The utility model is suitable for central air conditioners, household air conditioners and refrigeration systems. The utility model has self load regulation, and achieves the goal that the compressor is started with pressure. The utility model has simple structure, and is favorable for the compressor to normally work.
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 is generally by evaporimeter; low-pressure area), one or more compressors and condenser (higher-pressure region) are formed, and 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, when requiring to start, all exist and to shut down the pressurize startup and be with the problem that starts difficulty of pressing at once 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, this pressure release starting drive is mounted on the compressor of refrigeration system, two or more compressors are started under situation with pressure, the purpose that starts difficulty with pressing can not occur.
The design of the pressure release starting drive of the utility model refrigeration system compressor (Fig. 1～2) is by compressor (1) buffer container (2), check valve (3), and magnetic valve (4) or capillary (4) are formed.Primary structure is connected with two kinds of forms: the pressure release starting drive that first kind of version is compressor is by compressor (1); buffer container (2); check valve (3); magnetic valve (4) is formed; it is to be connected on the buffer container (2) with the exhaust outlet of copper pipe with compressor (1) that its structure connects; buffer container (2) is connected on the end of magnetic valve (4) with copper pipe; the air inlet A that the other end of magnetic valve (4) is connected compressor (1) goes up (low-pressure area); buffer container (2) is connected on the end of check valve (3) with copper pipe; the other end of check valve (3) is connected the pressure release starting drive of higher-pressure region B last (condenser) formation the utility model refrigeration system compressor with copper pipe; its course of work is: at a plurality of compressor operatings or under the situation of energy saving of system pressurize; after compressor shutdown; the higher-pressure region will keep high pressure; low-pressure area will keep low pressure and magnetic valve (4) be opened during compressor shutdown high pressure gas in the buffer container (2) and make by magnetic valve (4) low-pressure area of releasing; and the gases at high pressure of higher-pressure region can not enter buffer container (2) by check valve (3); compressor (1) is shut down between back buffer container (2) maintenance low pressure compressor (1) porting does not like this have pressure differential; can normally start; starting the back is closed by compressor (1) control magnetic valve (4); after the gas pressure of buffer container (2) surpasses higher-pressure region pressure; the exhaust of compressor (1) enters the higher-pressure region by check valve, has realized the operate as normal of compressor (1).
Second kind of version of the present utility model is by compressor (1) buffer container (2); check valve (3); capillary (4) is formed; it is to be connected on the buffer container (2) with the exhaust outlet of copper pipe with compressor (1) that its structure connects; buffer container (2) is connected on the end of capillary (4) with copper pipe; be connected on the air inlet A (low-pressure area) of compressor (1) with the other end of copper pipe capillary (4); buffer container (2) is connected on the end of check valve (3) with copper pipe; the other end of check valve is connected the pressure release starting drive of higher-pressure region B last (condenser) formation the utility model refrigeration system compressor with copper pipe; its course of work is: at a plurality of compressor operatings or under the situation of energy saving of system pressurize; after compressor shutdown; the higher-pressure region will keep high pressure, and low-pressure area will keep low pressure.Gases at high pressure in the buffer container will be by the capillary low-pressure area of releasing, and higher-pressure region gas can not enter buffer container by check valve.Like this, after a period of time, buffer container will keep low pressure in compressor shutdown, when compressor starts once more, can simply not be with to press to start.And after buffer container (2) gas pressure surpassed higher-pressure region pressure, gas flowed to the higher-pressure region by check valve, has realized the operate as normal of compressor (1).
The effect of the pressure release starting drive of the utility model refrigeration system compressor is compared with prior art: since when this device being installed on the refrigeration system compressor just can having satisfied a plurality of compressor operating or needs refrigeration system is carried out under the situation of " energy-conservation " pressurize; after compressor shutdown; can carry out substep starts; self realizes Load Regulation; reach the purpose of smooth startup; overcome in the prior art; the compressor band is pressed and is started situation of difficult; solved the problem of compressor nonsynchronous initiation in the refrigeration system; have simple in structurely, help the effect of compressor operate as normal.
Fig. 1 is first kind of structure chart of the pressure release starting drive of the utility model refrigeration system compressor;
Fig. 2 is second kind of structure chart of the present utility model.
The embodiment of first kind of structure of the pressure release starting drive of the utility model refrigeration system compressor is: the refrigeration system of making the cabinet air-conditioner of single-phase five horsepowers of double-compressor with prior art, in order to reduce starting current, adopt two compressors to start step by step, and An Biaoben pressure release starting drive realize opening, stopping Load Regulation on a compressor.It is the compressor (1) that adopts prior art products, the requirement input power is 1.8KW, the standard condition refrigerating capacity is 5KW, adopt the buffer container (2) of prior art products, the requirement volume is 2000cc, adopt the magnetic valve (4) of an existing art product, requiring latus rectum is 4mm, adopt the check valve (3) of prior art products, be welded to connect on buffer container (2) with the exhaust outlet of copper pipe respectively compressor (1), buffer container (2) is welded to connect on an end of magnetic valve (4), the air inlet A that the other end of magnetic valve (4) is welded to connect at compressor (1) goes up (low-pressure area), buffer container (2) is welded to connect on an end of check valve (3), and the other end of check valve is welded to connect (condenser) formation on the B of higher-pressure region.
The embodiment of second kind of structure of the present utility model is a refrigeration system of making the cabinet air-conditioner of single-phase five horsepowers of double-compressor with prior art, it is the compressor (1) that adopts the prior art products of embodiment one, buffer container (2), check valve (3), adopting the prior art products internal diameter is the capillary (4) of 1.6mm, with copper pipe buffer container (2) is welded to connect on an end of capillary (4) respectively, the air inlet A that the other end capillaceous is welded to connect at compressor (1) goes up (low-pressure area), and it is in connected mode and embodiment one identical formation.
