The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The present embodiment provides a cabinet air conditioner, as shown in fig. 1 and fig. 2, the cabinet air conditioner includes a compressor 1, a condenser 2 and a first evaporation module 3, an exhaust port of the compressor 1 is connected to an inlet of the condenser 2, an outlet of the condenser 2 is connected to an inlet of the first evaporation module 3, and an outlet of the first evaporation module 3 is connected to an air suction port of the compressor 1; the cabinet air conditioner also comprises a second evaporation module 4, and the second evaporation module 4 is connected with the first evaporation module 3 in parallel.
Specifically, when the cabinet air conditioner is required to cool different heat of different equipment, a low-temperature and low-pressure refrigerant enters the compressor 1, is compressed into high-temperature and high-pressure superheated steam by the compressor 1, then is pressed into the condenser 2 for constant-pressure cooling, releases heat to a cooling medium, is cooled into a liquid refrigerant, is shunted to enter the first evaporation module 3 and the second evaporation module 4, absorbs heat in air-conditioning circulating water (air) in the first evaporation module 3 and the second evaporation module 4, cools the air-conditioning circulating water to achieve the purpose of refrigeration, flows out of the low-pressure refrigerant and is sucked into the compressor 1, and the refrigeration is realized by circulating operation; in this process, the first evaporation module 3 and the second evaporation module 4 may generate the same refrigeration capacity, or may generate different refrigeration capacities, and specifically, the corresponding refrigeration capacities may be controlled by controlling the amounts of the liquid refrigerants entering the first evaporation module 3 and the second evaporation module 4.
Of course, the present embodiment can also generate a cold amount, and only the first evaporation module 3 or the second evaporation module 4 needs to be turned off.
Because the cabinet air conditioner of the embodiment is provided with the first evaporation module 3 and the second evaporation module 4 at the same time, the heat generated by different equipment can be cooled by different cold quantities; of course, different cooling capacities can be used for cooling different heat generated by the same equipment; in addition, the two evaporation modules (the first evaporation module 3 and the second evaporation module 4) in this embodiment correspond to the same compressor 1 and the same condenser 2, and compared with the conventional method of installing two air conditioners with the same or different cooling capacities on a cabinet, this embodiment can save the cost of one compressor and one condenser, and occupies a small space in the cabinet.
In a specific embodiment:
the cabinet air conditioner further includes a receiver tank 5, and the receiver tank 5 receives the refrigerant flowing out of the condenser 2 and supplies the refrigerant to the first evaporation module 3 and/or the second evaporation module 4.
Specifically, the liquid storage tank 5 is mainly used for buffering the refrigerant, and the liquid storage tank 5 is an inlet-outlet type, and because the electronic expansion valves in the two evaporation modules are difficult to couple, when the opening degree of the electronic expansion valve of one flow path is reduced (the flow rate of the flow path is reduced), the refrigerant can excessively flow into the other flow path, and a large influence is caused on the other flow path, so that the liquid storage tank 5 is added to the outlet of the condenser 2, and the refrigerant flows out of the condenser 2, then flows through the liquid storage tank 5, is buffered in the liquid storage tank 5, and then flows into the first evaporation module 3 and/or the second evaporation module 4 respectively.
In a specific embodiment: the first evaporation module 3 and the second evaporation module 4 both comprise an electronic expansion valve 31 and an evaporator 32, one end of the electronic expansion valve 31 is connected with the condenser 2, the other end of the electronic expansion valve is connected with the evaporator 32, and the evaporator 32 is connected with the compressor 1.
For better explanation, it is assumed that the first evaporation module 3 includes a first electronic expansion valve and a first evaporator, and the second evaporation module 4 includes a second electronic expansion valve and a second evaporator;
in specific implementation, there are two cases:
firstly, when two different cold quantities are needed, the refrigerant flows out of a condenser 2 and is stored in a liquid storage tank 5, then the refrigerant is divided into two paths, the two paths of refrigerant respectively enter a first electronic expansion valve and a second electronic expansion valve and then enter a first evaporator and a second evaporator, and the heat in the air-conditioning circulating water (air) is absorbed in the first evaporator and the second evaporator, so that the air-conditioning circulating water is cooled to achieve the purpose of refrigeration, the flowing low-pressure refrigerant is sucked into a compressor 1, and the refrigeration is realized by the circulating operation; in the process, the two cold capacities can be adjusted to be matched with corresponding loads by controlling the amounts of the refrigerants flowing into the first evaporator and the second evaporator;
secondly, when only one type of cold is needed, in this case, the first evaporation module 3 and the second evaporation module 4 can both work, but the cold generated by the two modules is the same by controlling the flow rate of the refrigerant; the first evaporation module 3 or the second evaporation module 4 can also be closed, and only one path of evaporator is left for working.
In a specific embodiment:
the first evaporation module 3 and the second evaporation module 4 both comprise a first temperature collector 33, and the first temperature collector 33 is arranged on the evaporator 32 and used for monitoring the evaporation temperature; specifically, in the sense of refrigeration itself, refrigeration is the cold effect of the refrigerant liquid boiling and absorbing heat at a certain pressure in the evaporator. This pressure is the evaporation pressure, at which the corresponding temperature of the saturated gas of the refrigerant is called the evaporation temperature, the first temperature collector 33 is used to monitor the evaporation temperature on the corresponding evaporator; because the first evaporation module 3 and the second evaporation module 4 have mutually influenced and insufficient precision temperatures when working simultaneously, each evaporator corresponds to a standard evaporation temperature from the control point of view; when the cold energy of the load changes, the opening degree of the corresponding electronic expansion valve 31 is adjusted, the temperature collected by the first temperature collector 33 is compared with the standard evaporation temperature, and if the difference between the two is within a reasonable error range, the corresponding evaporation module is in a normal working state.
The first evaporation module 3 and the second evaporation module 4 both comprise a second temperature collector 34 and a third temperature collector 35, and the second temperature collector 34 and the third temperature collector 35 are respectively arranged at the inlet and the outlet of the evaporator 32 and are used for monitoring the superheat degree of the evaporator 32; specifically, the temperature difference acquired by the second temperature acquisition device 34 and the third temperature acquisition device 35 is the superheat degree of the corresponding evaporator, the superheat degree is the difference between the superheat temperature and the saturation temperature of the refrigerant in the same evaporation pressure of the refrigeration cycle, and is similar to the evaporation temperature, each evaporator corresponds to a standard superheat degree, when the cold energy of the load changes, the opening degree of the corresponding electronic expansion valve 31 is adjusted, the temperature difference acquired by the second temperature acquisition device 34 and the third temperature acquisition device 35 is compared with the standard superheat degree, and if the difference between the two is within a reasonable error range, the corresponding evaporation module is in a normal working state.
Specifically, the first temperature collector 33, the second temperature collector 34 and the third temperature collector 35 respectively include a thermal bulb. The temperature sensing bulb is also called a thermostatic controller, is a core component forming a thermostatic control valve, and plays an important role in realizing thermostatic control.
In a specific embodiment: the first evaporation module 3 and the second evaporation module 4 both comprise controllers, and when the loads corresponding to the first evaporation module 3 and the second evaporation module 4 change, the controllers adjust the opening degrees of the corresponding electronic expansion valves 31; the controller is further configured to: according to the relationship between the temperatures monitored by the first temperature collector 33, the second temperature collector 34 and the third temperature collector 35 and the preset temperature, whether the load corresponding to the first evaporation module 3 and the second evaporation module 4 is matched with the opening degree of the electronic expansion valve 31 corresponding to the load is judged.
In a specific embodiment: the cabinet air conditioner also comprises a gas-liquid separator 6, and the gas-liquid separator 6 is arranged at the air suction port of the compressor 1.
