Description

The detachable air conditioner that a kind of indoor and outdoor unit connects fast
Technical field
The utility model relates to a kind of air-conditioner, and the detachable air conditioner that particularly a kind of indoor and outdoor unit connects fast belongs to the improvement technology that has detachable air conditioner now.
Background technology
Detachable air conditioner will couple together indoor units and outdoor unit with the indoor and outdoor machine tube connector when mounted, could form the complete air-conditioning system operate as normal of a cover.Air-conditioner generally fills good cold-producing medium in outdoor unit when dispatching from the factory, drain the air in indoor set and the tube connector when mounted, and air-conditioner is normally moved.Existing detachable air conditioner includes outdoor unit, two tube connectors, indoor units, there are two stop valves to be connected in the wherein outdoor unit with two tube connectors, there are two pipe joints to be connected in the indoor units, make indoor and outdoor machine connect into closed closed circuit by two tube connectors with two tube connectors.The air of draining during installation in indoor units and the tube connector mainly contains following several method.First kind is with fill good cold-producing medium emptying gas in advance in outdoor unit, earlier two pipe joints in two tube connectors and the indoor units are connected during installation, a stop valve and a tube connector in the outdoor unit connect, open this stop valve then, allow cold-producing medium in the outdoor unit from this stop valve tube connector of flowing through successively, pipe joint, enter indoor set, flow out through another pipe joint and another tube connector by indoor set then, after cooled dose of the air of pipe to be connected and indoor units the inside blows out, again another tube connector and another stop valve are connected, open the connection that two stop valves are promptly finished the indoor and outdoor unit at last fully; Second kind is to drain air with the cold-producing medium in the refrigerant cylinder, earlier two pipe joints in two tube connectors and the indoor units are connected during installation, article one, a stop valve in tube connector and the outdoor unit connects, there is an interface to be connected at this stop valve place with refrigerant cylinder, open the valve of refrigerant cylinder, allow the cold-producing medium that flows out in the refrigerant cylinder flow to tube connector through pipe joint from this stop valve, indoor set, another pipe joint and another tube connector flow out, after cooled dose of the air of pipe to be connected and indoor units the inside blows out, again another tube connector and another stop valve are connected, open the connection that two stop valves are promptly finished the indoor and outdoor unit at last fully; The third is an air of taking the inside with vavuum pump away, during installation, two tube connectors respectively with outdoor unit in two stop valves and two pipe joints in the indoor units connect, a stop valve place has an interface to be connected with vavuum pump therein, open vavuum pump, Li Mian air is extracted out by vavuum pump after a period of time, and vacuum reaches and disconnects being connected of vavuum pump and this stop valve after the requirement, opens the connection that two stop valves are promptly finished the indoor and outdoor unit fully at last.
Three kinds of above installation methods respectively have pluses and minuses.First method is the quickest, but can only be applicable to the cold-producing medium that constitutes by single composition, such as R22 commonly used, but the refrigerant amount that this method ejects can only be grasped by installation personnel oneself, inaccurate, the quality of emptying gas also not necessarily is guaranteed, and the cold-producing medium of releasing is wasted, also pollute the environment, ozone layer is had destruction.Second method is also than faster, but require the band refrigerant cylinder when installing, also can only be applicable to the cold-producing medium that constitutes by single composition, such as R22 commonly used, the quality of emptying gas also like that not necessarily is guaranteed with first method, and the cold-producing medium of releasing is wasted, and also pollutes the environment, and ozone layer is had destruction.The third method is applicable to various cold-producing mediums, and vacuum quality is guaranteed, and does not also have contaminated environment, and ozone layer is not had destruction, and shortcoming is that installation personnel will be with vavuum pump, and the time that vacuumizes is long, and operating efficiency is lower.
The utility model content
The purpose of this utility model is intended to overcome the shortcoming of prior art, the detachable air conditioner that provides a kind of simple and reasonable, function and the duplicate indoor and outdoor unit of common tube connector to be connected fast, this air-conditioner goes for various cold-producing mediums, installation rate is fast, non-environmental-pollution during installation is saved erecting tools.
The technical scheme that realizes the utility model purpose is: the utility model includes outdoor unit, two tube connectors and indoor units, two stop valves are arranged in the wherein outdoor unit, article two, an end of tube connector is fixedlyed connected with indoor set, article two, the other end of tube connector is respectively equipped with stop valve, and the stop valve on two tube connectors is connected with stop valve in the outdoor unit by pipe joint respectively.
One end and the indoor set of above-mentioned two tube connectors is fixedly connected as welding or pipe joint is connected.
The utility model is before dispatching from the factory, and outdoor unit and indoor units fill good cold-producing medium respectively, and the cold-producing medium total amount of indoor units and outdoor unit is that this cover air-conditioner moves needed refrigerant amount.
The beneficial effects of the utility model are: directly the stop valve on two tube connectors is connected by the stop valve in pipe joint and the outdoor unit respectively during installation, open four stop valves on tube connector and the outdoor unit then fully, just finished the connection of indoor and outdoor machine, owing to all be cold-producing medium inside indoor set and the tube connector when this air-conditioner is installed, so do not need emptying gas, also unnecessary band refrigerant cylinder or vavuum pump, saved erecting tools, saved the set-up time, saved the cold-producing medium that is used for emptying gas, and when having stopped to install to the pollution of environment.
