Abstract
There is the air-cooled cold wind unit preventing refrigerant migration, belong to technical field of central air, be specifically related to a kind of air cooler of winter refrigeration.Arrange magnetic valve between the device for drying and filtering of indoor set and expansion valve, the liquid trap of indoor set is connected with device for drying and filtering by indoor liquid pipe, and liquid trap is connected with the outdoor liquid pipe of off-premises station by tube connector, stop valve, and outdoor liquid pipe arranges check valve.The utility model prevents refrigerant migration device by employing; air-conditioner set normally being run at low ambient temperatures, when air-conditioner set is because avoiding when certain reason is shut down occurring report high voltage fault, avoiding producing liquid hit phenomenon; reach the effect of unit frequent starting, reach energy-saving effect simultaneously.
Description
Technical field
The utility model belongs to technical field of central air, is specifically related to a kind of air cooler of winter refrigeration.
Background technology
Existing air-conditioner set, is applicable to cooling in summer substantially.This kind of unit does not structurally have the special device preventing refrigerant migration, and at running refrigerating in winter, when shutting down because of certain reason, because environment temperature is low, cold-producing medium can move to off-premises station, and cold-producing medium can concentrate at off-premises station; When compressor starts again, because cold-producing medium major part moves to off-premises station finned heat exchanger, cold-producing medium is made to be difficult to condensation for the moment, to offer a high price instantaneously pressure, can be there are some cold-producing mediums in low side evaporator simultaneously, when again starting shooting, has little time and evaporator heat exchange, directly can enter compressor, cause liquid hit phenomenon.
Summary of the invention
The object of utility model is to provide a kind ofly has the air-cooled cold wind unit preventing refrigerant migration, to solve prior art Problems existing.
The utility model is primarily of indoor set and off-premises station composition, solving the technical scheme that its technical problem adopts is: arrange magnetic valve between the device for drying and filtering of indoor set and expansion valve, the liquid trap of indoor set is connected with device for drying and filtering by indoor liquid pipe, liquid trap is connected with the outdoor liquid pipe of off-premises station by tube connector, stop valve, and outdoor liquid pipe arranges check valve.
Good effect of the present utility model is adopted to be prevent refrigerant migration device by adopting; air-conditioner set is normally run at low ambient temperatures; when air-conditioner set is because avoiding when certain reason is shut down occurring report high voltage fault; avoid producing liquid hit phenomenon; reach the effect of unit frequent starting, reach energy-saving effect simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the utility model structural representation;
1 indoor set, 2 expansion valves, 3 indoor liquid pipes, 4 magnetic valves, 5 devices for drying and filtering, 6 liquid traps, 7 tube connectors, 8 stop valves, 9 check valves, 10 outdoor liquid pipes, 11 off-premises stations in figure.
Detailed description of the invention
As shown in the figure: between the device for drying and filtering 5 of indoor set 1 and expansion valve 2, magnetic valve 4 is installed, the liquid trap 6 of indoor set 1 is connected with device for drying and filtering 5 by indoor liquid pipe 3, liquid trap 6 is connected with the outdoor liquid pipe 10 of off-premises station 11 by tube connector 7, stop valve 8, and outdoor liquid pipe 10 arranges check valve 9.
The structure of expansion valve, device for drying and filtering, indoor liquid pipe, outdoor liquid pipe is same as the prior art.
Duty describes: when unit runs at low ambient temperatures, during due to certain factor compressor emergency shutdown, cold-producing medium can move to the off-premises station finned cooler that temperature is lower, the setting of fin Outlet check valves, block the movement of cold-producing medium, while shutting down, magnetic valve also cuts out, and prevents cold-producing medium to move to low pressure evaporator side, makes cold-producing medium concentrate in liquid trap; When unit is started shooting again, magnetic valve is opened, and cold-producing medium enters low-pressure side from liquid trap by choke valve rapidly, carries out heat exchange simultaneously, avoid in finned evaporator and there is a large amount of cold-producing medium with evaporation side finned heat exchanger, makes unit produce liquid hit phenomenon.Discharge high temperature and high pressure gas after compression, owing to not storing a large amount of cold-producing medium in condenser, so the cold-producing medium entering condenser can condensation in time, enter liquid trap, solve pressure failure problems of offering a high price.
Claims (1)
1. one kind has the air-cooled cold wind unit preventing refrigerant migration, primarily of indoor set and off-premises station composition, it is characterized in that: between the device for drying and filtering of indoor set and expansion valve, magnetic valve is set, the liquid trap of indoor set is connected with device for drying and filtering by indoor liquid pipe, liquid trap is connected with the outdoor liquid pipe of off-premises station by tube connector, stop valve, and outdoor liquid pipe arranges check valve.
