Description
Technical field
The present invention relates to air-conditioning technical field, the air-conditioning system that relates in particular to a kind of oil eliminator and comprise it.
Background technology
The effect of oil eliminator is that the lubricating oil in the high steam that refrigeration compressor is discharged separates, to ensure that air-conditioning system moves safely and efficiently.The oil eliminator of air-conditioning refrigeration system of the prior art is not generally with filter, and oil return pipe is generally arranged in the bottom of oil eliminator.For example, Chinese patent literature CN201748726U open a kind of " oil eliminator ", shown in Figure 1, comprise tank body 100, air inlet pipe 200, blast pipe 300, screen pack 500 and oil return pipe 400, screen pack 500 is fixed on the middle and lower part of tank body 100 by support, tank body 100 inside are divided into upper and lower both sides, insert from the bottom of tank body 100 one end of oil return pipe 400, air inlet pipe 200 is inserted along tank body 100 tops, and extend the upside of screen pack 500, insert from the top of tank body 100 lower end of blast pipe 300, and extend to its downside through screen pack 500.At least there is defect in the oil eliminator of this patent: 1. air inlet pipe and blast pipe lay respectively at the both sides of screen pack, therefore this screen pack mainly plays the effect that improves oily separative efficiency, but the while is positioned at because the high-speed gas of the discharge of tracheae can stir oil and the impurity that filter screen goes out, impel impurity to enter tank base with fluid, and then may cause oil return system to stop up, affect the normal work of air-conditioning system; 2. oil return pipe is arranged at the bottom of tank body, and the impurity in fluid likely can enter oil return pipe, causes line clogging; 3. screen pack is arranged in tank body, need to weld in tank interior, causes fluid to be secondary polluted.
To sum up, the oil eliminator of this type of air-conditioning system, in the time carrying out oil separation, can cause the impurity of air-conditioning system to accumulate in the inside of oil eliminator, and the oil of then separating with oil eliminator is got back to system by oil return pipe, easily causes system oil return blockage.
In prior art, also there is the oil eliminator with filter, generally filter is placed on tracheae.For example, Chinese patent literature CN102654336A open a kind of " oil eliminator ", shown in Figure 2, this oil eliminator comprises cylindrical shell 101, ingress pipe 201, delivery line 301 and oil return pipe 401, delivery line 301 stretches in cylindrical shell 101, ingress pipe 201 is communicated with delivery line 301, and the bottom, lower end of delivery line 301 is provided with screen pack 501.The defect that the oil eliminator of this patent exists is: 1. screen pack is arranged on tracheae, can cause the resistance of refrigeration system to increase; 2. air inlet pipe is connected with blast pipe, and oily separative efficiency is not high.
To sum up, the oil filtering structure of this type of oil eliminator can cause the resistance of refrigeration system to increase, and affects the normal work of air-conditioning system.
On the whole, there is above defect in the oil eliminator of prior art, necessary making improvements.
