When work, the evaporator section that air-flow first passes through heat pipe tentatively cools down to air-flow and (can be cooled down 5 DEG C -10 DEG C), then led to
Pervaporation device cools down again to air-flow, can realize that lower leaving air temp is (comparable to be not provided with heat under identical refrigerating capacity
2 DEG C -5 DEG C are reduced before pipe), and the heat that the evaporator section of heat pipe absorbs can be added at condensation segment to the air-flow release flowed through
Heat, the aperture by controlling proportional-regulating air valve can make fraction flow through condensation segment, and the other parts of air-flow are from bypass air hose
It flows through, two parts air-flow mixes at the condensation segment rear of heat pipe, to can realize that the adjusting of leaving air temp (can be achieved 0 DEG C -6 DEG C
Adjustable range), temperature adjustment process is without increasing power consumption.
Further, the adjustable temp, refrigerating system further includes one and is connected in parallel on the second cold of 2 both ends of the first condenser
Condenser 9, second condenser are arranged in air duct 5 and are located at the rear that bypass air hose 5.1 exports, the entrance of the first condenser and
The entrance of second condenser is connect by ratio triple valve 10 with the outlet of compressor 1.Part can be made cold by ratio triple valve
Matchmaker flows into the second condenser, is heated to the air-flow flowed through by the second condenser, due to flowing into the refrigerant of the second condenser
Flow can be by ratio threeway valve regulation, therefore can further improve the adjustable range (can increase by 22 DEG C -25 DEG C) of leaving air temp.
In the present embodiment, second condenser 9 be air cooled condenser, the first condenser 2 be air cooled condenser or
Water cooled condenser；If the first condenser is air cooled condenser, condenser wind is additionally provided on the first condenser
Machine.First condenser is preferably water cooled condenser, and cooling efficiency is higher, is conducive to the refrigeration effect for improving refrigeration system.

To air-flow carry out heat release, can further regulating outlet air temperature, flow into the second condenser cold medium flux it is bigger, leaving air temp is got over
It is high.
In the control method, the adjustable range of temperature is divided into two grades (first grade and second gears)；When need to adjust
Temperature range then only carries out leaving air temp adjusting (i.e. not toward second by proportional-regulating air valve in first grade (such as 0 DEG C -6 DEG C)
Condenser conveys refrigerant, only controls the aperture of proportional-regulating air valve)；When need the temperature range that adjusts second gear (such as 6 DEG C-
25 DEG C) in, then keep the aperture of proportional-regulating air valve maximum, and (specially control by ratio triple valve regulating outlet air temperature
Into the flow of the second condenser conveying refrigerant).The control logic of the control method is simple, without coordinate proportional-regulating air valve and
Work relationship between ratio triple valve.
In temperature adjustment process, it is utilized respectively the first temperature sensor, second temperature sensor, third temperature sensor and surveys
Gas flow temperature and leaving air temp after measuring inlet air temperature, adjusting for the first time, and ratio is controlled with measurement data effect control parameter
Adjusting air valve and the work of ratio triple valve guarantee that leaving air temp perseverance is the temperature needed.
It, can according to the technique and scheme of the present invention and its hair it is understood that for those of ordinary skills
Bright design is subject to equivalent substitution or change, and all these changes or replacement all should belong to protection scope of the present invention.
