Description
Technical field
The utility model relates to a kind of GDJS.
Background technology
High/low temperature Alternate hot and humid case has another name called " GDJS ", belong to humiture test box series together, it is the testing equipment of the field indispensabilities such as aviation, automobile, household electrical appliances, scientific research, for testing and determining that electrician, electronics and other products and material carry out the parameter after the temperature environment change of high temperature, low temperature, Alternate hot and humid degree or constant test and performance, within certain range of tolerable variance, people completely can the correct and approx external environmental condition that stands in the processes such as use, storage, transport of model engineering product.
Adiabatic process forms, and its process is as follows: cold-producing medium is through compressor adiabatic compression to higher pressure, and the merit consumed makes delivery temperature raise, and cold-producing medium isothermally carries out heat exchange with surrounding medium through condenser heat is passed to surrounding medium afterwards.Rear cold-producing medium is through the acting of shutoff valve adiabatic expansion, and at this moment refrigerant temperature reduces.Last cold-producing medium isothermally from the object heat absorption that temperature is higher, makes cooled object temperature reduce by evaporimeter.This circulation goes round and begins again thus reaches the object of cooling.The refrigeration system of this chamber adopts the French unit freon refrigeration system producing safe health totally-enclosed compressor and form of 1 cover.The design ap-plication energy adjustment technology of refrigeration system, can ensure that refrigeration unit is normally run, and effectively can regulate again to the energy consumption of refrigeration system and refrigerating capacity, makes refrigeration system remain on best running status.Adopt balance temperature adjustment (BTC), both when refrigeration system in continuous operation, control system goes the output quantity of control heater by the result of PID automatic computing output according to the temperature spot of setting, finally reach a kind of dynamic equilibrium.Current existing GDJS complex structure, inconvenient operation, result of use is general.
Utility model content
It is easy to operate that the technical problems to be solved in the utility model is to provide a kind of case, can rapid translating high/low temperature or hygrothermal environment, the GDJS that operation stability is high.
For solving the problem, the utility model adopts following technical scheme:
A kind of GDJS, comprise casing, hermatic door, Programmable Logic Controller and refrigeration machine, described hermatic door and Programmable Logic Controller are located at casing front end, described hermatic door is connected with body pivot, described refrigeration machine is located at bottom half, described refrigeration machine side is provided with heater, described Programmable Logic Controller is electrically connected with refrigeration machine and heater respectively, described Programmable Logic Controller is provided with touch screen, described casing top is provided with humidifier, blower fan is provided with below described hermatic door, described touch screen, humidifier and blower fan are connected with Programmable Logic Controller telecommunications respectively.
As preferably, described hermatic door is provided with visual window and handle, the situation of visual window convenient observation casing.
As preferably, described handle is fixedly connected with hermatic door, and holding structure is stablized.
As preferably, described blower fan is provided with screen pack, can filtered air.
As preferably, described bottom half is provided with castor, facilitates mobile box.
The beneficial effects of the utility model are: the refrigeration machine of setting and heater conveniently carry out high/low temperature conversion, humidifier can change the air humidity in casing fast, keep experiment effect good, blower fan can keep casing ventilation effect good after test completes, touch screen conveniently manipulates, and can realize accurate control.
