State and constant temperature kept in environmental test chamber 300, it is to avoid the energy emptying in the running of compressor 10, save energy resource consumption,
Reduce testing cost.The circulating fan 310 is arranged at the top of the environmental test chamber 300, is mainly used in forcing effective
Air in space forms distinguished and admirable in evaporator external heat exchange, and air themperature is reduced, and then to the effective of environmental test chamber 300
Space is cooled, or the air in the pressure useful space forms distinguished and admirable in heater strip surface heat exchanging, and air themperature rise is entered
And the useful space to environmental test chamber 300 heats up.
Present invention further propose that a kind of control method of environmental test chamber 300.
Reference picture 4, Fig. 4 is the flow chart of the embodiment of control method one of the environmental test chamber 300 of the present invention.
In this embodiment, the control method comprises the following steps：
S10：When detecting the start of environmental test chamber 300, the circulating fan 310 is controlled to open；
S20：When receiving Product checking instruction, control the refrigeration system by the first coolant loop to the environment
Chamber 300 is cooled；
S30：When temperature in the environmental test chamber 300 is down to the first preset temperature, the refrigeration system is controlled to lead to
Cross the second coolant loop and store latent heat to the ice storage unit；
S40：After preset time, control the refrigeration system out of service, control the heating operation to described
Environmental test chamber 300 is heated up；
S50：When temperature in the environmental test chamber 300 rises to the second preset temperature, the ice water circulation water is controlled
Pump operation, the latent heat that will be stored in the ice storage unit is exchanged to the environmental test chamber 300 by the frozen water heat exchanger.
In the present embodiment, the circulating fan 310 is opened when environmental test chamber 300 is started shooting, namely environmental test chamber
While establishing machine by cable on 300, circulating fan 310 also opens operation immediately.
With further reference to Fig. 1, the refrigeration system 100 of the controller control environmental test chamber 300 and heating operation,
Low temperature or hot environment are simulated in the useful space of environmental test chamber 300, the work(under low temperature or hot environment is carried out to product
Can test.When receiving Product checking instruction, control refrigeration system is by the first coolant loop to the environmental test chamber 300
Cooled, namely low temperature environment is simulated according to the control program pre-set, now, the first magnetic valve 60 is controlled by controller
On conduct, the second magnetic valve 80 power-off close, from compressor 10 discharge the condensed decrease temperature and pressure of device 30 of high-temperature gas refrigerant
The further reducing pressure by regulating flow of restricting element 50 is entered by the first magnetic valve 60 afterwards, eventually passed in evaporator 70 and the useful space
Hot-air carry out heat exchange, absorb hot-air carry heat of vaporization re-compress into height into gaseous coolant into compressor 10
The gaseous coolant of warm high pressure, into subsequent cycle, until the temperature in environmental test chamber 300 is down to the first preset temperature；Now,
Because environmental test chamber 300 needs to keep the first pre-set temperature constant, it is necessary to control compressor 10 with minimum load operation, simultaneously
Part refrigerant after control compressor 10 does work is not involved in heat exchange in the useful space of environmental test chamber 300, but by the portion
Refrigerant is divided to be exchanged heat by the second magnetic valve 80 into ice storage unit 90, the latent heat deposit that the part refrigerant is carried is described to be stored
Ice production apparatus 90, the part refrigerant carries out heat exchange in ice storage unit 90 with the water in ice storage unit 90, absorbs the heat in water,
The reduction of its temperature is set to congeal into ice, the part refrigerant is stored in the ice of ice storage unit 90 by heat is carried in the form of the latent heat of condensation
In water.
, it is necessary to the test of switch test product after environmental test chamber 300 maintains the first pre-set temperature constant preset time
Environment, now needs the low temperature environment in the useful space of environmental test chamber 300 switching to hot environment, namely try environment
Tryoff 300 is heated up, at this time, it may be necessary to control refrigeration system out of service, heating startup optimization, namely control compressor
10 is out of service, controls heater heating power, and circulating fan 310 forces the air in the useful space to form distinguished and admirable in heater strip
Surface heat exchanging, air themperature rise, and then the useful space is heated up, until in the temperature in environmental test chamber 300
The second preset temperature is risen to, 25 DEG C are typically set in；Now, because environmental test chamber 300 needs to keep the second preset temperature permanent
It is fixed, but certain heat can be produced in test product during electrical testing, and also the partial heat is not enough to maintain compressor 10 again
With minimum load operation, the controller controls the first magnetic valve 60 and the second magnetic valve 80 to close, the ice water circulation water pump
91 operations, the latent heat that will be stored in the ice storage unit 90 is exchanged to the environmental test chamber by the frozen water heat exchanger 93
300, by the way that frozen water is passed through into frozen water heat exchanger 93 and the high temperature air progress heat exchange in environmental test chamber 300, realize to ring
Waste heat in border chamber 300 is cooled so that environmental test chamber 300 maintains the second pre-set temperature constant, the ice
Water circulation water pump 91 has frequency conversion function, and the frozen water flow of frozen water heat exchanger 93 is flowed into by VFC, environment is accurately controlled
Air themperature in the useful space of chamber 300.
The control method of the environmental test chamber 300 of the present invention, by the first coolant loop by the environmental test chamber 300
Temperature be down to after the first preset temperature, using the second coolant loop to the ice storage unit store latent heat, in environmental test chamber
Temperature in 300 is risen to after the second preset temperature, and the latent of the ice storage unit storage is discharged by the freezing water-flow circuit
Heat, make to keep the second pre-set temperature constant in the environmental test chamber 300, it is to avoid the energy during compressor operating is put
Sky, saves energy resource consumption, reduces testing cost.
Further, controlling what the refrigeration system was cooled by the first coolant loop to the environmental test chamber
When, the ice water circulation water pump operation is also controlled, the latent heat that will be stored in the ice storage unit is handed over by the frozen water heat exchanger
Shift to the environmental test chamber.
In the present embodiment, it is special in the environmental test chamber 300 alternately cyclic process of simulation low temperature environment and hot environment
It is not that high temperature during environmental test chamber 300 is from high temperature rapid drawdown to low temperature, namely more than 20 DEG C is down to less than 20 DEG C
Low temperature when, in order to reduce compressor 10 acting produce energy consumption, can also using the first coolant loop to environmental test chamber
While 300 cooling, ice water circulation water pump 91 is opened by the latent heat of condensation of the frozen water storage in ice storage unit 90, is changed by frozen water
Hot device 93 is discharged into environmental test chamber 300 so that environmental test chamber 300 now utilizes the first coolant loop and freezing simultaneously
Water-flow circuit carries out acceleration cooling, can further reduce the acting of compressor 10, saves energy consumption.
The preferred embodiments of the present invention are these are only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
