Abstract
The utility model relates to an indoor unit of a split air conditioner. The indoor unit of a split air conditioner comprises a liquid pipe, a filter, a heat exchanger, an air pipe, a fan and a fan electromotor, wherein, an electronic expansion valve is arranged on the liquid pipe. A controller of the electronic expansion valve is arranged on an electric control panel of the indoor unit. The indoor electronic expansion valve replaces an outdoor capillary throttling element. Thus, a refrigerant flow can be actively regulated for adapting the variation of indoor heat load, simplifying control programs and enhancing system operation efficiency. For one machine with multiple products, the utility model has the advantages of mutually independent flow control between indoor units and simplification of the pipeline structure of an outdoor unit and system installation programs and has no order clash.
Description
The utility model relates to a kind of indoor set of detachable air conditioner.
At present, the air-conditioning product on the market generally all adopts capillary as restricting element, because the required capillary pipe length of refrigeration and the throttling of when operation system is different, heat pump type air conditioner also will be connected in series the check valve of being with assisted capillary behind capillary.Itself can not regulate refrigerant flow this restricting element, can only adapt to load variations passively among a small circle, has certain heat loss in addition, makes running efficiency of system be difficult to improve.The transducer air conditioning of Chu Xianing is made throttling control element with the electric expansion valve that is installed in the off-premises station in recent years, replaces the capillary section fluid element, has increased the control function.But drag the fecund product for one, need a plurality of electric expansion valves, if they all place off-premises station, then off-premises station all will carry out direct pipeline with each indoor set and is connected, make the pipeline configuration of off-premises station become quite complicated, also will increase a lot of valve members, the indoor set that drags is many more, and pipeline configuration is complicated more.
The purpose of this utility model is, overcomes the shortcoming of existing split-type air conditioner device restricting element, and a kind of simple in structure, the novel split-type air conditioner indoor set that can regulate, be convenient to control refrigerant flow is provided.
The purpose of this utility model is achieved through the following technical solutions: the composition of novel split-type air conditioner indoor set comprises liquid pipe, filter, heat exchanger, tracheae, fan, fan electromotor, it is characterized in that an electric expansion valve is installed on the liquid pipe, the electronic Expansion Valve Control device is made on this indoor set electric control panel.
The utility model is installed in electric expansion valve in the indoor split-type air conditioner, replace the capillary section fluid element in the off-premises station, not only overcome the defective of capillary-compensated, but also can control separately this indoor set refrigerant flow, active adjustment makes running efficiency of system be improved to adapt to the variation of indoor thermic load; Simultaneously, because the electronic Expansion Valve Control device is made on the electric control panel of each indoor set, make and come the control of each indoor set is relatively independent, save control signal and be sent to off-premises station is implemented control again to electric expansion valve program earlier, for one drag the fecund product, between each indoor set flow-control mutually independence, simplified control, not order conflict, the machine of open and close simultaneously is all unrestricted; In addition, can also simplify the pipeline structure of off-premises station and the installation procedure of system, off-premises station only needs liquid pipe and two pipe joints of tracheae, and the pipe arrangement between itself and each indoor set can be connected in parallel by corresponding joint.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model structural representation.
As shown in Figure 1, the composition of novel split-type air conditioner indoor set comprises liquid pipe 6, filter 1, heat exchanger 5, tracheae 7, fan 3, fan electromotor 4, an electric expansion valve 2 is installed on the liquid pipe 6, and the controller of electric expansion valve 2 is made on this indoor set electric control panel (not drawing among the figure).
The utility model is freezing or during heating operation, electric expansion valve plays throttling action on the one hand, on the other hand, the difference of indoor environment temperature and design temperature and the indoor heat exchanger outlet degree of superheat or degree of supercooling can be carried out corresponding adjusting to the aperture of electric expansion valve, make the refrigerant flow and the indoor thermic load that flow through this indoor set be complementary, thereby the system that makes can both be in duty preferably under the operating mode arbitrarily, improves the operational efficiency of system.
The structure of the utility model indoor set also helps defrosting when heating in system.Generally all be by the reversal valve commutation in the past, the cold-producing medium reverse flow, the direct inlet chamber external heat exchanger of compressor air-discharging defrosts, and can cause the bigger decline of indoor temperature, influences comfortableness.Restriction characteristic when the utility model can utilize the electric expansion valve standard-sized sheet, do not need the reversal valve action when defrosting, the electronic expansion valve opening of indoor set is reached maximum (not playing throttling action this moment substantially), the gas that compressor is discharged still arrives first indoor set, also has higher temperature after the preliminary condensation, the inlet chamber external heat exchanger is removed the frost layer of tying on its surface, so again, in defrost process, indoorly still keep the input of certain heat, do not have cold wind and blow out, temperature can not descend suddenly.
The utility model is simple in structure, and reliable operation can conveniently realize the independent control to environment of living in, the control accuracy height, amenity is good, the running efficiency of system height, be applicable to the split-type air conditioner unit of various types, especially be suitable as the indoor set of multi-split air conditioner.
