Description
Technical field
The utility model relates to a kind of transporting equipment, especially a kind of CO2 refrigerating plant for refrigerator car.
Background technology
Cold-producing medium claims again refrigeration working medium, and it is in refrigeration system, constantly circulate and pass through the state variation of itself with the operation material of realization refrigeration.On market, existing mounted refrigerating container mainly uses CFCs and HCFCs as cold-producing medium, along with science and technology and the development of commercial production levels, earth environment worsens increasingly, the especially destruction of ozone layer and the impact of global warming, and the mankind's existence in serious threat.Scientific research discovery, destruction and the global warming of the discharge of the compound of refrigeration working medium CFCs and HCFCs to atmospheric ozone layer has direct relation, and the refrigeration of changing cold-producing medium and solution refrigerator car is urgent problem.This is the existing weak point of prior art.
Summary of the invention
The purpose of this utility model, be exactly for the existing deficiency of prior art, and provide a kind of technical scheme of the CO2 refrigerating plant for refrigerator car, the cooling device of this scheme adopts CO2 as refrigeration working medium, can not damage the ozone layer, and can effectively freeze, ensure the normal operation of refrigerator car.
This programme is achieved by the following technical measures: a kind of CO2 refrigerating plant for refrigerator car, comprise compressor, the feature of this programme is: the outlet of compressor is communicated with a refrigerant gas cooler, described refrigerant gas cooler is communicated with a reservoir by the first high pressure electric gate, on pipeline between refrigerant gas cooler and the first high pressure electric gate, be provided with temperature sensor and the first pressure sensor, the gas vent of reservoir is communicated with the entrance of compressor by the second high pressure electric gate, the liquid outlet of reservoir is communicated with an evaporimeter by high-pressure electronic expansion valve, evaporimeter is communicated with the entrance of compressor, on reservoir, be provided with the second pressure sensor.
Described temperature sensor is connected with a PLC controller, and described PLC controller is also connected with the first high pressure electric gate, the second high pressure electric gate, the first pressure sensor, the second pressure sensor, compressor, refrigerant gas cooler and evaporimeter respectively.
Described the first pressure sensor and the second pressure sensor all adopt ASK2050 pressure sensor.
Described temperature sensor adopts ASK11 temperature sensor.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this scheme, after the R744 gas (CO2) of low-temp low-pressure is sucked by compressor, pressurization becomes the R744 gas (CO2) of HTHP, R744 gas (CO2) heat release in refrigerant gas cooler of HTHP becomes the R744 gas (CO2) of middle temperature high pressure, heat is taken away by circulated air, the R744 gas (CO2) of middle temperature high pressure becomes the gas liquid mixture of medium temperature and medium pressure again after the expansion first of the first high pressure electric gate, the gas liquid mixture of medium temperature and medium pressure carries out gas-liquid separation in reservoir, gas part is sucked by compressor after by the second high pressure electric gate reducing pressure by regulating flow, liquid part becomes the gas of low-temp low-pressure after by the compound expansion of high-pressure electronic expansion valve in evaporimeter after heat absorption evaporation, air is through the heat exchanger surface cooling that is cooled in container, reach the object that the temperature inside the box is declined, the refrigerant gas of low-temp low-pressure is sucked by compressor again, so circulation, in when work, temperature sensor and the first pressure sensor can measure in the temperature and pressure of R744 gas (CO2) of warm high pressure, and corresponding pressure is sent to PLC controller, PLC controller can be adjusted the first high pressure electric gate and adjust, on reservoir, be provided with the second pressure sensor, can measure timely the pressure in reservoir, be convenient to PLC controller and adjust the first high pressure electric gate and the second high pressure electric gate, realize the adjustment to reservoir internal pressure.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
