Abstract
The utility model discloses an air conditioner heat exchanger system, this system include heat exchanger, be connected with electronic expansion valve and subcooling pipe on heat exchanger's the refrigerant pipe, the last parallelly connected check valve that has of electronic expansion valve. The utility model discloses an air conditioner heat exchanger system can be more direct, more accurate regulation superheat degree, reaches the purpose that improves greenhouse heat transfer volume and efficiency.
Description
Technical Field
The utility model relates to a refrigeration plant technical field, in particular to air conditioner heat exchanger system.
Background
In the prior art, in order to improve the cooling capacity of an air conditioning system, a plurality of supercooling pipes, namely a supercooling degree section, are generally added to a refrigerant pipe at the bottom of an outdoor heat exchanger, and an electronic expansion valve is connected behind the supercooling section for throttling. This kind increases the coldness section in order to improve cold room ability at outdoor heat exchange bottom refrigerant pipe, connects electronic expansion valve's heat exchange structure behind the supercooling section, though the cold room can play certain throttling action, but connects the electronic expansion valve for heating behind the supercooling section, has certain defect: when the air conditioner is used for cooling, the refrigerant passing through the supercooling section still can be throttled and decompressed when encountering the fully-opened air conditioner electronic expansion valve, so that certain energy loss is caused, and the whole supercooling function cannot be fully exerted; when the house is warmed, the refrigerant firstly passes through the electronic expansion valve to control the air suction superheat degree, and then is redistributed to heat exchange for heat exchange through the heat exchange of the supercooling degree section at the bottom, so that the superheat degree adjustment cannot be directly applied to the outdoor heat exchanger, and certain influence is caused on the performance of the outdoor heat exchanger.
SUMMERY OF THE UTILITY MODEL
The utility model provides an air conditioner heat exchanger system to solve the defect of prior art air conditioning heat exchanger system.
In order to solve the technical problem, the technical scheme of the utility model is that:
an air-conditioning heat exchanger system comprises a heat exchanger, wherein an electronic expansion valve and a supercooling pipe are connected to a refrigerant pipe of the heat exchanger, and a one-way valve is connected to the electronic expansion valve in parallel.
Further: and filters are respectively arranged at two ends of the electronic expansion valve.
By adopting the technical scheme, the electronic expansion valve and the supercooling pipe are arranged, the one-way valve is arranged, and the electronic expansion valve is arranged between the supercooling pipes of the heat exchanger, so that the supercooling of a cold room can be ensured, the superheat degree of a warm room can be accurately and directly adjusted, and the performance of the warm room can be improved.
Drawings
Fig. 1 is a schematic structural view of an air-conditioning heat exchanger system according to the present invention;
in the figure, 1 is a heat exchanger, 2 is an electronic expansion valve, 3 is a supercooling pipe, 4 is a one-way valve and 5 is a filter.
Detailed Description
The following description will further explain embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
An air-conditioning heat exchanger system comprises a heat exchanger 1, wherein an electronic expansion valve 2 and a supercooling pipe 3 are sequentially connected to a refrigerant pipe of the heat exchanger 1, and a one-way valve 4 is connected to the electronic expansion valve 2 in parallel. In addition, filters 5 are respectively arranged at two ends of the electronic expansion valve 2.
The low-temperature liquid is cooled by the cold pipe 3 and then enters the heat exchanger 1 from the electronic expansion valve 2, so that the superheat degree can be more directly and accurately adjusted, and the purposes of improving the heat exchange amount and the energy efficiency of a greenhouse are achieved.
The electronic expansion valve 2 is connected with the one-way valve 4 in parallel, and liquid flowing out of the heat exchanger 1 flows out through the electronic expansion valve 2 and the one-way valve 4, so that the pressure loss of the expansion valve 2 is reduced, the refrigerant flow is increased, and the performance of a cooling room can be improved.
The filters 5 are arranged at the two ends of the electronic expansion valve 2, so that impurities in the refrigerant can be filtered, and pipelines are prevented from being blocked.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
