Description

Technical Field

[0001] The invention relates to the field of dehumidifiers, in particular to an energy-saving constant-temperature dehumidifier. Background Art

[0002] A constant temperature dehumidifier is a device used to adjust indoor temperature and humidity. It combines refrigeration and dehumidification functions to provide a comfortable environment indoors. The refrigeration system of a constant temperature dehumidifier is usually composed of a compressor, evaporator, condenser and expansion valve.

[0003] Dehumidification process of the dehumidifier: When the constant temperature dehumidifier is started, the compressor compresses the refrigerant into a high-temperature and high-pressure gas heat medium, which enters the condenser. The condenser acts as a heat exchanger to cool the gas heat medium into a high-pressure liquid refrigerant, while releasing heat to the outside. The high-pressure liquid refrigerant enters the evaporator through the expansion valve. The expansion valve reduces the pressure of the liquid refrigerant, causing it to evaporate and absorb heat from the air, causing the surface temperature of the evaporator to drop. When the air passes through the evaporator, the moisture in it condenses into a liquid state, which is then collected in a container inside the dehumidifier and discharged through a drain pipe. Constant temperature dehumidifiers are usually equipped with a temperature sensor to monitor the indoor temperature. When the indoor temperature is higher than the set comfort temperature, the dehumidifier will start the cooling mode to lower the indoor temperature. When the indoor temperature reaches the set temperature, the dehumidifier will stop cooling to maintain a constant temperature.

[0004] When the indoor temperature is lower than the set comfort temperature in the cold winter, the constant temperature dehumidifier will not increase the indoor temperature because its main function is to dehumidify and keep the temperature constant. However, some high-end constant temperature dehumidifiers have auxiliary heating function, which can start the heating element to increase the indoor temperature when the indoor temperature is detected to be too low. This requires the installation of an electric heater to increase the indoor temperature so that the constant temperature dehumidifier can maintain the temperature within the range of 26 degrees ± 1 degree; and the current 1kw compressor must be matched with a 2kw electric heater to control the temperature in winter within the range of 26 degrees ± 1 degree, which consumes a lot of energy and greatly increases the cost of use.

[0005] Therefore, in order to solve the deficiencies in the prior art, it is necessary to design an energy-saving constant temperature dehumidifier with a simple structure. Summary of the invention

[0006] The invention provides an energy-saving constant-temperature dehumidifier to solve the problems of the prior art.

[0007] The objective of the present invention can be achieved through the following technical scheme: An energy-saving constant temperature dehumidifier comprises: an evaporator, a compressor, a condenser, a water cooler, an A valve, a B valve, an expansion valve and a temperature sensor, the evaporator is connected to the compressor through a pipeline one, the compressor is connected to the water cooler through a pipeline two, the upper end of the pipeline two is connected to the upper end of the condenser through a pipeline three, the A valve is arranged on the pipeline three, the B valve is arranged on the pipeline two, the lower end of the condenser is connected to the water cooler through the pipeline four, the water cooler is connected to the evaporator through the pipeline five, the expansion valve is arranged on the pipeline five, and the water cooler is connected with a water pipe inlet and a water pipe outlet.

[0008] As a further improvement, the water pipe inlet is connected to the water outlet of a water pump, and the water inlet of the water pump is connected to a water tower.

[0009] As a further improvement, an induced draft fan is provided at the air outlet of the condenser.

[0010] As a further improvement, a second induced draft fan is provided at the air outlet of the evaporator.

[0011] Compared with the prior art, the energy-saving constant temperature dehumidifier of the present invention has the following beneficial effects:

[0012] The present invention utilizes the temperature detection of the temperature sensor to control the direction of the high-temperature and high-pressure gas heat medium in the compressor. When the indoor temperature is higher than the set temperature, the heat of the compressor is released externally through the water cooler to cool the indoor temperature. When the indoor temperature is lower than the set temperature, the heat of the compressor is released internally through the condenser to raise the indoor temperature. There is no need to use a conventional electric heater for heating, and the heat of the compressor is reasonably utilized to achieve energy saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is combined with the embodiments and attached Figure 1 , the technical solution of the present invention is further elaborated.

[0018] Example 1

[0019] An energy-saving constant temperature dehumidifier comprises: an evaporator 1, a compressor 2, a condenser 3, a water cooler 4, an A valve 5, a B valve 6, an expansion valve 7 and a temperature sensor 8, wherein the evaporator 1 is connected to the compressor 2 via a pipe 11, the compressor 2 is connected to the water cooler 4 via a pipe 2 12, the upper end of the pipe 2 12 is connected to the upper end of the condenser 3 via a pipe 3 13, the A valve 5 is arranged on the pipe 3 13, the B valve 6 is arranged on the pipe 2 12, the lower end of the condenser 3 is connected to the water cooler 4 via a pipe 4 14, the water cooler 4 is connected to the evaporator 1 via a pipe 5 15, the expansion valve 7 is arranged on the pipe 5 15, and the water cooler 4 is connected to a water pipe inlet 16 and a water pipe outlet 17.

[0020] As a further preferred embodiment, the water pipe inlet 16 is connected to the water outlet of the water pump 9 , and the water inlet of the water pump 9 is connected to the water tower 10 .

[0021] As a further preferred embodiment, an induced draft fan 18 is provided at the air outlet of the condenser 3, and the heated air is blown out by the induced draft fan 18.

[0022] As a further preferred embodiment, an induced draft fan 19 is provided at the air outlet of the evaporator 1, and the dehumidified air is blown out by the induced draft fan 19.

[0023] like Figure 1As shown, the use process of the present invention is as follows: Refrigeration and dehumidification working principle (non-cold winter): The temperature sensor 8 sets the temperature within the range of 26 degrees ± 1 degree. When the temperature is higher than 27 degrees, the A valve 5 is instructed to close, the B valve 6 is opened, and the water pump 9 is operated to pump the water in the water tower 10 into the water cooler 4. The compressor 2 discharges the high-temperature and high-pressure gas heat medium, enters the water cooler 4, releases the heat of the gas heat medium, and turns into a low-temperature and high-pressure gas heat medium. Then, it is intercepted by the expansion valve 7 and turns into a low-temperature and low-pressure liquid refrigerant. It absorbs heat through the evaporator 1 and turns into a low-temperature and low-pressure gas heat medium and returns to the compressor 2. In this process, the wet air is cooled and lowered through the evaporator 1, and the water therein condenses and is collected and discharged from the machine. The humid air is dried by the evaporator 1 and sent back to the room to achieve dehumidification, ensuring that the indoor temperature is reduced to the set temperature range to achieve constant temperature.

[0024] Working principle of heating and dehumidification (in cold winter): The temperature sensor 8 sets the temperature within the range of 26 degrees ± 1 degree. When the temperature is lower than 25 degrees, the A valve 5 is instructed to open and the B valve 6 is closed; the water pump 9 stops, the water cooler 4 stops the water inlet and outlet, and the compressor 2 discharges the high-temperature and high-pressure gas heat medium, enters the condenser 3 and becomes a low-temperature and high-pressure gas heat medium, and then passes through the expansion valve 7 to intercept and become a low-temperature and low-pressure liquid refrigerant. It absorbs heat through the evaporator 1 and becomes a low-temperature and low-pressure gas heat medium and returns to the compressor 2. In this process, the wet air is cooled by the evaporator 1, and the water in it condenses and is collected and discharged from the machine. At this time, the air temperature is about 12 to 15 degrees. At the same time, the heat is released in the process of becoming a low-temperature and high-pressure gas heat medium through the condenser 33 to heat the air, heating it to about 26 degrees, and the heated air is sent back to the room to ensure that the indoor temperature rises to the set temperature range to achieve constant temperature.

[0025] The present invention utilizes the temperature detection of the temperature sensor to control the direction of the high-temperature and high-pressure gas heat medium in the compressor. When the indoor temperature is higher than the set temperature, the heat of the compressor is released externally through the water cooler to cool the indoor temperature. When the indoor temperature is lower than the set temperature, the heat of the compressor is released internally through the condenser to raise the indoor temperature. There is no need to use a conventional electric heater for heating, and the heat of the compressor is reasonably utilized to achieve energy saving.

It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
