Hot device 25, is worked by cold-storage device instead of high-temperature level compressor refrigeration system.
As shown in Figure 5 and Figure 6, example, the heating heat exchanger is located at the porch in air channel.The cooling heat exchanger position
In the porch in air channel.
As shown in figure 5, in the porch in ice chest air channel, setting heat exchanger.After experimental products enter ice chest by hot tank,
The cold-storage working substance of the cold-storage device through having cooled down, under the driving of pump enter heat exchanger, and the temperature regulating device 6 prior to ice chest steaming
Hair device carries out heat exchange with the air in case, and the heat that absorption brings from hot tank mitigates the cooling load of temperature controlling instruments, reaches contracting
The purpose of short recovery time.When the temperature of cold-storage working substance is identical with the air themperature in ice chest, stop the working medium of cold-storage device
Pump, is freezed by the evaporator of ice chest completely.
Such as Fig. 6, in the porch in hot tank air channel, heat exchanger is set.If the setting temperature of hot tank is higher than regenerative apparatus work
During the temperature of matter, when experimental products are in ice chest, regenerative apparatus working medium pump startup, by the heated work of the exhaust end of compressor
Matter, into the heat exchanger 2 in hot tank, is continued to heat by the heater of hot tank.After experimental products enter hot tank by ice chest, store
The accumulation of heat working medium of thermal, enters heat exchanger under the driving of pump, and heater prior to hot tank carries out heat with the air in case
Exchange, the cold that absorption brings from ice chest reaches the purpose for shortening recovery time.When the temperature and hot tank of the working medium of regenerative apparatus
When interior air themperature is identical, stop accumulation of heat working medium pump 14, heated by the heater of hot tank completely.

Storage in matter container 37.When storage heater is heated, after accumulation of heat container valve 39 and corresponding humidification heat exchanger loop valve 40 or
Heating circuit valve 17 is opened, and carries out heating work.
The present embodiment is conceived to the refrigerating efficiency for improving compressor, by introducing regenerator, need not be complete in temperature controlling instruments
During power refrigeration, compressor refrigeration system or total power are freezed, on the premise of ensureing that temperature controlling instruments freezes, unnecessary refrigeration
Ability is used for giving regenerator refrigeration.So when regenerator reaches design temperature, temperature controlling instruments can also be stablized in design temperature,
Now simply need the very low power refrigeration of refrigeration system.At this moment can by closing the compressor of whole mechanical refrigeration system,
Only freezed to temperature controlling instruments by regenerator system；Or close Partial shrinkage machine, such as high-temperature level compressor, by regenerator system
Instead of the method that high-temperature level compressor to freeze to the condenser of low-temperature level refrigeration system, the purpose of energy-conservation is reached.
The equipment that the regenerator can be used for temperature and humidity control degree.Humidity keep with dry the stage, it is necessary to refrigerating capacity,
Now, using the heat exchanger in temperature controlling instruments, the purpose of control humidity can also be realized according to method above.
Some temperature controlling instruments need to be changed back and forth between high temperature and low temperature, although or keep low temperature, finally to rise
Shut down after to normal temperature.The delivery temperature of mechanical refrigeration compressor is higher, it is necessary to cooling water takes away heat can condense.Introduce
Storage heater absorbs the partial heat of compressor air-discharging and stores, with the heat of this section store when temperature controlling instruments needs to heat up
Amount heating.It is typically all, using electrically heated method, electricity to be not only saved first with storage heater heating that temperature controlling instruments is raised to high temperature
Can, decrease the refrigerant pressure of cooling tower.
According to one of embodiment, the present embodiment discloses a kind of temprature control method, including：
Cold-storage device obtains the cryogenic energy that the compressor refrigeration system of lowest temperature is discharged, and is reached to cold-storage device default
Temperature, wherein compressor refrigeration system be capacity operation；
The temperature of temperature regulating device is detected, if the temperature of temperature regulating device reaches threshold value, cold-storage device passes through cooling heat exchanger
Cryogenic energy is discharged to temperature regulating device；
Stop the operation of high-temperature level compressor assembly, freezed to low-temperature level compressor assembly by cold-storage device, make low-temperature level
Refrigerant is condensed；Or/and
Regenerative apparatus obtains the high temperature energy of compressor air-discharging end release；
Temperature in detection regenerative apparatus, if the temperature in regenerative apparatus reaches compressor air-discharging end temperature or compressor row
Gas end temperature stops obtaining high temperature energy less than the temperature in regenerative apparatus, then regenerative apparatus；
The temperature of temperature regulating device is detected, if the temperature of temperature regulating device reaches threshold value, cold-storage device passes through heating heat exchanger
High temperature energy is discharged to temperature regulating device.
Preset temperature is reached in temperature regulating device, when refrigeration system starts regulation refrigeration work consumption, i.e. main evaporator valve closing
When just give cold-storage device refrigeration, or temperature controlling instruments operation before be dedicated for cold-storage device refrigeration, compressor assembly is made as far as possible
Capacity operation.
According to one of example, methods described is further included：The humidity of temperature regulating device is detected, if temperature regulating device is wet
Degree reaches threshold value, then cold-storage device discharges cryogenic energy by cooling heat exchanger to temperature regulating device；Or/and
The humidity of temperature regulating device is detected, if the humidity of temperature regulating device reaches threshold value, cold-storage device is exchanged heat by humidification water
Device is preheated to humidification water.
According to one of example, if the temperature in temperature regulating device reaches threshold value, cold-storage device is changed by cooling
The step of hot device discharges cryogenic energy to temperature regulating device further includes：Stop the operation of all compressor assemblies, only by storing
Device for cooling freezes in temperature controlling instruments.
According to one of example, if the temperature in temperature regulating device reaches threshold value, cold-storage device is changed by cooling
The step of hot device discharges cryogenic energy to temperature regulating device further includes：Stop the operation of superposition type compressor, cold-storage device
To the condenser refrigeration of baby compressor system, freezed to temperature controlling instruments by the evaporator of baby compressor system.
According to one of example, methods described is applied to shermal shock test chamber, the heating heat exchanger or/and the drop
Warm heat exchanger is located at the porch in air channel.
The other descriptions of method may refer to the embodiment of said system in the present embodiment, repeat no more.
Above content is to combine the further description that specific preferred embodiment is made to the present embodiment, it is impossible to recognized
The specific implementation for determining the present embodiment is confined to these explanations.Come for the present embodiment person of an ordinary skill in the technical field
Say, on the premise of the present embodiment design is not departed from, some simple deduction or replace can also be made, should all be considered as belonging to this
The protection domain of embodiment.
