As shown in fig. 1 and 2, the high-power constant temperature dehumidifier includes a casing 1, and a compressor 2, a condenser 3, a capillary tube 4, an evaporator 5 and a liquid storage tank 6 all located in the casing 1. The compressor 2, the condenser 3, the capillary tube 4, the evaporator 5 and the liquid storage tank 6 are sequentially connected, and the liquid storage tank 6 is connected with the compressor 2 to form a working medium circulation loop. A water-cooled heat exchanger 8 is arranged between the compressor 2 and the condenser 3. The working medium, called "working substance" for short, is a medium substance by which various heat engines or thermal equipment can convert heat energy and mechanical energy into each other. In this embodiment, the working fluid is a refrigerant.
The casing 1 is provided with an air inlet 1a and an air outlet 1b, and the air blower 7 is installed at the air outlet 1b. Condenser 3 sets up with evaporimeter 5 side by side, and condenser 3 is close to air outlet 1b, and evaporimeter 5 is close to air intake 1a for the air current gets into casing 1 back from air intake 1a, discharges from air outlet 1b behind evaporimeter 5 and the condenser 3 in proper order.
In this embodiment, the air inlet 1a is located at the top of the casing 1, and the opposite two sides of the casing 1 are both provided with air outlets 1b. The condenser 3 and the evaporator 5 are provided with two groups, the air inlet 1a is positioned between the two evaporators 5, and the two condensers 3 respectively correspond to the air outlets 1b on the two sides of the machine shell 1. Therefore, when the dehumidifier works, air flow enters the shell 1 from the air inlet 1a and is discharged from the air outlet 1b after passing through the two groups of condensers 3 and the evaporators 5 respectively, so that the dehumidifier has larger air inlet amount, can dehumidify large air flow, improves the dehumidification efficiency, and meets the application requirements of vegetable greenhouses and flower greenhouses.
Two air outlets 1b are arranged at two opposite sides of the machine shell 1, and the edge of each air outlet 1b is provided with an annular flange 1c, so that the air outlets have a longer air supply distance. The annular rib 1c is covered with a protective screen 14 for protecting the blower 7.
A dryer 9 is connected between the condenser 3 and the capillary tube 4. The drier 9 can remove moisture in the working medium, and when the working medium is instantly gasified through the capillary tube, the moisture in the working medium is prevented from freezing and blocking the capillary tube. The bottom end of the evaporator 5 is provided with a water collecting mechanism 10. The water collecting mechanism 10 can collect the condensed water dropping from the surface of the evaporator 5.
As shown in fig. 3, the edge of the bottom of the housing 1 is movably provided with a mounting plate 1e through a hinge 1d, and the mounting plate 1e is provided with wheels 1f. When the dehumidifier moves, the mounting plate 1e is turned over to be in contact with the bottom surface of the machine shell 1, and the wheels 1f are positioned at the bottom of the machine shell 1. When the dehumidifier is installed, the installation plate 1e is turned over to the outside of the machine case 1, the wheels 1f are positioned at the side part of the machine case 1, and the bottom surface of the machine case 1 can be contacted with the installation surface. The hinge 1d, the mounting plate 1e and the case 1 are installed through screws, and after the dehumidifier is installed, the mounting plate 1e can be detached.
The high-power constant-temperature dehumidifier of the embodiment further comprises a control device 11, a high-pressure end pressure sensor 12, a low-pressure end pressure sensor 13 and a temperature sensor 14, wherein the high-pressure end pressure sensor 12 is located between the compressor 2 and the water-cooling heat exchanger 8, the low-pressure end pressure sensor 13 and the temperature sensor 14 are both located between the evaporator 5 and the liquid storage tank 6, and the compressor 2, the blower 7, the high-pressure end pressure sensor 12, the low-pressure end pressure sensor 13 and the temperature sensor 14 are all connected with the control device 11. The temperature sensor 14 and the two pressure sensors can send temperature or pressure signals of corresponding positions to the control device 11, and when the control device 11 judges that the temperature or pressure signals are abnormal, an alarm is given or the compressor 2 and the blower 7 are controlled to stop.
The control device 11 is positioned at one end of the casing 1, and the capillary tube 4, the water-cooling heat exchanger 8, the dryer 9 and the water collecting mechanism 10 are positioned at the other end of the casing 1, so that the dehumidifier is compact in structure.
When the high-power constant-temperature dehumidifier of the embodiment works, the working medium is compressed into liquid by the compressor 2, the temperature of the working medium is higher at the moment, and the working medium enters the condenser 3 after being initially cooled by the water-cooled heat exchanger. The condenser 3 heats the dry cool air after passing through the evaporator 5. Then the working medium enters the evaporator 5 through the capillary 4 after passing through the dryer 9, at the moment, the working medium is converted from a liquid state to a gas state to absorb a large amount of heat, so that the temperature of the evaporator 5 is lower, and the evaporator 5 cools and dehumidifies the passing damp and hot air. Then the working medium enters the liquid storage tank 6 and then enters the compressor 2 to start the next cycle.
The compressor 2 compresses the working medium from gas state to liquid state, the temperature of the working medium rises, the temperature of the working medium is initially reduced by the water-cooling heat exchanger 8, so that the temperature of the dry and cold air passing through the condenser 3 is the same as or similar to the temperature of the original damp and hot air, and the temperature in the vegetable greenhouse or the flower greenhouse is not influenced by dehumidification. The water-cooled heat exchanger 8 takes tap water as a refrigerating machine, can be recycled, and effectively saves energy. The refrigeration efficiency of the water-cooling heat exchanger 8 can be controlled by controlling the water flow speed, and the control process is simple.
What has been described above are merely some of the embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
