(2), calculate the indoor volume of houselet, measure cubicle indoor temperature, calculated according to thermodynamical equilibrium equation by Indoor Air Body reduces the heat needed for 16 ~ 25 DEG C, by controlling switch priority and the time of modules or system, control refrigeration and interior Fresh air circulation;
(3), be first turned on the switch of VMC, after 5 ~ 15min, while refrigeration module, radiating module, conduction cooling module are opened Close, then turn the fresh air cycle rate of VMC down, after this state maintains 0.5 ~ 2.5h, close part refrigeration module to temperature Balance;Also may be selected to close:VMC is first closed, conduction cooling module and refrigeration module is turned off, finally closes radiating module.
Preferably, the refrigeration module, radiating module, conduction cooling module, VMC, refrigeration module are connected to control Device processed, the controller are connected with timer, timer control modules or the time for switching execution state of system and elder generation Afterwards, the semiconductor chilling plate packet in refrigeration module, which connects controller and controlled by controller, opens and closes.Modules and system Thin portion structure makes its control more convenient, careful, refrigeration and fresh air circulate operation simple and effective.
Preferably, the thermal insulation board is glass mat, plastic foamboard, polyurethane foam board, centrifugation stripping fiber One kind in cotton, aerogel blanket, evacuated panel, its thickness are 8-30mm.Above material and thickness, which are set, makes its heat-insulating property at this Almost few heat exchanges in the involved temperature difference of invention, ensure the heat and quality requirement of fresh air, it is ensured that fresh air efficiency.
Preferably, step(2)In, it is isobaric enthalpy change that the room gas of calculating, which reduces temperature institute calorific requirement parameter,.Fresh air Connected after unlatching with room, so isobaric enthalpy change is most rational parameter.
Further, the refrigeration module is to include the arrays of 10 ~ 40 semiconductor chilling plates, total refrigeration work(of refrigeration module Rate is not less than 0.4kW, no more than 3kW.Refrigeration module and refrigeration work consumption are applied to cubicle, then then influence security greatly.
Further, the volume of the cubicle is not more than 150m3.The volume of cubicle ensures refrigerating efficiency, such as continues to carry It is big, also dangerous that high refrigeration work consumption improves refrigerating capacity power consumption.
Further, step(2)In, heat calculates what can be changed by being considered as isometric drying air temperature in room Isobaric enthalpy change, is multiplied by coefficient(1.2~2.0)Obtain.This operation calculates for convenience, and 1.2 ~ 2.0 can be considered safety factor, experience Value.
Further, also there is temperature control module in the controller.Temperature control module facilitates temperature control and controller to adjust at any time.
The beneficial effects of the present invention are:A kind of refrigeration of cubicle of the present invention and the method for producing fresh air, technique letter It is single, easy to control.Refrigeration module and VMC work respectively, are operated by the keying of controlling switch, convenient and simple;And Refrigeration and the keying of fresh air respectively is controlled then to realize automation with the controller connection timer of temperature control module by one Control, and technique is flexible;Parameter is can obtain to set control only by the volume and temperature for calculating cubicle Concrete condition, and without manual and direct Automated condtrol, realize Intelligent refrigeration and fresh air air-supply.The design essence of the present invention Ingeniously, automation technolo and flexibly, is suitable for the quick of cubicle and balance refrigeration band fresh air, is the good choosing of ventilation of relieving summer heat summer Select.
Brief description of the drawings
Fig. 1 is the technique and control process schematic block diagram of the embodiment of the present invention.
Embodiment
In order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art, letter will be made to embodiment below Singly introduce.
