Abstract
The utility model relates to an inner machine switching device for three-pipe heating recovery air conditioner system, comprising a four-way valve (STN), wherein, the four-way valve (STN) comprises an end D, an end A connected with a high pressure pipe (H), an end B connected with an inner machine (AN) and an end C connected with an outer machine via a low pressure pipe (L), while a capillary tube (M1) is connected between the end D and the end C. The utility model employs the structure of the four-way valve, which makes the traditional inner machine of the air conditioner obtain versatility in the three-pipe heat recovery air conditioner system. The utility model has the advantages of smart design and good performance while it is convenient and practical to use.
Description
Technical field
The utility model is a kind of interior machine switching device shifter of three-pipe heating and reclaiming air-conditioning system, belongs to the innovative technology of the interior machine switching device shifter of three-pipe heating and reclaiming air-conditioning system.
Background technology
At present, three-pipe heating and reclaiming air-conditioning system is a kind of novel multi-split air conditioner, has realized that not only machine freezes and heat-production functions simultaneously in the multi-split air conditioner, machine realization heat-production functions in other part when can also realize making the interior mechanism of part cold.Traditional air-conditioning internal machine has only two interfaces, it is the refrigerant entrance and exit, if do not change the structure of machine in the tradition, machine is connected with the outdoor machine of air-conditioner system of three control in the tradition so, just need a switching device shifter realize in the switching of the cold and heating mode of mechanism.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of structure that can not change traditional air-conditioning internal machine is provided, makes traditional air-conditioning internal machine have the interior machine switching device shifter of the three-pipe heating and reclaiming air-conditioning system of versatility in three-pipe heating and reclaiming air-conditioning system.
Structural representation of the present utility model as shown in Figure 1, comprise cross valve, wherein cross valve comprises that D end, the A that the is connected end with high-voltage tube, the B end that is connected with interior machine, the C that is connected with outer machine by low-voltage tube hold, and wherein D holds and C is connected with capillary (M1) between holding.
The utility model switching device shifter adopts the cross valve structure, and the structure that can not change traditional air-conditioning internal machine makes traditional air-conditioning internal machine also can have versatility in three-pipe heating and reclaiming air-conditioning system.The utility model is that a kind of design is ingenious, function admirable, the interior machine switching device shifter of convenient and practical three-pipe heating and reclaiming air-conditioning system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment:
The utility model structure as shown in Figure 1, comprise cross valve STN, wherein cross valve STN comprises D end, the A that the is connected end with high-voltage tube H, the B end that is connected with interior machine AN, passes through the C end that low-voltage tube L is connected with outer machine, wherein is connected with capillary M1 between D end and the C end.
When the utility model uses, when interior machine is in refrigerating state, outer machine refrigerant machine evaporation and heat-exchange in therefrom pressure pipe M flows to, this moment, cross valve was in power-down state, A and D conducting, B and C conducting are got back to low-voltage tube L by B to C through the refrigerant behind the interior machine evaporation and heat-exchange; When interior machine is in the state of heating, the refrigerant of outer machine HTHP is delivered to interior machine by high-voltage tube H, and this moment, cross valve was in power-up state, C and D conducting, A and B conducting, mechanism heat in refrigerant is flowed to by A to B, pressure pipe M the refrigerant that comes out from interior machine is got back to.Thereby realized switching cold, the heating operation pattern of interior mechanism with cross valve.
Claims (1)
1, a kind of interior machine switching device shifter of three-pipe heating and reclaiming air-conditioning system, it is characterized in that comprising cross valve (STN), wherein cross valve (STN) comprises D end, the A that the is connected end with high-voltage tube (H), the B end that is connected with interior machine (AN), passes through the C end that low-voltage tube (L) is connected with outer machine, wherein is connected with capillary (M1) between D end and the C end.
