is bad to be the compressor problem mostly, and many compressor exhaust temperature is too high in the compressor problem, causes the compressor scaling loss.When compressor exhaust temperature is too high, can cause the compressor scaling loss on the one hand, on the other hand, can cause the air-conditioning exchange capability of heat to reduce.Usually during excessive discharge temperature, can only start the easier like this compressor damage that makes repeatedly by compressor.
Summary of the invention
In order to address the above problem, the invention provides a kind of when system's secondary refrigerant leakage, the protection compressor delivery temperature can be not too high, the protective device that prevents the cooler compressor excessive discharge temperature of avoiding compressor to damage because of excessive discharge temperature.
In order to achieve the above object; a kind of protective device that prevents the cooler compressor excessive discharge temperature of the present invention; at the muffler of the compressor that links to each other with fluid reservoir with refrigerant is flowed between the liquid pipe that links to each other with outdoor heat converter of indoor evaporator be provided with protective valve, when surpassing setting value according to the temperature of refrigerant in the blast pipe of the compressor of the temperature sensor perception on the compressor, opens protective valve.
Described protective valve is a magnetic valve
The invention has the beneficial effects as follows: when system's secondary refrigerant leakage, the delivery temperature of protection compressor can be not too high, avoids compressor to damage because of excessive discharge temperature.Therefore compressor protection device performance and the service life that can better improve product, improve competitive power of product.
Description of drawings
Fig. 1 is the air-conditioner outdoor unit work structuring figure of prior art.
Fig. 2 is the air-conditioner outdoor unit work structuring figure that has the protective device that prevents the cooler compressor excessive discharge temperature of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
The operation principle of air-conditioner of the present invention is identical with prior art; can be with reference to prior art; so no longer narration, the difference of the present invention and prior art is to have increased to have the protective device that prevents the cooler compressor excessive discharge temperature, is described in detail below:
As shown in Figure 2; the protective device that prevents the cooler compressor excessive discharge temperature of the present invention; at the muffler 8 of the compressor that links to each other with fluid reservoir 3 with refrigerant is flowed between indoor evaporator and the liquid pipe 9 that outdoor heat converter 5 links to each other be provided with magnetic valve 10, when surpassing setting value according to the temperature of refrigerant in the blast pipe 7 of the compressor of 2 perception of the temperature sensor on the compressor, opens by magnetic valve 10.
Compressor air-discharging protective device of the present invention solves the excessive discharge temperature problem of compressor when secondary refrigerant leakage, and when secondary refrigerant leakage, system pressure can slowly descend, and compressor exhaust temperature is sharply risen, and causes the compressor shutdown action.Behind the perseveration, make the compressor scaling loss.The present invention increases path between off-premises station liquid pipe place and compressor air suction mouth, use protective valve to be controlled.Compressor exhaust temperature rises when surpassing benchmark when system's secondary refrigerant leakage like this; protective valve is opened immediately; because the refrigerant in the liquid pipe is the liquid refrigerants of high pressure low temperature; and the refrigerant in the muffler of compressor is the low pressure gaseous coolant; by inhalant liquid pipe side refrigerant; the refrigerant temperature that flows into compressor is reduced, also just reduced compressor exhaust temperature, thereby reach the purpose of protection compressor.
In sum, content of the present invention is not limited in the above-described embodiment, and the knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the present invention, but this embodiment comprises within the scope of the present invention.
Claims (2)
1. protective device that prevents the cooler compressor excessive discharge temperature; it is characterized in that; at the muffler (8) of the compressor that links to each other with fluid reservoir (3) with refrigerant is flowed between indoor evaporator and the liquid pipe (9) that outdoor heat converter (5) links to each other be provided with protective valve, when surpassing setting value according to the temperature of refrigerant in the blast pipe (7) of the compressor of the temperature sensor on the compressor (2) perception, opens protective valve.
