The air outlet of the air cooler 113 is also provided with a fan 114.
In the process of dehumidifying the humid air, the refrigerant in the evaporator 111 absorbs heat of the humid air, and then evaporates and flows into the compressor 101 communicating with the evaporator 111. The high-temperature, high-pressure gas refrigerant is compressed in the compressor 101 to a high-temperature, high-pressure gas refrigerant, which then flows into the tube side of the shell and tube heat exchanger 104, where it undergoes a first heat exchange cooling with condensed water flowing into a reservoir of the shell and tube heat exchanger 104, then flows into the water-cooled condenser 105, mixes with the low-temperature cooled gas from the air cooler 113, and flows into the water-cooled condenser 105, where the refrigerant is cooled by the externally introduced low-temperature cooled water to form a low-temperature, low-pressure liquid refrigerant, which then flows into the evaporator 111.

In the process of dehumidifying the humid air, the refrigerant in the evaporator 111 absorbs heat of the humid air, and then evaporates and flows into the compressor 101 communicating with the evaporator 111. The high-temperature and high-pressure gas refrigerant is compressed in the compressor 101 into a high-temperature and high-pressure gas refrigerant, and then flows into the tube side of the shell and tube heat exchanger 104, the high-temperature and high-pressure gas refrigerant performs first heat exchange cooling with condensate water in a water storage tank flowing into the shell and tube heat exchanger 104 in the tube side, then flows into the air cooler 113, the refrigerant flowing into the air cooler 113 is cooled by the dehumidified low-temperature air, then flows into the water cooled condenser 105, is mixed with the first heat exchange cooled high-temperature and high-pressure gas flowing into the water cooled condenser 105 through the shell and tube heat exchanger 104, flows into the water cooled condenser 105, and the refrigerant in the water cooled condenser 105 is cooled by low-temperature and low-pressure externally introduced low-temperature cooling water to form a low-temperature and.
In the two circulation loops, the shell and tube heat exchanger 104 is introduced, the outside of the shell and tube heat exchanger 104 is used for storing condensed water, and the condensed water can exchange heat with the refrigerant in the tube side arranged inside, so that the cold energy in the condensed water is recovered, and the problem of energy waste caused by directly discharging the condensed water in the prior art is avoided.
In order to control the flow of the refrigerant flowing into the air cooler 113 according to the temperature at the outlet of the air cooler 113, it is preferable that the energy-saving dehumidifier according to the embodiment of the present invention further includes a first three-way flow regulating valve 103-1, a second three-way flow regulating valve 103-2, and a first temperature sensor 115-1.
In one example, as shown in FIG. 1, a first three-way flow control valve 103-1 is located between compressor 101 and shell and tube heat exchanger 104, a second three-way flow control valve 103-2 is located between shell and tube heat exchanger 104 and water cooled condenser 105 or air cooler 113, and a first temperature sensor 115-1 is disposed at the outlet of air cooler 113.
In practical application, after the first three-way flow control valve 103-1 and the second three-way flow control valve 103-2 are added, the evaporator 111, the compressor 101, the first outlet of the first three-way flow control valve 103-1, the shell-and-tube heat exchanger 104, the first inlet of the second three-way flow control valve 103-2 and the water-cooled condenser 105 are sequentially connected and then still form a first circulation loop, and the evaporator 111, the compressor 101, the second outlet of the first three-way flow control valve 103-1, the air cooler 113, the second inlet of the second three-way flow control valve 103-2 and the water-cooled condenser 105 are sequentially connected and then form a third circulation loop.
Specifically, when the first temperature sensor 115-1 is disposed at the air outlet of the air cooler 113, the outlet air temperature of the air outlet can be detected, and the controller is electrically coupled to the first temperature sensor 115-1, and can control the on/off state of the first three-way flow control valve 103-1 according to the temperature detected by the first temperature sensor 115-1, that is, the flow rate of the refrigerant flowing through the air cooler 113 is controlled by controlling the on/off state of the first three-way flow control valve 103-1.
As shown in fig. 1, the refrigerant in the evaporator 111 absorbs heat of the humid air, and then evaporates and flows into the compressor 101 communicating with the evaporator 111. The gas refrigerant compressed into high temperature and high pressure in the compressor 101 flows into the first three-way flow regulating valve 103-1 after passing through the stop valve located behind the compressor 101, and since the controller can control the flow rate of the refrigerant entering the air cooler 113 according to the outlet air temperature of the air cooler 113 determined by the first temperature sensor 115-1, the first three-way flow regulating valve 103-1 completes the flow rate regulation of the first three-way flow regulating valve 103-1 at this time according to the instruction of the controller. A part of the high-temperature and high-pressure gas refrigerant flowing into the first three-way flow control valve 103-1 flows into the tube pass in the shell and tube heat exchanger 104 through the first outlet of the first three-way flow control valve 103-1, and the high-temperature and high-pressure gas refrigerant performs first heat exchange cooling with condensate water flowing into the water storage tank in the shell and tube heat exchanger 104 in the tube pass, and then flows into the water-cooled condenser 105 through the first inlet of the second three-way flow control valve 103-2, and is mixed with gas which is cryogenically cooled in the air cooler 113 through the second inlet of the second three-way flow control valve 103-2, and then flows into the water-cooled condenser 105, and the refrigerant in the water-cooled condenser 105 is cooled by the cryogenically cooled water introduced from the outside to form a low-temperature and low-pressure liquid refrigerant.
When a part of the high-temperature and high-pressure gas refrigerant flowing into the first three-way flow rate adjustment valve 103-1 passes through the second outlet of the first three-way flow rate adjustment valve 103-1 and flows into the air cooler 113, the high-temperature and high-pressure gas refrigerant flowing into the air cooler 113 is cooled by the dehumidified low-temperature air, then flows into the water cooled condenser 105 through the second inlet of the second three-way flow rate adjustment valve 103-2, is mixed with the first heat exchange cooling high-temperature and high-pressure gas flowing into the water cooled condenser 105 through the shell and tube heat exchanger 104 and flows into the water cooled condenser 105, and the refrigerant in the water cooled condenser 105 is cooled by the low-temperature and low-pressure externally-introduced low-temperature cooling water to form a low-temperature and low-.
It should be noted that, since the first three-way flow rate adjustment valve 103-1 is introduced into the circulation circuit, when the refrigerant is divided into two by the first three-way flow rate adjustment valve 103-1, the circulation process of the refrigerant passing through the first outlet of the first three-way flow rate adjustment valve 103-1, that is, the first circulation circuit provided in the embodiment of the present invention, and the circulation process of the refrigerant passing through the second outlet of the first three-way flow rate adjustment valve 103-1, that is, the third circulation circuit provided in the embodiment of the present invention.
For another example, as shown in fig. 2, a first three-way flow control valve 103-1 and a second three-way flow control valve 103-2 are sequentially located between the shell and tube heat exchanger 104 and the water-cooled condenser 105 or the air cooler 113, and a first temperature sensor 115-1 is disposed at an air outlet of the air cooler 113.
In practical application, after the first three-way flow control valve 103-1 and the second three-way flow control valve 103-2 are added, the evaporator 111, the compressor 101, the shell and tube heat exchanger 104, the second outlet of the first three-way flow control valve 103-1, the air cooler 113, the second inlet of the second three-way flow control valve 103-2 and the water-cooled condenser 105 are connected in sequence and then still form a second circulation loop, and the evaporator 111, the compressor 101, the shell and tube heat exchanger 104, the first outlet of the first three-way flow control valve 103-1, the first inlet of the second three-way flow control valve 103-2 and the water-cooled condenser 105 are connected in sequence and form a fourth circulation loop.
Specifically, when the first temperature sensor 115-1 is disposed at the air outlet of the air cooler 113, the outlet air temperature of the air outlet can be detected, and the controller is electrically coupled to the first temperature sensor 115-1, and can control the on/off state of the first three-way flow control valve 103-1 according to the temperature detected by the first temperature sensor 115-1, that is, the flow rate of the refrigerant flowing through the air cooler 113 is controlled by controlling the on/off state of the first three-way flow control valve 103-1.
As shown in fig. 2, the refrigerant in the evaporator 111 absorbs heat of the humid air, and then evaporates and flows into the compressor 101 communicating with the evaporator 111. The high-temperature and high-pressure gas refrigerant compressed in the compressor 101 flows into the tube pass in the shell and tube heat exchanger 104 after passing through the stop valve positioned behind the compressor 101, and the high-temperature and high-pressure gas refrigerant performs first heat exchange cooling with condensed water in the water storage tank flowing into the shell and tube heat exchanger 104 in the tube pass, and flows into the first three-way flow regulating valve 103-1, and because the controller can control the flow of the refrigerant entering the air cooler 113 according to the outlet air temperature of the air cooler 113 determined by the first temperature sensor 115-1, the first three-way flow regulating valve 103-1 finishes the flow regulation of the first three-way flow regulating valve 103-1 at this moment according to the instruction of the controller. A part of the high-temperature and high-pressure gas refrigerant flowing into the first three-way flow rate adjustment valve 103-1 flows into the air cooler 113 through the second outlet of the first three-way flow rate adjustment valve 103-1, the high-temperature and high-pressure gas refrigerant flowing into the air cooler 113 is cooled by the dehumidified low-temperature air, flows into the water-cooled condenser 105 through the second inlet of the second three-way flow rate adjustment valve 103-2, is mixed with the first heat-exchange cooled high-temperature and high-pressure gas flowing into the water-cooled condenser 105 through the shell and tube heat exchanger 104, flows into the water-cooled condenser 105, and is cooled by the low-temperature low-pressure externally introduced low-temperature water in the water-cooled condenser 105 to form a low-temperature low-pressure liquid refrigerant.
When a part of the high-temperature and high-pressure gas refrigerant flowing into the first three-way flow rate adjustment valve 103-1 flows into the water-cooled condenser 105 through the first outlet of the first three-way flow rate adjustment valve 103-1 and the first inlet of the second three-way flow rate adjustment valve 103-2, and flows into the water-cooled condenser 105 after being mixed with the gas cooled from the air cooler 113, the refrigerant in the water-cooled condenser 105 is cooled by the low-temperature and low-pressure liquid refrigerant introduced from the outside to form a low-temperature and low-pressure liquid refrigerant, and flows into the evaporator 111.
It should be noted that, since the first three-way flow rate adjustment valve 103-1 is introduced into the circulation circuit, when the refrigerant is divided into two by the first three-way flow rate adjustment valve 103-1, the circulation process of the refrigerant passing through the first outlet of the first three-way flow rate adjustment valve 103-1, that is, the second circulation circuit provided in the embodiment of the present invention, and the circulation process of the refrigerant passing through the second outlet of the first three-way flow rate adjustment valve 103-1, that is, the fourth circulation circuit provided in the embodiment of the present invention.
Further, in order to ensure that a proper amount of condensed water is placed in the water storage tank in the shell-and-tube heat exchanger 104, the cooling water in the water storage tank is conveniently discharged.
