Description

Technical Field

[0001] This utility model relates to the field of energy recovery technology, specifically a device capable of simultaneously providing low-temperature cooling and high-temperature heating. Background Technology

[0002] In industries such as food processing, slaughtering, and chemicals, there is a need for refrigeration during production and storage, as well as a demand for hot water or steam heating. These two demands arise after energy output, serving only the refrigeration or heating system. However, after heat loss or internal heat exchange that increases the heat value, the heat is dissipated into the air through pipes without corresponding heat recovery, resulting in heat loss. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a device that can simultaneously perform low-temperature cooling and high-temperature heating, thus solving the problem of heat loss caused by the lack of corresponding heat recovery.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device capable of simultaneously performing low-temperature cooling and high-temperature heating, comprising:

[0005] The working fluid production and receiving end is the foundation for establishing the working fluid and the platform for receiving the energy output of the working fluid;

[0006] The working fluid conversion end is a channel that constructs the flow space of the working fluid at the working fluid production and receiving ends and generates working fluid energy output.

[0007] The working fluid conversion end includes a first conversion channel and a second conversion channel. The first conversion channel is independent of the second conversion channel. The first conversion channel and the second conversion channel are connected to generate a heat exchange channel through the main heat exchanger.

[0008] The first conversion channel includes a flow pipe connected to the main heat exchanger, and an output pipe for conveying the working fluid to the production and receiving end is installed on the output end of the main heat exchanger.

[0009] In one embodiment, the working fluid production and receiving end includes a refrigeration compressor connected to a first conversion channel and a heating compressor connected to a second conversion channel.

[0010] The flow pipe is connected to the output end of the refrigeration compressor, and the output pipe is connected to the input end of the refrigeration compressor. A liquid storage tank for receiving the condensate after heat exchange is connected along the extension trajectory of the output pipe. A dryer filter and an expansion valve connected to the liquid storage tank are installed on the output pipe along the direction of the working fluid flow.

[0011] In one embodiment, the output pipe is connected to a refrigeration evaporator for converting the liquid working fluid into a gaseous state along its gradual extension from the expansion valve to the output end of the refrigeration compressor.

[0012] In one embodiment, the second conversion channel includes a guide pipe installed at the output end of the heating compressor, the guide pipe is connected to a heating converter, a water inlet is installed on the heating converter, and a return pipe connected to the input end of the heating converter is connected to the output end of the main heat exchanger.

[0013] In one embodiment, two water inlet terminals are provided on the heat exchanger from top to bottom. The lower water inlet terminal is connected to a cold water pipe, and the upper water inlet terminal is connected to a water delivery pipe to carry away the heat inside the heat exchanger.

[0014] In one embodiment, the output pipe extends from the output end of the refrigeration evaporator to the output end of the refrigeration compressor.

[0015] Compared with the prior art, this utility model provides a device that can simultaneously perform low-temperature cooling and high-temperature heating, and has the following beneficial effects:

[0016] In the technical solution disclosed in this utility model, using the heat discharged during refrigeration as the heat source for heating not only reduces the condensation temperature during refrigeration but also increases the evaporation temperature during heating, greatly improving the refrigeration and heating efficiency while saving a lot of energy. In addition, based on the independence of the first conversion channel and the second conversion channel, the working fluids flowing between them do not flow, avoiding the generation of turbulent flow between hot and cold, thereby improving the heat exchange efficiency of the first conversion channel and the second conversion channel in carrying their respective working fluids in the main heat exchanger.

[0017] By installing two water inlet terminals on the heating converter, the first energy exchange occurs when the heating compressor outputs high-temperature working fluid, producing hot water or steam at temperatures as high as 80℃-140℃ to meet heating requirements. Furthermore, by generating further working fluid heat exchange in the main heat exchanger, some of the heat lost in the heating converter is compensated, thereby reducing the power consumption of the heating compressor.

[0018] In summary, after meeting the constant operating conditions of one side, this device can reduce the power input of another operating condition by utilizing the principle of heat and cold recovery, thereby achieving the goal of energy saving. Attached Figure Description

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Figures 1-3 This specific embodiment addresses the problem of the following: In food processing, slaughtering, and chemical industries, refrigeration is required during production and storage, while hot water or steam heating is also needed. These two demands, after energy output, serve only the refrigeration or heating system. However, after heat loss or internal heat exchange leading to an increase in heat value, the heat is dissipated into the air through pipes without corresponding heat recovery, resulting in heat loss. Based on the above-described problems, a technical concept is proposed that, while meeting existing refrigeration and heating requirements, recover subsequent cold and heat for exchange to reduce the energy consumption of subsequent production. This results in a device capable of simultaneous low-temperature refrigeration and high-temperature heating. Utilizing the heat discharged during refrigeration as a heat source for heating not only lowers the condensation temperature during refrigeration but also increases the evaporation temperature during heating, greatly improving refrigeration and heating efficiency while saving significant energy.

[0027] The device described in this embodiment, which can simultaneously perform low-temperature refrigeration and high-temperature heating, specifically includes a working fluid production and receiving end 1, which establishes the basis for producing the working fluid and a platform for receiving the energy output by the working fluid. Specifically, it includes a refrigeration compressor 11 and a heating compressor 12. The refrigeration compressor 11 generates energy to be output to the refrigeration system, while the heating compressor 12 generates energy to be output to the heating system.

[0028] To facilitate the exchange and recovery of cold and heat, a working fluid conversion end 2 is provided in this embodiment. This end 2 constructs a channel for the working fluid to flow through the working fluid production and recovery end 1 and generate working fluid energy. The working fluid conversion end 2 includes a first conversion channel 21 connected to the refrigeration compressor 11 and a second conversion channel 22 connected to the heating compressor 12. The first conversion channel 21 is independent of the second conversion channel 22. The first conversion channel 21 and the second conversion channel 22 work together to generate a heat exchange channel through the main heat exchanger 3. The first conversion channel and the second conversion channel 22 are independent of each other, and the working fluid flowing between them does not flow, thus avoiding the generation of cold and hot turbulence and improving the heat exchange efficiency of the first conversion channel 21 and the second conversion channel 22 in carrying their respective working fluids in the main heat exchanger 3.

[0029] The first conversion channel 21 includes a flow pipe 211 connected to the main heat exchanger 3. An output pipe 212 for conveying the working fluid to the working fluid production and receiving end 1 is installed on the output end of the main heat exchanger 3. The output pipe 212 extends from the output end of the refrigeration evaporator 215 to the output end of the refrigeration compressor 11. The flow pipe 211 is connected to the output end of the refrigeration compressor 11, and the output pipe 212 is connected to the input end of the refrigeration compressor 11. A liquid storage tank 213 for receiving the condensate after heat exchange is connected along the extension trajectory of the output pipe 212. A dryer filter 214 communicating with the liquid storage tank 213 and an expansion valve are installed on the output pipe 212 along the working fluid flow direction. A refrigeration evaporator 215 for converting the liquid working fluid into a gaseous state is connected along the path from the expansion valve to the output end of the refrigeration compressor 11.

[0030] The second conversion channel 22 includes a guide pipe 221 installed at the output end of the heating compressor 12. The guide pipe 221 is connected to a heating converter 222. A water inlet 223 is installed on the heating converter 222. There are two water inlet 223s on the heating converter 222, arranged from top to bottom. The water inlet 223 at the lower end is connected to a cold water pipe, and the water inlet 223 at the upper end is connected to a water delivery pipe to carry away the heat from the heating converter 222. First, when the heating compressor 12 outputs high-temperature working fluid, a first energy exchange occurs, outputting hot water or steam at temperatures as high as 80℃-140℃ to meet the heating demand. In addition, further working fluid heat exchange occurs in the main heat exchanger 3, thereby compensating for some of the heat lost in the heating converter and reducing the power consumption of the heating compressor 12.

[0031] The output end of the guide pipe 221, which is a self-made heat exchanger 222, extends towards the main heat exchanger 3 and is connected to a liquid storage tank 213 and an expansion valve. The output end of the main heat exchanger 3 is connected to a return pipe 224 that connects to the input end of the heat exchanger 222. The working fluid introduced into the main heat exchanger 3 through the guide pipe 221 exchanges heat with the working fluid brought into the main heat exchanger 3 through the flow pipe 211, resulting in a temperature difference between the working fluid in the guide pipe 221 and the flow pipe.

[0032] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
