Regulation and control about temperature
(1) refrigeration
The climatic chamber refrigeration unit adopts air-cooled single-stage double-compressor refrigeration unit, and compressor is 2 of totally-enclosed flexible swirl type cold compressors.
Because the inner thermic load of liquid petroleum product storage condition (climatic chamber) is unfixed.Compressor is along with four seasons variation day and night, and refrigerating capacity also is different.If select a compressor for use,, can cause indoor temperature low excessively when indoor thermic load hour; When indoor thermic load is big, may cause indoor temperature too high.Therefore, this programme is designed to double-compressor, opens quantity according to condition of different through the adjustment compressor and regulates refrigerating capacity.
Double-compressor parallel is installed.This system adopts two compressors to be parallel in the whole refrigeration system.System can control the platform number that compressor is opened according to the needs of climatic chamber.Than common single compressor system, double compressor system is distributed to refrigerating capacity on two compressors, can regulate the refrigerating capacity to climatic chamber effectively.
Refrigeration unit core component compressor is totally-enclosed flexible swirl type cold compressor.Its major advantage shows: stable, vibration is little, noise is low; Simple in structure, parts are few, light weight, reliability are high.
(2) heating
Because common ptc material is influenced by ambient humidity after the heating, damage easily, and a little less than the corrosion resistance, be not suitable for using in the case.So, adopt the heating of stainless steel electrothermal tube in this programme, long service life, affected by environment little, corrosion resistance is strong.
And the heating system modular combination in this programme adds heat through stepless power regulating device free adjustment, can freely export according to heat control needs.In addition, because the heating system modular combination, i.e. each heater interface standard, modularization is handled, and institute is so that change.
The stepless power regulating device is realized adding the adjusting of heat through the adjustment to stainless steel electrothermal tube heating power.Its principle is that through indoor temperature probe detection indoor temperature, if indoor temperature is lower than setting value, unlatching heating so according to the difference of detected temperatures and design temperature, determines the adjusting ratio of stainless steel electrothermal tube heating power.The size of current that the electrodeless power regulating device passes through through SCR control realizes the control to stainless steel electrothermal tube overall power.
(3) evaporimeter
Air-cooled single-stage double-compressor refrigeration unit in this programme adopts the staggered form evaporator designs, improves radiating efficiency, cuts down the consumption of energy.Staggered form evaporimeter to the double compressor system design can effectively utilize the evaporimeter area of dissipation.The evaporator pipeline interconnection of two cover compressors is arranged, under the situation of only opening a compressor, also can effectively utilize the area of dissipation of all evaporators.
(4) aeration device
Aeration device can be selected according to the requirement of climatic chamber indoor temperature and humidity and gas concentration.Can select heat-exchanger rig for use in the new blower fan.Heat-exchanger rig mainly is the exchange that realizes indoor exhaust wind and outdoor novel wind energy in the new blower fan, to reclaim the energy that indoor exhaust wind is taken away, reaches maximum energy-conservation purpose.Heat-exchanger rig in the new blower fan in this programme, energy-saving effect can reach more than 70% (containing), effectively energy savings and reduction operating cost.In addition, aeration device can also dispose different air cleaners as requested, with the effect that realizes purifying the air of a room.
(5) air circulation device
Air circulation device comprises circulating fan, plays the effect of circulation room air, is effectively to guarantee the uniform visual plant of indoor temperature and humidity.This equipment is owing to contacting with room air, so can select anticorrosion explosion-proof fan.
(6) concentrate air conditioning cabinet
Climatic chamber has certain fluctuation requirement to indoor humiture, and this requires air blow and return in certain control range with regard to having determined to indoor aircondition.
In this programme, can be placed on what all air processors were concentrated in the concentrated air conditioning cabinet.Wherein air processor can comprise new air heat-exchange, refrigeration, heating and damping device.After the air of concentrating air conditioning cabinet to return circulation is concentrated the state point that cooling, humidification, heat treated require to climatic chamber, concentrated delivering in the climatic chamber.
Concentrate the setting of air conditioning cabinet, can solve effectively:
1) Space Facilities is arranged difficulty;
2) the aerial temperature and humidity fluctuation range exceeds requirement.Common air-conditioning carries out piecemeal to air to be handled, and does not reach the state point of requirement of experiment, and the fluctuation of humiture value is serious;
3) the air blow and return temperature difference is big;
4) the climatic chamber wind speed is too high;
Problem such as 5) noise is big.
In the practical application, air conditioning cabinet can be selected the accessory with anticorrosion explosion prevention function for use, adopts stainless steel, 20g pipe or brass tube evaporimeter (salt mist experiment is indoor).Whole box body can adopt anticorrosion, explosion-proof stainless steel to make.
