Abstract
The present invention discloses a refrigerant flow regulation device in high-capacity air-conditioning system. It is characterized by that in air-conditioning refrigeration and heat production system are parallelly set a low-capacity electronic expansion valve and a capillary tube, in which two ends of parallelly-connected low-capacity electronic expansion valve and capillary tube are respectively connected into refrigerant flow path of air-conditioning system. Said invention adopts the parallel connection of low-capacity electronic expansion valve and capillary tube to control flow quantity of refrigerant.
Description
Technical field
The present invention relates to a kind of air conditioner refrigerating heating.Particularly relate to cold medium flux adjusting device in the high-capacity air conditioning system that a kind of cold medium flux is controlled well, cost is low.
Background technology
Generally speaking, the course of work of air-conditioner is as follows: compressor is with the refrigerant of the refrigerant boil down to high temp/high pressure state of gaseous state; The gaseous coolant of boil down to high temp/high pressure state is cooled in condenser; In expansion valve, again the refrigerant of cooling is converted into the refrigerant of low temperature/low-pressure state; In evaporimeter, by heat exchange, absorb evaporimeter heat on every side, thereby reduce the temperature of surrounding air.
For Saperated air conditioner: be arranged on the heat of evaporation that evaporimeter in the indoor set utilizes refrigerant, the temperature of surrounding air is descended, make the temperature of the position periphery that is provided with indoor set be lower than the temperature at other position.Be arranged on compressor and condenser in the off-premises station, the gaseous coolant via evaporimeter is converted to the refrigerant of high temp/high pressure state after, the operation of freezing.In order to improve the cooling effectiveness of refrigerant, in a side of off-premises station cooling fan and the drive motors that drives the cooling fan rotation are installed, make the low relatively force air of outside temperature pass through condenser, thus the cooling refrigerant.
Compressor from off-premises station is the refrigerant of low-temperature/high-pressure state through the refrigerant that condenser flows out, and needs in expansion valve, the refrigerant that cools off is converted into the refrigerant of low temperature/low-pressure state after, flow into again in the evaporimeter of indoor set, carry out heat exchange.
As shown in Figure 1, in the prior art, normally in 5 above large capacity conditioner streams, only adopt a big flow electric expansion valve 5 to be connected in the refrigerant flow 4, in order to the control cold medium flux.Particularly the alternative capillaries of big flow electric expansion valve that adopt are controlled cold medium fluxes more in the business air conditioner system.But big flow electric expansion valve cost is very high to be unfavorable for that whole air-conditioning system controls cost.
Summary of the invention
Technical problem to be solved by this invention is that cold medium flux adjusting device in the high-capacity air conditioning system that a kind of cold medium flux is controlled well, cost is low is provided.
The technical solution adopted in the present invention is: cold medium flux adjusting device in a kind of high-capacity air conditioning system, low capacity electric expansion valve and capillary in the air conditioner refrigerating heating, have been arranged in parallel, wherein, low capacity electric expansion valve that is in parallel and two ends capillaceous are connected in the refrigerant flow in the air-conditioning system.
The present invention need not be provided with the electronic expansion valve controls cold medium flux of big flow, but adopt capillary and low capacity electric expansion valve Parallel Control flow, making wherein, 30% cold medium flux flows through by electric expansion valve, 70% cold medium flux flows through by capillary module, reach and surpassed the effect of the electronic expansion valve controls cold medium flux of big flow fully, and reduced overall cost greatly, controlled the wider of flow simultaneously.

Fig. 1 is a cold medium flux adjusting device in the high-capacity air conditioning system of prior art;
Fig. 2 is a cold medium flux adjusting device in the high-capacity air conditioning system of the present invention.
Wherein:
1: low capacity electric expansion valve 2: capillary
3: connector a, b, c: gateway
The specific embodiment
Below in conjunction with the drawings and specific embodiments, describe cold medium flux adjusting device in the high-capacity air conditioning system of the present invention in detail.
As shown in Figure 2, cold medium flux adjusting device in the high-capacity air conditioning system is to be arranged in parallel low capacity electric expansion valve 1 and capillary 2 in the air conditioner refrigerating heating.Wherein, the low capacity electric expansion valve 1 that is in parallel and the two ends of capillary 2 are connected in the refrigerant flow in the air-conditioning system.
The two ends of described low capacity electric expansion valve 1 that is in parallel and capillary 2 are connected in the refrigerant flow in the air-conditioning system by two connectors 3 respectively, the end that connector 3 is connected with refrigerant flow is formed with a gateway a, and the other end that is connected with refrigerant flow is formed with gateway b that is connected with low capacity electric expansion valve 1 and the gateway c that is connected with capillary 2.
Also be formed with the connector that links to each other with two connectors 3 respectively on the low capacity electric expansion valve 1.
As above cold medium flux adjusting device in the high-capacity air conditioning system of structure, flow into the gateway a of a certain connector 3 when refrigerant after, wherein 30% refrigerant flows into low capacity electric expansion valve 1 through the gateway of this connector 3 b, 70% refrigerant flows into capillary 2 through the gateway of this connector 3 c, then, enter the gateway b of another connector 3 again from the refrigerant of low capacity electric expansion valve 1 outflow, enter the gateway c of this connector 3 again from the refrigerant of capillary 2 outflows, at last, from then on the gateway a of connector 3 flows in the refrigerant flow.Thereby, reach and surpassed the effect of the electronic expansion valve controls cold medium flux of big flow fully, and reduced overall cost greatly, control the wider of flow simultaneously.
