Abstract

The utility model discloses a pressure release starting drive of refrigerating system compressor relates to refrigeration plant technical field. The main technical characteristics are that the exhaust port of the compressor (1) is connected with one end of a one-way valve, the other end of the one-way valve is connected with a high-pressure area B of the refrigeration system, one end of an electromagnetic valve is connected with a copper pipe between the exhaust port of the compressor and the one-way valve, and the other end of the electromagnetic valve is connected with a low-pressure area A of the refrigeration system and an air suction port of the compressor. The starting circuit is suitable for central air conditioners, household air conditioners and refrigeration systems, has the advantages that the starting under pressure is realized by the starting circuit, the refrigeration systems 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 refrigeration system compressor
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, the refrigeration system of 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. 1~3) is by compressor (1), magnetic valve (2,4), check valve (3) is formed, this pressure release starting drive is the pressure release starting drive that connects compressor on the compressor in refrigeration system, compressor is opened under situation with pressure, stop, its structure is connected with two kinds of forms, first kind of version (Fig. 1) is to be connected on the end of check valve (3) with the exhaust outlet of copper pipe with compressor (1), the other end of check valve (3) connects refrigeration system high pressure district B, be connected on the exhaust outlet and the copper pipe between the check valve (3) of compressor (1) with the end of copper pipe, constitute on the low-pressure area A of the other end of magnetic valve (2) connection refrigeration system and the air entry of compressor (1) magnetic valve (2).Its course of work is: after compressor (1) was shut down, magnetic valve (2) energising was connected, and the air entry of compressor (1) and the low-pressure area A of refrigeration system are connected.Between the exhaust outlet of compressor (1) and refrigeration system high pressure district B because check valve (3) is arranged, the gases at high pressure of refrigeration system can not be got back to the exhaust outlet of compressor (1), at this moment, the exhaust ports of compressor (1) can normally start once more in low-pressure state, after the startup, magnetic valve (2) outage is closed, and the exhaust port pressure of compressor (1) raises, after reaching higher-pressure region pressure, gas enters higher-pressure region B by check valve (3), has realized that the band of compressor is pressed startup.
Second kind of version (Fig. 2) is to be welded on the position of check valve (3) with magnetic valve (4), is connected on the end of magnetic valve (4) with the exhaust outlet of same copper pipe with compressor (1).The other end of magnetic valve (4) is connected on the refrigeration system high pressure district B, be connected on the exhaust outlet and the copper pipe between the magnetic valve (4) of compressor (1) with the end of copper pipe with magnetic valve (2), the other end of magnetic valve (2) is connected on the air entry of refrigeration system low-pressure area A and compressor (1) and constitutes.Its course of work is: after compressor (1) is shut down; magnetic valve (4) outage is closed; magnetic valve (2) energising is connected, and the air entry of compressor (1) and refrigeration system low-pressure area A are connected, and the exhaust ports of compressor (1) is in low-pressure state; can normally start once more; after the startup, magnetic valve (2) cuts out, and magnetic valve (4) energising is connected; the exhaust outlet of compressor (1) is just connected with refrigeration system high pressure district B, has realized that the normal pressure of compressor (1) starts.
The effect of the pressure release starting drive of the utility model refrigeration system compressor is compared with prior art: just can realize that the band pressure starts because this device has been installed on the compressor of prior art refrigeration system, and can constitute the refrigeration system of a plurality of compressor parallels, 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 first kind of version figure of the utility model;
Fig. 2 is second kind of version figure of the utility model;
Fig. 3 is that first kind of version of the utility model is applied to the structure chart that prior art is made single-phase five cabinet air conditioner refrigeration systems.Constitute by evaporimeter (9), compressor (10), cross valve (6), capillary or expansion valve (7) and condenser (8).
The embodiment of the pressure release starting drive of the utility model refrigeration system compressor is: the 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. 3, with first kind of version is that compressor (1) employing prior art products standard condition refrigerating capacity is 5kW, the standard condition refrigerating capacity of compressor (10) is 7kW, adopt the magnetic valve (2) of prior art products, requiring diameter is φ 4mm, it is φ 8mm that check valve (3) requires diameter, it is to produce welding evaporimeter (9), cross valve (6) with copper pipe and prior art products that its structure connects, compressor (10), capillary or expansion valve (7) and condenser (8) are made refrigeration system.The pressure release starting drive of compressor is to be welded on the end of check valve (3) with the exhaust outlet of copper pipe with compressor (1), be welded on the higher-pressure region B of refrigeration system with the other end of copper pipe with check valve (3), the other end that magnetic valve (2) is welded on magnetic valve (2) on the exhaust outlet of compressor (1) and the copper pipe between the check valve (3) with copper pipe is welded on copper pipe on the air entry of the low-pressure area A of refrigeration system and compressor (1) and constitutes.
The embodiment of the pressure release starting drive of second kind of version compressor is identical with embodiment in the pressure release starting drive of first kind of version compressor, wherein magnetic valve (4) is used prior art products, requiring diameter is φ 8mm, is welded on the position that replaces check valve (3) in first kind of version with copper pipe to constitute.
