Abstract
The invention discloses an air conditioning system with a pressure relief function. The air conditioning system comprises a compressor, a condenser, an expansion valve, an evaporator and a gas-liquid separator. A pressure relief branch is arranged between an inlet pipe of the condenser and an inlet pipe of the evaporator, an electromagnetic valve is serially connected in the pressure relief branch, and turning on and turning off of the electromagnetic valve are staggered and synchronized with turning on and turning off of the compressor. Since the pressure relief branch is arranged between the inlet pipe of the condenser and the inlet pipe of the evaporator, a high-pressure refrigerant in the condenser can be quickly released into low-pressure refrigerant of the evaporator, pressure balance of a refrigerating system is quickly established, and pressure difference is prevented from existing in the system when the compressor is started again; meanwhile, diameter of the pressure relief branch is large, so that oil return of the refrigerating system is well guaranteed, and heat exchange effect of the system is improved; moreover, a pressure sensor is further arranged at the position of the electromagnetic valve, pressure relief information can be fed back to an air conditioning control system by the pressure sensor, and accordingly convenience is brought to the control system to adjust states of an air conditioner.
Description
Technical field
The present invention relates to a kind of air-conditioning system with decompression function.
Background technology
Because industrial air-conditioning device environment for use is special, appellative function is more, so the refrigerant system configurations of industrial air-conditioning device is complicated, the compressor of use is bigger than normal, and this has brought inconvenience to the pressure balance of refrigeration system Rapid Establishment and system oil return.Yet compressor start carries out when refrigeration system pressure balance, if system exists pressure differential, compressor start will have damage, and pressure differential is excessive also can cause compressor stuck or damage.For fear of compressor, in having the system of pressure differential, start at present, generally adopt time-delay method to solve, namely when compressor shutdown, circuit board is controlled compressor power-off 3-10 minute, relies on system pressure natural equilibrium.Compressor power-off time length in time expander method, is to determine according to the complexity of system, and this just makes the circuit board interchangeability of same brand industrial air-conditioning device poor, if unified compressor power-off time is just made troubles to user.Rely in addition system pressure difference natural equilibrium, easily make system oil be deposited in condenser, the heat-exchange capacity of condenser is declined.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of air-conditioning system with decompression function.
The technical solution adopted for the present invention to solve the technical problems is:
The air-conditioning system with decompression function, comprise compressor, condenser, expansion valve, evaporimeter, gas-liquid separator, a pressure release branch road is set between condenser inlet pipe and evaporator pipe, series electrical magnet valve in described pressure release branch road, opening and the pass of pass and compressor and open staggered synchronizeing of described magnetic valve, described magnetic valve place is also provided with a pressure sensor.
The pad of the inlet tube of described pressure release branch road and condenser is 200mm-500mm apart from the distance of the exhaust outlet of compressor.
The invention has the beneficial effects as follows: the present invention by arranging pressure release branch road between condenser inlet pipe and evaporator pipe, can rapidly the high-pressure refrigerant in condenser be leaked in the low pressure refrigerant of evaporimeter, the pressure balance of Rapid Establishment refrigeration system, while avoiding compressor again to start there is pressure differential in system, simultaneously because the latus rectum of pressure release branch road is larger, guaranteed the fine oil return of refrigeration system, improved the heat transfer effect of system, and magnetic valve place is also provided with a pressure sensor, this pressure sensor can feed back to pressure release information the control system of air-conditioning, facilitate control system to adjust the state of air conditioner.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 1 is the structural representation of a specific embodiment of the present invention, as shown in the figure, a kind of air-conditioning system with decompression function, by compressor 5, condenser 6, expansion valve 1, evaporimeter 3 and gas-liquid separator 4, form refrigerant-cycle systems, between the inlet tube of condenser 6 and the inlet tube of evaporimeter 3, a pressure release branch road 2 is set, pressure release branch road is comprised of copper tube and the magnetic valve 7 that is welded on copper tube middle part, and the Kai Heguan of magnetic valve 7 is subject to circuit board to control with the pass of compressor 5 and open to interlock to synchronize.
The inlet tube pad of pressure release branch road 2 and condenser 6 is 200mm-500mm apart from the distance of the exhaust outlet of compressor 5, and the gas that can effectively avoid compressor to discharge produces noise in pipeline.
Operation principle:
When air-conditioner refrigeration work: magnetic valve 7 cuts out, the 2 not conductings of pressure release branch road, the high temperature and high pressure gas that compressor 5 is discharged is cooling through condenser 6, by expansion valve 1 step-down, high temperature and high pressure gas becomes low-pressure gas and enters evaporimeter 3, then passes through the cooling of evaporimeter 3, become low-temp low-pressure gas and enter gas-liquid separator 4, through gas-liquid separator 4, fully gasify, low-temp low-pressure gas enters 5 compressors, the routine work that this kind of refrigeration cycle is air-conditioner.
When compressor quits work: circuit board is controlled magnetic valve 7 and opened, 2 conductings of pressure release branch road, now the high temperature and high pressure gas in condenser no longer flows to resistant expansion valve 1, but by pressure release branch road 2, flows into rapidly in evaporimeter 3 system pressure transient equilibrium; Because of the pass of magnetic valve 7 with open with compressor and synchronize; when compressor shutdown; system oil in condenser 6 is back in evaporimeter 3 by pressure release branch road 2; and magnetic valve 7 places are also provided with a pressure sensor 8; this pressure sensor 8 can feed back to pressure release information the control system of air-conditioning, facilitates control system to adjust the state of air conditioner.
If it is because of power-off that compressor quits work, when power-off time is less than three minutes and during power connection, circuit board is provided with the preferential function starting of magnetic valve 7, can set up the pressure balance of air-conditioner refrigerating system in 10 seconds.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
