[0032] The following is combined Figures 1-5 This invention describes an integrated refrigeration and heating system.

[0033] The integrated cooling and heating system provided in this embodiment of the utility model includes a cooling cycle system 100, a heating cycle system 200, and a controller.

[0034] The refrigeration cycle system 100 includes a refrigeration unit 110 and a pumping unit 300. The inlet of the refrigeration unit 110 is connected to a water source 400 via a first pipe 120, and the outlet of the refrigeration unit 110 is connected to the inlet of the pumping unit 300 via a first loop 130. The outlet of the pumping unit 300 is connected to the end user. The refrigeration unit 110 can be an electric refrigeration unit or a ground source heat pump unit. In summer, the refrigeration cycle system 100 starts, and water (e.g., at 13°C) enters the refrigeration unit 110 through the first pipe 120 for heat exchange. After heat exchange, the water temperature decreases (e.g., to 6°C), and the heat-exchanged water enters the pumping unit 300 through the first loop 130. The pumping unit 300 then delivers the heat-exchanged water to the end user 500.

[0035] The heating circulation system 200 includes a heating unit 210 and a pumping unit 300. The heating unit 210 can be a boiler. The inlet of the heating unit 210 is connected to a water source 400 via a second pipe 220, and the outlet of the heating unit 210 is connected to the inlet of the pumping unit 300 via a second loop 230. The outlet of the pumping unit 300 is connected to the end user. In winter, the heating system starts, and water (e.g., 40°C) enters the heating unit 210 through the second pipe 220 for heating. After heating, the water temperature rises (e.g., 50°C), and the heated water enters the pumping unit 300 through the second loop 230. The pumping unit 300 then delivers the heated water to the end user 500.

[0036] The refrigeration unit 110, heating unit 210, and pumping unit 300 are all electrically connected to a controller, which controls the operation of at least one of the refrigeration unit 110 and heating unit 210. In cooling mode, the controller controls the operation of the cooling unit and pumping unit 300. At this time, the heating unit 210 is shut down, and the water source 400, refrigeration unit 110, pumping unit 300, and end user 500 are sequentially connected. Water enters the refrigeration unit 110 for heat exchange and is then pumped to the end user 500 via the pumping unit 300. In heating mode, the controller controls the operation of the heating unit 210 and pumping unit 300. At this time, the refrigeration unit 110 is shut down, and the water source 400, heating unit 210, pumping unit 300, and end user are sequentially connected. Water enters the heating unit 210 for heating and is then pumped to the end user 500 via the pumping unit 300. When the refrigeration unit 110 is a ground source heat pump unit, the ground source heat pump unit can perform heating. At this time, both the refrigeration unit 110 and the heating unit 210 are in operation. The water source 400, the refrigeration unit 110, the pumping unit 300 and the end user are connected in sequence. The water heated by the heating unit 210 and the water after heat exchange by the refrigeration unit 110 both enter the pumping unit 300 and are pumped to the end user 500 by the pumping unit 300.

[0037] The integrated cooling and heating system provided in this embodiment of the utility model has a shared pumping device 300 for the cooling cycle system 100 and the heating cycle system 200, which reduces equipment and lowers costs. The operation of the cooling device 110 and / or the heating device 210 can be controlled by a controller, and the operation of the cooling cycle system 100 and the heating cycle system 200 can be adjusted according to actual needs, which simplifies the system and reduces maintenance costs.

[0038] The refrigeration cycle system 100 also includes a first switching valve 140, which is located between the refrigeration unit 110 and the pumping unit 300, and is electrically connected to the controller. Figure 1 and Figure 2 As shown, the first switching valve 140 is located on the first circuit 130, and is used to control the connection and disconnection between the refrigeration unit 110 and the pumping device 300. In cooling mode, the controller controls the first switching valve 140 to open, and the water after heat exchange in the refrigeration unit 110 is pumped to the end user 500 via the pumping device 300. When the refrigeration unit 110 is a ground source heat pump unit, the water temperature can be increased. In this case, in heating mode, the controller controls the first switching valve 140 to open.

[0039] The heating circulation system 200 also includes a second switching valve 240, which is located between the heating device 210 and the pumping device 300, and is electrically connected to the controller. Figure 1 and Figure 2 As shown, the second switching valve 240 is located on the second circuit 230 and is used to control the connection and disconnection between the heating device 210 and the pumping device 300. In cooling mode, the controller controls the second switching valve 240 to close, preventing water in the heating device 210 from flowing to the end user 500. In heating mode, the controller controls the second switching valve 240 to open, and the water heated by the heating device 210 is pumped to the end user 500 via the pumping device 300.

[0040] In one embodiment, the refrigeration unit 110 includes an electric refrigeration unit, and the heating unit 20 includes a boiler. The electric refrigeration unit includes a compressor, an expansion valve, an evaporator, and a condenser connected in sequence. Its principle is to input a certain amount of high-grade energy to the compressor, and the compressor improves the grade of the energy through an isobaric process, so that the energy is transferred from the low-temperature body (evaporator) to the high-temperature body (condenser).

[0041] The refrigeration process is a reverse Carnot cycle. Specifically, the low-temperature, low-pressure refrigerant gas-liquid mixture in the evaporator absorbs heat from the circulating water in the air conditioning system. The circulating water is cooled, and the refrigerant absorbs heat and vaporizes, undergoing an isothermal and isobaric process. After becoming superheated gas at the evaporator outlet, it is drawn into the compressor. Driven by electricity, the compressor raises the low-temperature, low-pressure refrigerant gas to a high-temperature, high-pressure refrigerant gas (energy moves from the low-temperature body to the high-temperature body). In the condenser, the high-temperature, high-pressure refrigerant gas transfers heat to the cooling water, raising its temperature. After undergoing an isothermal and isobaric heat exchange process, the refrigerant becomes a high-temperature, high-pressure refrigerant liquid. After appropriate subcooling, it passes through a throttling device and becomes a low-temperature, low-pressure refrigerant gas-liquid mixture before entering the evaporator. This completes one refrigeration cycle.

[0042] Heating device 210 includes a boiler. The boiler can be a gas-fired boiler, comprising a burner, furnace, boiler drum, water-cooled walls, superheater, economizer, air preheater, steel frame, and furnace walls; specific structural details are not described here. Its working principle is that the gas is fully combusted in the burner to generate heat energy, which is transferred to the water in the boiler through heat exchange, heating the water to produce steam or hot water. The burner mixes the gas with air and ignites it, producing a high-temperature flame that releases heat within the furnace. The furnace provides space for combustion, and the surrounding water-cooled walls absorb heat, causing the water to become a steam-water mixture that enters the boiler drum for steam-water separation. The separated saturated steam enters the superheater and is further heated into superheated steam, which can be used for power generation, industrial production, or heating. Gas-fired boilers are characterized by high efficiency, energy saving, environmental friendliness, cleanliness, and ease of operation.

[0043] like Figure 1As shown, in cooling mode, the controller controls the first switching valve 140 to open and the second switching valve 240 to close. At this time, the water source 400, the electric chiller unit, the pumping device 300, and the end user are connected in sequence. Water enters the chiller unit 110 for heat exchange and is then pumped to the end user 500 by the pumping device 300. In heating mode, the controller controls the second switching valve 240 to open and the first switching valve 140 to close. The water source 400, the boiler, the pumping device 300, and the end user 500 are connected in sequence. Water enters the heating device 210 for heating and is then pumped to the end user 500 by the pumping device 300.

[0044] In another embodiment, the refrigeration unit 110 includes a ground source heat pump unit, and the heating unit 210 includes a boiler. A ground source heat pump unit is a device that uses water circulating in a common pipeline, water drawn from a well, lake, or river, or water circulating in underground coils as a cold (heat) source to produce cold (hot) air or cold (hot) water. It utilizes the exchange of heat between water and geothermal energy (groundwater, soil, or surface water) as a heat source. The ground source heat pump unit exchanges heat with these heat or cold sources by extracting heat from or placing it in a closed heat exchange system at the bottom of the water, in the soil, or in groundwater on the energy harvesting side. In heating mode, the unit harvests heat from the geothermal energy, converts it through a compressor, and then delivers it to the room for heating; in cooling mode, the unit harvests cold energy from the geothermal energy, similarly converting it through a compressor and then delivering it to the room for cooling.

[0045] like Figure 2 As shown, in cooling mode, the controller controls the first switching valve 140 to open and the second switching valve 240 to close. At this time, the water source 400, the ground source heat pump unit, the pumping device 300, and the end user 500 are connected in sequence. After the water enters the cooling unit 110 for heat exchange, it is pumped to the end user 500 by the pumping device 300. In heating mode, the controller controls the first switching valve 140 and the second switching valve 240 to open. The water source 400, the boiler, the pumping device 300, and the end user are connected in sequence. After the water enters the boiler for heating, it is pumped to the end user by the pumping device 300. The water source 400, the ground source heat pump unit, the pumping device 300, and the end user are connected in sequence. After the water enters the ground source heat pump unit for heat exchange, it is pumped to the end user 500 by the pumping device 300.

[0046] like Figure 3 and Figure 4 As shown, the refrigeration cycle system 100 also includes a third switching valve 150, which is located in the first pipeline 120 and is used to control the connection and disconnection between the water source 400 and the refrigeration device 110. The third switching valve 150 is electrically connected to the controller and is linked with the first switching valve 140. Figure 5As shown, the heating circulation system 200 also includes a fourth switching valve 250, which is located in the second pipeline 220 and is used to control the connection and disconnection between the water source 400 and the heating device 210. The fourth switching valve 250 is electrically connected to the controller and is linked with the second switching valve 240.

[0047] Specifically, in cooling mode, the controller opens the first switching valve 140 and the third switching valve 150, and closes the second switching valve 240 and the fourth switching valve 250. In heating mode, if the cooling unit 110 is an electric chiller, the controller closes the first switching valve 140 and the third switching valve 150, and opens the second switching valve 240 and the fourth switching valve 250. If the cooling unit 110 is a ground source heat pump unit, the controller opens the first switching valve 140 and the third switching valve 150, and opens the second switching valve 240 and the fourth switching valve 250. In this mode, both the ground source heat pump unit and the heating unit 210 can provide heating, resulting in high efficiency.

[0048] The refrigeration cycle system 100 also includes a first balancing pipe 160, one end of which is connected to a first pipe 120, and the other end of which is connected to a first circuit 130, to balance the pressure within the first pipe 120 and the first circuit 130. The heating cycle system 200 also includes a second balancing pipe 260, one end of which is connected to a second pipe 220, and the other end of which is connected to a second circuit 230, to balance the pressure within the second pipe 220 and the second circuit 230.

[0049] like Figure 1 and Figure 2 As shown, the first balancing pipe 160 and the second balancing pipe 260 are shared. There is a shared first common pipe between the first pipe 120 and the second pipe 220, and there is a shared second common pipe between the first circuit 130 and the second circuit 230. One end of the balancing pipe is connected to the first common pipe, and the other end of the balancing pipe is connected to the second common pipe.

[0050] The refrigeration cycle system also includes a first pumping element 170, which is located in the first pipeline 120. Specifically, the inlet of the first pumping element 170 is connected to the water source 400, and the outlet of the first pumping element 170 is connected to the inlet of the refrigeration unit 110. Under the action of the first pumping element 170, water is rapidly introduced into the refrigeration unit 110 for heat exchange. A first flow regulating valve is also provided on the first pipeline 120 to regulate the water flow rate into the refrigeration unit 110. A second flow regulating valve is also provided on the first loop 130 to regulate the flow rate from the refrigeration unit 300 to the pumping device.

[0051] The refrigeration cycle system also includes a heat exchanger 190. The refrigeration unit 110 has a first port, a second port, a third port, and a fourth port. A first pipe 120, the first port, the second port, a first loop 130, and a pumping device 300 are sequentially connected to form a first circulation loop. Water undergoes heat exchange within the refrigeration unit 110 and is then pumped to the end user 500 via the pumping device 300. The third port, the inlet of the heat exchanger 190, the outlet of the heat exchanger 190, and the fourth port are sequentially connected to form a second circulation loop. The heat exchanger 190 is used to exchange heat at either the cooling or heating end of the refrigeration unit 110. In the case where the refrigeration unit 110 is an electric refrigeration unit, such as... Figure 2 As shown, the heat exchange device 190 can be a cooling tower 191, such as a water tower. In the case where the refrigeration unit 110 is a ground source heat pump unit, such as... Figure 3 As shown, the heat exchange device 190 is a buried heat exchange pipe that exchanges heat with the soil or groundwater.

[0052] In one embodiment, the refrigeration cycle system further includes a third pumping element 180, which is disposed between the outlet of the heat exchange device 190 and the fourth port. The third pumping element 180 accelerates the heat exchange efficiency. A third flow regulating valve is also provided between the outlet of the heat exchange device 190 and the fourth port to regulate the flow rate of the heat exchange device 190 into the refrigeration device 110. A fourth flow regulating valve is also provided between the inlet of the heat exchange device 190 and the third port to regulate the flow rate of the refrigeration device 110 into the heat exchange device 190.

[0053] like Figure 5 As shown, the heating circulation system 200 also includes a second pumping component 270, which is located in the second pipeline 220. Specifically, the inlet of the second pumping component 270 is connected to the water source 400, and the outlet of the second pumping component 270 is connected to the inlet of the heating device 210. Under the action of the second pumping component 270, the heat-exchanged water quickly enters the refrigeration device 110 for heat exchange. A fifth flow regulating valve is also provided on the second pipeline 220 to regulate the flow rate of water entering the heating device 210. A sixth flow regulating valve is also provided on the second loop to regulate the flow rate from the heating device 210 to the pumping device 300.

[0054] In this embodiment of the present invention, there are multiple refrigeration cycle system 100, heating cycle system 200, and pumping device 300. Each pumping device 300 has a control valve 310 at its inlet, which is used to control the connection and disconnection between the refrigeration device 110 and the pumping device 300, as well as the connection and disconnection between the heating device 210 and the pumping device 300. The control valve 310 is electrically connected to the controller and is used to control at least one control valve 310 to open.

[0055] In one embodiment, the refrigeration cycle system 100 further includes a first main pipeline and a second main pipeline. The inlet of the first main pipeline is connected to a water source 400. The first main pipeline has multiple outlets. One end of each first pipe 120 is connected to one outlet of the first main pipeline, and the other end of the first pipe 120 is connected to a corresponding refrigeration device 110.
