Adopt above structure, when environment temperature is higher, can close cooling tower and open refrigeration machine, by refrigeration machine, the water in water tank is lowered the temperature, make the water temperature in water tank remain on lower temperature value, thus improve cooling water in freeze dryer condenser with the heat exchange effect of high-temperature high-pressure refrigerant, and then reduce the high-pressure of compressor, guarantee that compressor continues normal work, finally make the freeze-drying process of freeze dryer can trouble-free operation.In addition, when environment temperature is lower, can close refrigeration machine, only by cooling tower, cooling water be lowered the temperature, when guaranteeing compressor normal operation, can also reach energy-conservation effect.
Described water tank is closed.Airtight water tank, when guaranteeing that cooling water does not run off, can also improve compressor cooling speed.
The water inlet end of the water side of described the second water inlet pipe and the first outlet pipe is positioned at the same side of water tank inside, and the water side of the second water inlet pipe is towards the water inlet end of the first outlet pipe.By such structure, can, so that the cooling water from cryocooled can enter in freeze dryer condenser by the first outlet pipe the very first time, improve the cooling effect of freeze dryer condenser.
The utility model adopts above technical scheme, can be according to environment temperature, select refrigeration machine or cooling tower to lower the temperature to the cooling water in water tank, make compressor can continue normal work, extend the service life of compressor, environment temperature is reduced to minimum to the high-pressure of compressor, guarantees that freeze dryer freeze-drying can carry out smoothly.The utility model is simple in structure, and equipment all can be purchased on market, low cost of manufacture.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is water tank internal structure schematic diagram.
The specific embodiment
As shown in Figure 1 or 2, the utility model comprises water tank 1, freeze dryer condenser 2, refrigeration machine 3, the first outlet pipe 4, the first water inlet pipe 5 and more than one cooling tower 6; The water inlet end of described the first outlet pipe 4 is communicated with water tank 1, and the water side of the first outlet pipe 4 is communicated with the water inlet of freeze dryer condenser 2; The water inlet end of described the first water inlet pipe 5 is communicated with the delivery port of freeze dryer condenser 2, and the water side that the water side of described the first water inlet pipe 5 is connected with more than one the first arm 7, the first arms 7 is communicated with water tank 1; The water inlet of described refrigeration machine 3 is communicated with water tank 1 by the second outlet pipe 8, and the delivery port of refrigeration machine 3 is communicated with water tank 1 by the second water inlet pipe 9; The water inlet of described cooling tower 6 is communicated with the water side of the first water inlet pipe 5 by the second arm 10, and the delivery port of cooling tower 6 is communicated with water tank 1 by the 3rd water inlet pipe 11; On described the first arm 7 and the second arm 10, be respectively equipped with valve 12; The water inlet end of the water inlet end of described the first outlet pipe 4 and the second outlet pipe 8 is respectively equipped with water pump 13.
Described water tank 1 is closed.Airtight water tank 1, when guaranteeing that cooling water does not run off, can also improve compressor cooling speed.
As shown in Figure 2, the water inlet end of the water side of described the second water inlet pipe 9 and the first outlet pipe 4 is positioned at the same side of water tank 1 inside, and the water side of the second water inlet pipe 9 is towards the water inlet end of the first outlet pipe 4.By such structure, can, so that can enter freeze dryer condenser 2 by the first outlet pipe 4 very first time from the cooled cooling water of refrigeration machine 3, improve the cooling effect of freeze dryer condenser 2.
Operation principle of the present utility model: when environment temperature is when higher (if environment temperature is higher than 30 ℃), open the valve 12 on the first arm 7, and close the valve 12 on the second arm 10, start water pump 13 and refrigeration machine 3 on the second outlet pipe 8, cooling water in water tank 1 is entered in refrigeration machine 3 and is lowered the temperature by the second outlet pipe 8, cooling water after cooling is got back in water tank 1 by the second water inlet pipe 9, when freeze dryer starts freeze-drying work, water pump 13 on the first outlet pipe 4 starts, cooling water in water tank 1 enters freeze dryer condenser 2 from the first outlet pipe 4, and carry out heat exchange with the cold-producing medium of HTHP, cooling water temperature after heat exchange raises, through the first water inlet pipe 5 and the first arm 7, directly get back in water tank 1, the cooling water of getting back in water tank 1 is lowered the temperature by refrigeration machine 3 again, with this, circulate.By the cooling water in 3 pairs of water tanks 1 of refrigeration machine, lower the temperature, can make the temperature that enters the cooling water in freeze dryer condenser 2 remain on 15 ℃ of left and right, can greatly improve the cooling effect of freeze dryer condenser 2, thereby reduce the high-pressure of compressor, guarantee that compressor continues normal work, finally make the freeze-drying process of freeze dryer can trouble-free operation.
When environment temperature is when lower (if environment temperature is lower than 20 ℃), due to the water temperature in water tank 1 and environment temperature very nearly the same, can not open refrigeration machine 3, and open the valve 12 on the second arm 10, close the valve 12 on the first arm 7, when freeze dryer starts freeze-drying work, water pump 13 on the first outlet pipe 4 starts, cooling water in water tank 1 enters freeze dryer condenser 2 from the first outlet pipe 4, and carry out heat exchange with the cold-producing medium of HTHP, cooling water temperature after heat exchange raises, through the first water inlet pipe 5 and the second arm 10, enter in cooling tower 6 and lower the temperature, cooling water after cooling comes back in water tank 1, with this, circulate.
Certainly, according to environment temperature, the utility model also can select the cooling water of simultaneously opening after refrigeration machine 3 and 6 pairs of heat exchanges of cooling tower to lower the temperature.
