Abstract
The invention discloses a circulating system for air conditioners, which comprises a compressor, a condenser, a supercooled section, throttles and an evaporator. One end of the condenser communicates with the compressor via a pipeline and the other end thereof communicates with a liquid vessel via a pipeline which is provided with a throttle and a one-way valve in parallel arrangement. The liquid vessel communicates with a port of the supercooled section via a pipeline which is provided with a solenoid valve. The port of the supercooled section further communicates with the liquid vessel via a pipeline which is provided with a throttle and a one-way valve in series arrangement. The throttled communicate with the one-way valves via pipelines. The other port of the supercooled section communicates with the compressor and the evaporator respectively via parallel pipelines provided with one-way valves. The supercooled section can provide supercooling function during refrigeration and also can serve as evaporation section during heating to increase the heating effect.
Description
Technical field
The present invention relates to a kind of air-conditioning equipment, specifically a kind of air conditioner circulating system.
Background technology
In the present air-conditioner unit, many air-cooled condensers all are provided with super cooled sect, and the purpose of super cooled sect is to keep liquid condition before making cold-producing medium enter evaporimeter, overcome and prolong the defective that the journey resistance causes cold-producing medium to evaporate in advance, improve refrigeration.When heating, the liquid of HTHP will pass through throttle part through behind the super cooled sect earlier again, evaporates in heat exchanger then, and super cooled sect does not participate in evaporation, has caused the waste of equipment.
Summary of the invention
In order to overcome above-mentioned technical problem, the invention provides a kind of air conditioner circulating system, it can be converted into evaporator section with super cooled sect when heating, increased the disengagement area when heating.
The present invention for the technical scheme that overcomes above-mentioned technical problem employing is: a kind of air conditioner circulating system, comprise compressor, condenser, super cooled sect, flow controller and evaporimeter, one end of condenser is connected with compressor by pipeline, the other end is connected with reservoir by the pipeline that is arranged in parallel flow controller and check valve, described reservoir is connected with a port of super cooled sect by the pipeline that is provided with magnetic valve, this port of super cooled sect also is connected with reservoir by the pipeline that is connected with throttling arrangement and check valve, be connected with evaporimeter by pipeline between throttling arrangement and the check valve, the another port of super cooled sect is connected with compressor and evaporimeter respectively by the pipeline that is provided with check valve of parallel connection.
Above-mentioned flow controller adopts electric expansion valve.
The both sides of above-mentioned flow controller are provided with filter.
Above-mentioned throttling arrangement adopts capillary, is in series with filter between throttling arrangement and check valve.
The invention has the beneficial effects as follows: super cooled sect changes into evaporator section when heating, increased disengagement area, has improved heating effect; As the effect of super cooled sect, improved the purpose of heating effect in the time of can realizing heating again as evaporator section when both can be implemented in refrigeration.
Description of drawings
Fig. 1 is the johning knot composition of prior art;
Fig. 2 is a johning knot composition of the present invention.
The present invention will be described below in conjunction with accompanying drawing:
The specific embodiment
As shown in Figure 2, a kind of air conditioner circulating system, comprise the compressor (not shown), condenser 1, super cooled sect 2 and evaporimeter (not shown), one end of condenser 1 is connected with compressor by pipeline, the other end is connected with reservoir 5 by the pipeline that is arranged in parallel electric expansion valve 3 and check valve 4, described reservoir 5 is connected with a port 21 of super cooled sect 2 by the pipeline that is provided with magnetic valve 6, this port 21 of super cooled sect 2 also is connected with reservoir 5 by the pipeline that is connected with capillary 7 and check valve 8, be connected with evaporimeter by pipeline between capillary 7 and the check valve 8, the another port 22 of super cooled sect 2 is connected with compressor and evaporimeter respectively by the pipeline that is provided with check valve 9 and 10 of parallel connection.
The pipeline of above-mentioned electric expansion valve 3 both sides is provided with filter 11.
Be provided with filter 12 between above-mentioned capillary 7 and the check valve 8.
Operation principle of the present invention is: when refrigeration, the high temperature and high pressure gas that comes out from compressor carries out condensation through condenser 1, enter reservoir 5 by electric expansion valve 3 and check valve 4 then, enter super cooled sect 2 by magnetic valve 6 then, this moment, magnetic valve 6 was in open mode, flowed out after check valve 10 flows to evaporimeter from super cooled sect 2; When heating, the liquid major part of HTHP enters reservoir 5 by check valve 8, entering heat exchanger 1 through electric expansion valve 3 then evaporates, the fraction high temperature high pressure liquid enters super cooled sect through capillary 7 and evaporates, enter compressor by check valve 9 then, realize that super cooled sect is transformed into the purpose of evaporator section.When heating, magnetic valve 6 is in closed condition.
Certainly, protection scope of the present invention is not limited to the foregoing description, so long as those of ordinary skill in the art is through creatively improving, and just should be within protection scope of the present invention.
