DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0032] Plate heat exchanger is a commonly used heat exchange equipment, mainly used to achieve heat transfer between different fluids. It consists of a series of parallel metal plates. The fluid flows between the plates and transfers heat through the surface of the plates. Plate heat exchangers have the advantages of high heat transfer efficiency, small footprint, and easy maintenance. They are widely used in chemical, food, pharmaceutical, energy and other fields. The working principle of the plate heat exchanger is to achieve high heat transfer efficiency through the characteristics of large heat transfer surface area and strong heat transfer capacity. When the fluid flows between the plates, heat is transferred through the surface of the plates to achieve heat exchange between cold and hot fluids. At the same time, the design structure of the plate heat exchanger allows the fluid to flow through the plates multiple times, increasing the efficiency of heat transfer.

[0033] A solution dehumidifier is a device used to remove moisture from the air. It uses a desiccant in a solution to absorb moisture from the air, thereby reducing the humidity of the air. Typically, a solution dehumidifier includes a container containing a desiccant solution and a ventilation system. When air flows through the desiccant solution through the ventilation system, moisture is absorbed, thereby reducing the humidity in the air. Solution dehumidifiers are commonly used in industrial production, laboratories and other places, which can effectively control the humidity of the air, help protect equipment and materials, and improve production efficiency.

[0034] A regenerator is a device used to recover and reuse waste heat from an air conditioner. Through the regenerator, the air conditioning system can convert waste heat into energy, thereby improving the energy efficiency and energy-saving performance of the system. Regenerators usually use heat exchangers or heat pump technology to achieve waste heat recovery and reuse, effectively reducing energy waste, lowering operating costs, and reducing carbon emissions.

[0035] The compressor is a key component in the air conditioner. It is responsible for compressing low-pressure, low-temperature gas into high-pressure, high-temperature gas, so that the heat in the air is absorbed and discharged to the outside, thereby achieving the cooling effect of the air conditioner. The compressor is usually driven by an electric motor and plays a vital role in the air conditioner.

[0036] A four-way valve is a valve used to control the flow direction of a fluid. It usually has four interfaces and can connect four pipes. A four-way valve can achieve fluid control in different directions, such as diverting the fluid from one pipe to two pipes, or merging the fluids in two pipes into one pipe. Four-way valves are widely used in hydraulic systems, air compression systems and other fields to control the flow direction and pressure of fluids.

[0037] Evaporation pipe is a piping system used to transfer heat and materials in the evaporation process. It is usually made of materials with good thermal conductivity, such as stainless steel, copper, aluminum, etc. The function of the evaporation pipe is to convert liquid materials into gaseous state and transport them to where they are needed for further processing or utilization.

[0038] A blower is a device used to generate airflow or wind, and is usually used in industrial production processes such as ventilation, gas transportation, and drying. The blower inhales and outputs air or gas through rotating impellers or propellers, thereby generating a certain airflow pressure and flow. There are many types and working principles of blowers, including centrifugal blowers, axial flow blowers, fence blowers, etc., which are widely used in industry, construction, environmental protection and other fields.

[0039] As introduced in the background technology, at present, air conditioners often use evaporators for cooling and dehumidification. In order to meet the dehumidification requirements, the air temperature needs to be reduced to a very low level. In order to meet the air supply temperature requirements, reheating needs to be increased, resulting in increased energy consumption. In addition, the dehumidification operation of air conditioners is mostly intermittent dehumidification, which cannot achieve a comfortable feeling of constant temperature and humidity. In order to solve the problem that the existing refrigeration cycle device has high energy consumption and uses intermittent dehumidification, resulting in low solution evaporation efficiency, the embodiments of the present application provide a refrigeration cycle device and an air conditioner.

[0040] The present application provides a refrigeration cycle device, such as Figure 1 As shown ( Figure 1 The controller is not shown), the refrigeration cycle device includes:

[0041] A compressor 100, a four-way valve 200, a regenerator 300, a condensing device 400, a liquid storage device 500, a heat exchanger device 600, an evaporating device 700 and a controller. The compressor is connected to the regenerator and the heat exchanger device respectively by the four-way valve. The heat exchanger device is connected to the outlet of the liquid storage device, the inlet of the liquid storage device is connected to the regenerator, and the controller communicates with the heat exchanger device.

[0042] The high-temperature and high-pressure refrigerant discharged from the compressor enters the regenerator through the four-way valve. The solution in the regenerator absorbs the heat from the exhaust pipe, and the temperature of the solution increases. The refrigerant after heat exchange flows through the condensing device and enters the evaporating device. The evaporating device cools the fresh air and blows out cold air into the room.

[0043] The vaporized refrigerant passes through the plate heat exchanger (i.e., the heat exchanger in the heat exchanger equipment) and exchanges heat with the solution, then flows through the four-way valve back to the compressor, completing a closed-loop cycle;

[0044] The controller is used to control the heat exchanger device so that the refrigerant exchanges heat with the solution, or to control the heat exchanger device so that the evaporation device exchanges heat with the solution, according to the real-time pressure and saturation pressure of the refrigerant inlet of the heat exchanger device, so that the real-time pressure of the refrigerant outlet of the heat exchanger device is less than the saturation pressure of the refrigerant outlet of the heat exchanger device.

[0045] In the above-mentioned refrigeration cycle device, a heat exchanger and an evaporating device are arranged, so that the controller controls the heat exchanger device so that the refrigerant exchanges heat with the solution, or controls the heat exchanger device so that the evaporating device exchanges heat with the solution, according to the real-time pressure and saturation pressure of the refrigerant inlet of the heat exchanger device, so that the real-time pressure of the refrigerant outlet of the heat exchanger device is less than the saturation pressure of the refrigerant outlet of the heat exchanger device, so that the present application utilizes the heat absorption of the refrigerant evaporation to cool the solution, thereby achieving the effect of fully utilizing energy, thereby solving the problem that the existing refrigeration cycle device has high energy consumption and uses intermittent dehumidification, resulting in low solution evaporation efficiency.

[0046] In one embodiment of the present application, Figure 2 As shown, the controller is used to control the heat exchanger device so that the refrigerant exchanges heat with the solution, or to control the heat exchanger device so that the evaporation device exchanges heat with the solution, according to the real-time pressure and saturation pressure of the refrigerant inlet of the heat exchanger device, including:

[0047] When the real-time pressure P1 of the refrigerant inlet of the heat exchanger is less than the saturated pressure P2 of the refrigerant inlet of the heat exchanger, the first valve 610 is opened and the second valve 620 is closed, so that the refrigerant exchanges heat with the solution;

[0048] When the real-time pressure P1 of the refrigerant inlet of the heat exchanger is greater than or equal to the saturated pressure P2 of the refrigerant inlet of the heat exchanger, and the temperature T1 of the refrigerant inlet of the heat exchanger is greater than or equal to the temperature T2 of the outlet of the liquid storage device, the first valve is closed and the second valve is opened, so that the evaporation device performs heat exchange on the solution. If the real-time pressure P3 of the refrigerant outlet of the heat exchanger device is less than the saturated pressure P4 of the refrigerant outlet of the heat exchanger device at this time, the operation is terminated. If the real-time pressure P3 of the refrigerant outlet of the heat exchanger device is greater than or equal to the saturated pressure P4 of the refrigerant outlet of the heat exchanger device at this time, the heating power of the liquid storage device is increased, for example, the second heating wire is turned on.

[0049] When the real-time pressure P1 of the refrigerant inlet of the heat exchanger is greater than or equal to the saturated pressure P2 of the refrigerant inlet of the heat exchanger, and the temperature T1 of the refrigerant inlet of the heat exchanger is less than the temperature T2 of the outlet of the liquid storage device, the heating power of the liquid storage device is increased, for example, the second heating wire is turned on, until the temperature T1 of the refrigerant inlet of the heat exchanger is greater than or equal to the temperature T2 of the outlet of the liquid storage device.

[0050] Specifically, the solution is cooled by utilizing the heat absorption of the refrigerant evaporation, and a multi-stage heating and cooling method is adopted to fully utilize the heat and cold in the recovery system to ensure complete evaporation of the refrigerant.

[0051] In one embodiment of the present application, Figure 3 As shown, the heat exchanger device 600 includes: a first valve 610, a second valve 620 and a heat exchanger 630, the first end of the first valve is connected to the solution inlet of the heat exchanger, the solution outlet of the heat exchanger is connected to the second end of the second valve, the refrigerant inlet of the heat exchanger is connected to the four-way valve, the refrigerant inlet of the heat exchanger is connected to the evaporation device, the second end of the second valve is also connected to the regenerator, the second end of the first valve and the first end of the second valve are respectively connected to the outlet of the liquid storage device, and the first valve and the second valve are respectively electrically connected to the controller.

[0052] Specifically, Figure 3As shown, a first pressure sensor 640, a first saturated pressure sensor 650 and a first temperature sensor 660 are arranged at the outlet of the first evaporation exhaust pipe 710; a second pressure sensor 670 and a second saturated pressure sensor 680 are arranged at the refrigerant outlet of the plate heat exchanger; a second temperature sensor 900 is arranged between the discharge port of the liquid storage device 500 and the plate heat exchanger. When the second valve is closed and the first valve is opened, the solution and the refrigerant exchange heat in the plate heat exchanger. When the second valve is opened and the first valve is closed, the solution directly enters the solution dehumidification generator without passing through the plate heat exchanger.

[0053] In one embodiment of the present application, Figure 3 As shown, the evaporation device 700 includes: a first evaporation exhaust pipe 710, a solution dehumidification generator 720, a first blower 730 and a second blower 740, the outlet of the solution dehumidification generator is connected to the first blower, the inlet of the solution dehumidification generator is connected to the second blower, the air outlet of the first blower is connected to the first evaporation exhaust pipe, and the solution at the outlet of the liquid storage device flows through the solution dehumidification generator to cool and dehumidify the fresh air sucked in by the second blower.

[0054] In one embodiment of the present application, Figure 3 As shown, the evaporation device 700 also includes: a water pump 750 and a second evaporation drain pipe 760, the second evaporation drain pipe is used to connect the refrigerant inlet of the heat exchanger device and the condensing device, the circulation pipeline of the water pump passes through the solution dehumidification generator and the second evaporation drain pipe, and the second evaporation drain pipe is used to use the water pumped into the water pump as a cooling medium for solution dehumidification.

[0055] First, after the refrigerant passes through the condenser and the expansion valve, the refrigerant enters the branch, one end is connected to the third valve, and one end is connected to the refrigerant coil flowing in the first evaporation pipe. At the same time, the fresh air after dehumidification flows in the first evaporation pipe, thereby cooling the fresh air after dehumidification. The third valve is used to adjust the flow rate of the refrigerant flowing through the two branches. One end of the refrigerant flow side in the second evaporation pipe is connected to the third valve, and the other end of the second evaporation pipe is connected to the refrigerant coil flowing in the first evaporation pipe. At the same time, cooling circulating water is introduced into the second evaporation pipe through the circulation of the water pump, and the cooling circulating water circulates through the solution dehumidification generator at the same time, serving as the cooling medium during solution dehumidification, so that the dehumidification process is approximately isothermal.

[0056] Among them, the refrigerant in the first evaporation pipe and the fresh air after dehumidification do not contact heat exchange, the cooling circulating water in the second evaporation pipe and the refrigerant do not contact heat exchange, the fresh air and the solution in the solution dehumidification generator are mixed for dehumidification, and the fresh air-solution mixture in the solution dehumidification generator and the cooling circulating water do not contact heat exchange.

[0057] In one embodiment of the present application, the solution dehumidification generator is a multi-stage cooling dehumidification structure. Both the regenerator and the solution dehumidification generator adopt a multi-stage heating and cooling method, which not only ensures sufficient contact area for heat exchange but also enables a high concentration difference between the solution inlet and outlet.

[0058] In one embodiment of the present application, Figure 3 As shown, the refrigeration cycle device further includes a third valve 800, and the third valve is used to connect the second evaporation exhaust pipe and the condensing device.

[0059] Specifically, after passing through the condenser and the expansion valve, the refrigerant enters a branch path. One path flows through the first evaporation exhaust pipe to cool the fresh air, and the other path flows through the second evaporation exhaust pipe to cool the incoming water. A third valve is provided to adjust the flow rate of the refrigerant flowing through the two branches. The cooling water enters the solution dehumidification generator through the action of a water pump and serves as a cooling medium during solution dehumidification, so that the dehumidification process is carried out approximately isothermally, thereby reducing the decrease in its moisture absorption capacity due to the temperature rise of the solution.

[0060] In one embodiment of the present application, Figure 3 As shown, the condensing device includes a condenser 410 and an expansion valve 420 which are connected in sequence, the inlet of the condenser is connected to the regenerator, and the outlet of the expansion valve is connected to the second evaporation exhaust pipe.

[0061] In one embodiment of the present application, the liquid storage device is a multi-stage heating structure. The regenerator and the solution dehumidification generator both use multi-stage heating and cooling methods, which not only ensures sufficient contact area for heat exchange but also enables a high concentration difference between the solution inlet and outlet.

[0062] like Figure 3 As shown, a liquid discharge port 511 is provided at the bottom of the solution storage tank 510 of the liquid storage device 500, and a liquid return port 512 is provided in the middle. After the solution is discharged from the liquid discharge port, it is cooled by heat exchange with the refrigerant through the plate heat exchanger and then passes through the solution dehumidification generator. The solution dehumidification generator is connected to the fresh air inlet. After the solution has completed dehumidification of the fresh air, it enters the regenerator through the liquid return pipeline to absorb the heat of the refrigerant exhaust pipe, and enters the liquid storage device through the liquid return port under the action of the water pump;

[0063] like Figure 3As shown, the liquid storage device 500 also includes a solar panel 520, an inverter 530, a first heating wire 540, a second heating wire 550 (the first heating wire is normally open, and the second heating wire is normally closed), a spraying device 560, a water pump 570 for spraying, and a power regulator 580, wherein the first heating wire remains normally open, and the second heating wire is provided with a power regulator (the power regulated by the heating wire is increased according to the number of adjustments), and the regenerated solution enters the liquid storage spraying device through the liquid return port, and the solution spraying increases the contact area with the air, thereby promoting the evaporation of water in the solution. In addition, the spraying solution is heated by the first heating wire to accelerate the evaporation of water.

[0064] The present application also provides an air conditioner, the air conditioner comprising: a refrigeration cycle device that performs any one of the above. By setting a heat exchanger and an evaporation device, the controller controls the heat exchanger device to make the refrigerant exchange heat with the solution, or controls the heat exchanger device to make the evaporation device exchange heat with the solution, according to the real-time pressure and saturation pressure of the refrigerant inlet of the heat exchanger device, so that the real-time pressure of the refrigerant outlet of the heat exchanger device is less than the saturation pressure of the refrigerant outlet of the heat exchanger device, so that the present application utilizes the refrigerant evaporation heat absorption to cool the solution, so as to achieve the effect of fully utilizing energy, thereby solving the problem that the existing refrigeration cycle device has high energy consumption and uses intermittent dehumidification to cause low solution evaporation efficiency.

[0065] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.
