Abstract
The utility model relates to a one-driven-multiunit air conditioner. Indoor machines are mutually connected in parallel and are communicated with an outdoor machine heat exchanger and a compressor then. The utility model is characterized in that the refrigerant inlet end of each indoor machine is respectively communicated with an electronic expansion valve in series; the compressor comprises a variable capacity compressor and a constant speed compressor which are mutually connected in parallel. The output power of the compressor of the utility model can vary following the variation of power required by indoor machines. The utility model has small power loss and saves electricity.
Description
The utility model relates to an a kind of one driven multiple air conditioner.
The compressor capacity of an existing one driven multiple air conditioner is specified constant.When only opening the part indoor set, the power output of compressor is specified constant, and at this moment, the power output of compressor produces the loss of the energy greater than the required value of each indoor set.
The purpose of this utility model provides a kind of can change with the indoor set power demand and one driven multiple air conditioner that mate mutually of power output of compressor.
In order to achieve the above object, the utility model is achieved in that each indoor set is connected in series connection with off-premises station heat exchanger and compressor mutually and after connecing again; It is characterized in that: the refrigerant arrival end at each indoor set is connected in series connection one electric expansion valve respectively; Compressor comprises variable ability compressor and constant speed compressor, and they mutually and connect.Compressor comprises compressor and two constant speed compressors of a variable ability, and they mutually and connect.
The utility model compared with prior art has following advantage:
1, the power output of compressor can be with the variation of indoor set power demand;
2, power attenuation is little, using electricity wisely.
Fig. 1 is a connection diagram of the present utility model.
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, each indoor set (6), (7), (8) are connected in series connection with off-premises station heat exchanger (4) and compressor mutually and after connecing again; Refrigerant arrival end in each indoor set (6), (7), (8) is connected in series respectively and is communicated with an electric expansion valve (9).Compressor in the middle of the utility model comprises the compressor (1) of a variable ability and two constant speed compressors (2), (3), and they are mutual and connect.Because compressor capacity can change, so its indoor set (6), (7), (8) can freely be opened, accomplish that really the indoor and outdoor ability freely mates, avoid in the past that the multi-split air conditioner compressor capacity can not change, cause the drawback of a large amount of power consumptions of compressor when only opening the part indoor set.During work, refrigerant flows to and is: compressor (1), (2), (3) → off-premises station heat exchanger (4) → each electric expansion valve (9) → each indoor set (6), (7), (8) → compressor (1), (2), (3).
Claims (2)
1, an a kind of one driven multiple air conditioner, each indoor set is connected in series connection with off-premises station heat exchanger and compressor mutually and after connecing again; It is characterized in that: the refrigerant arrival end in each indoor set (6), (7), (8) is connected in series respectively and is communicated with an electric expansion valve (9); Compressor comprises variable ability compressor and constant speed compressor, and they mutually and connect.
2, an one driven multiple air conditioner according to claim 1 is characterized in that: compressor comprises the compressor (1) of a variable ability and two constant speed compressors (2), (3), and they mutually and connect.
