The high temperature air conditioner has the advantages of simple structure, easy implement, and good high temperature resistance, and can work normally in the air environment with high temperature of 78 DEG C.
Description
Technical field
The utility model relates to a kind of air-conditioner technical field, is specifically related to a kind of high-temperature air regulator of regulating temperature and humidity.
Background technology
The air-conditioner refrigerating system that is used for hot environment at present adopts warm refrigerant R134a usually, when environment temperature is higher than 70 ℃, have that pressure at expulsion and temperature are too high, condensation not exclusively or the too little shortcoming of degree of supercooling, refrigeration system cisco unity malfunction or efficient are low excessively, and safety and reliability are difficult to ensure; Adopt R142b that volume refrigerating capacity compressor too little (be about R134a 30%), system bulk is excessive, cost is high defective are arranged again; In the above-mentioned two kinds of systems of worst hot case suction, excessive discharge temperature, shortcoming that reliability is low are arranged all.
The utility model content
The utility model is at the deficiencies in the prior art, designed and developed out a kind of simple in structurely, implements easily, and resistance to elevated temperatures is good, can temperature up to 78 ℃ air ambient in the air conditioner of normal operation.
The utility model is achieved through the following technical solutions:
A kind of high-temperature air regulator, include a compressor, the output of compressor is communicated with the input of condenser, the output of condenser is communicated with the input of evaporimeter by expansion valve, the output of evaporimeter is communicated with a gas-liquid separator, the output of described condenser divides two-way to be communicated with subcooler, wherein one the tunnel directly is connected with the shell side inlet of subcooler, the outlet of subcooler shell side is connected with described evaporimeter by described expansion valve, another road is passed through in order to the throttling step-down, the throttling control valve of regulating flow is connected with the tube side inlet of subcooler, and the tube side outlet of subcooler is by the pipeline connection between pipeline and evaporimeter and the gas-liquid separator.
A kind of high-temperature air regulator, described subcooler are provided with in order to control the Sensitive Apparatus of described throttling control valve aperture size.
A kind of high-temperature air regulator, described Sensitive Apparatus are sensor.
The high-temperature air conditioner device adopts refrigerant R134a, though volume refrigerating capacity compressor is higher, when environment temperature was higher than 70 ℃, condensation was incomplete or degree of supercooling is too little, so that system's cisco unity malfunction or job insecurity; And the refrigeration system that adopts R142b has volume refrigerating capacity compressor too little (be about R134a refrigeration system 30%), volume is excessive, cost is high defective.For this reason, set up a cold loop excessively of being made up of throttling control valve and subcooler in refrigeration system, the preceding cold-producing medium degree of supercooling of expansion valve is increased, the raising system is in job stability, operating efficiency and the reliability of worst hot case; Utilized the boil-off gas that flows out in the cold loop to reduce the suction temperature of compressor, so that reduce the delivery temperature of compressor, the raising system is in the safety and the reliability of worst hot case.
The beneficial effects of the utility model are embodied in:
1) adopts high-temperature air conditioner refrigeration system of the present utility model, can improve its operating temperature range, improve stability, reliability and the efficient work of system works.
2) the utility model reduces the air-conditioning system volume, improves volumetric efficiency, energy efficiency, reduces cost of goods manufactured.
3) effectively reduce the suction temperature of high-temperature air conditioner compressor, cause the delivery temperature appropriateness of compressor to reduce, improve the reliability of system works.
Description of drawings
Shown in accompanying drawing.
The utility model is formed by connecting through pipeline and valve by refrigeration compressor (1), condenser (2), throttling control valve (3), subcooler (4), expansion valve (5), evaporimeter (6), gas-liquid separator (7) and air cleaner.The output of compressor (1) is communicated with the input of condenser (2), the output of condenser (2) divides two-way to be communicated with subcooler (4), wherein one the tunnel directly is connected with the shell side inlet of subcooler (4), the outlet of subcooler (4) shell side is connected with evaporimeter (6) by expansion valve (5), another road is passed through in order to the throttling step-down, the throttling control valve (3) of regulating flow is connected with the tube side inlet of subcooler (4), and the tube side outlet of subcooler (4) is by the pipeline connection between pipeline and evaporimeter (6) and the gas-liquid separator (7).
The utility model operation principle and process are as described below: 1. cold-producing medium absorbs the heat of the air that is cooled in evaporimeter (6), is evaporated to gaseous state by liquid state; 2. compressor (1) is discharged high temperature and high pressure gas with the compression of low-temperature low-pressure refrigerant gas; 3. high-temperature high-pressure refrigerant to the high temperature heat source heat release, cools off, is condensed into highly pressurised liquid in condenser (2).At worst hot case, often condensation degree of supercooling incomplete or condensate liquid is too little; 4. partial condensation liquid enters subcooler (4) evaporation heat absorption through throttling control valve (3) shunting, step-down, and the temperature of main flow condensate liquid is further reduced; 5. supercooled liquid obtains the low pressure liquid (containing flash steam) of corresponding evaporating temperature by expansion valve (5) throttling step-down, enters evaporimeter (6) heat absorption and flashes to cryogenic gas, mixes with the low-temperature steam that flows out in the subcooler, and 1. the process that turns back to finishes cyclic process.
