Abstract
The utility model discloses a pressure release starting drive of refrigerating system compressor relates to refrigeration plant technical field. The main technical characteristic is that the air outlet of the compressor (1) is connected with the a end of the electromagnetic three-way valve, the B end of the electromagnetic three-way valve is connected with the high-pressure area B of the refrigerating system, and the C end of the electromagnetic three-way valve is connected with the air suction port of the compressor and the low-pressure area A of the refrigerating system. The starting device has the advantages that the starting under pressure is realized, a refrigeration system with a plurality of compressors connected in parallel can be formed, the plurality of compressors are asynchronously started and stopped, the problems of large starting current and difficulty in starting under pressure in the prior art are solved, the structure is simple, and the starting effect of the compressors is facilitated.
Description
The pressure release starting drive of the utility model refrigeration system compressor relates to technical field of refrigeration equipment, is applicable to central air-conditioning, in domestic air conditioning and the refrigeration system thereof.
At present, refrigeration system of the prior art, generally by evaporimeter, cross valve, capillary or expansion valve, one or more compressors and condenser are formed.Its weak point is after compressor shutdown; normally after the air pressure of higher-pressure region and low-pressure area reaches natural equilibrium; restart again; but sometimes; when people need start after shutdown again at once; perhaps, require substep to start one or more compressors, all exist band and press the problem that starts difficulty for refrigeration system is carried out " energy-conservation ".
The purpose of this utility model provides a kind of pressure release starting drive of refrigeration system compressor, and this pressure release starting drive is installed on the compressor of refrigeration system, and compressor is normally started under situation with pressure, reaches the purpose that compressor is started at any time.
The design of the pressure release starting drive of the utility model refrigeration system compressor (Fig. 1～2) is by compressor (1), and three-way solenoid valve (2) is formed.This device is the pressure release starting drive that connects compressor on the compressor in refrigeration system, can make compressor start and stop under situation with pressure, it is a end that the exhaust outlet of compressor (1) is connected three-way solenoid valve (2) with copper pipe that its structure connects, the b end of three-way solenoid valve (2) connects refrigeration system high pressure district B, and air entry and refrigeration system low-pressure area A that the C end of three-way solenoid valve (2) connects compressor (1) constitute.Its course of work is: after compressor (1) is shut down; three-way solenoid valve (2) energising; a, C termination are led to, and the air entry of compressor (1) and refrigeration system low-pressure area A connect, and the exhaust ports of compressor (1) is in low-pressure state; just can normally start once more; after compressor (1) starts, three-way solenoid valve (2) outage, a, b termination are led to; the exhaust outlet of compressor (1) and refrigeration system high pressure district B connect, and have realized that the band of compressor is pressed startup.
The effect of the pressure release starting drive of the utility model refrigeration system compressor is compared with prior art: just can realize with the pressure startup and can constitute the refrigeration system of a plurality of compressor parallels because this device has been installed on the compressor of prior art refrigeration system, the nonsynchronous start and stop operation of a plurality of compressors, thereby realized the Load Regulation of refrigeration system, also realized reducing the purpose of starting current, it is big to have overcome in the prior art starting current, band is pressed the shortcoming that starts difficulty and can not realize Load Regulation, have simple in structurely, help the effect of compressor start.
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is that the utility model is applied to the structure chart that prior art is made single-phase five cabinet air conditioner refrigeration systems, and by evaporimeter (6), compressor (7), cross valve (3), capillary or expansion valve (4), condenser (5) constitutes.
The embodiment of the pressure release starting drive of the utility model refrigeration system compressor is a cabinet air conditioner of making single-phase five horsepowers of double-compressor with prior art, in order to reduce starting current and to carry out Load Regulation, adopt two compressor nonsynchronous initiation operations as Fig. 2, it is 5kW that compressor (1) adopts prior art products standard condition refrigerating capacity, the standard condition refrigerating capacity of compressor (7) is 7kW, select the three-way solenoid valve (2) of prior art products for use, requiring diameter is φ 8mm, it is to produce welding evaporimeter (6) with copper pipe and prior art products that its structure connects, cross valve (3), compressor (7), capillary or expansion valve (4) and condenser (5) are made refrigeration system, the pressure release starting drive of compressor is a end that the exhaust outlet of compressor (1) is welded on three-way solenoid valve (2) with copper pipe, the b end of three-way solenoid valve (2) is welded on the refrigeration system high pressure district B, and air entry and refrigeration system low-pressure area A that the C of three-way solenoid valve (2) end is welded on compressor (1) go up formation.
Claims (1)
1, a kind of pressure release starting drive of refrigeration system compressor, by evaporimeter, cross valve, capillary or expansion valve, compressor and condenser are formed refrigeration system, it is characterized in that the exhaust outlet of compressor (1) is connected a end of three-way solenoid valve (2), the b end of three-way solenoid valve (2) connects refrigeration system high pressure district B, and air entry and refrigeration system low-pressure area A that the C end of three-way solenoid valve (2) connects compressor (1) upward constitute.
