See Figures 3 to 5. 3 is a schematic structural view of a multi-channel microtube heat exchanger 11 according to the present invention. Fig. 4 is a partial enlarged view of a portion A in Fig. 3. Figure 5 is a cross-sectional view of the refrigerant line 21 in the multi-channel microtube heat exchanger 11 in accordance with the present invention. The multi-channel microtube heat exchanger 11 includes a plurality of refrigerant tubes 21 which are in the shape of a coil and which are provided with a water pipe 22 for heat exchange therewith. The water pipe 22 is provided with a heating passage formed by the water inlet 11c and the water outlet l id, so that the water in the water pipe 22 passes through the multi-channel micro-tube heat exchanger 11 to exchange heat to hot water, and flows out from the water outlet l id for supply. use. A thermostat 17 is installed on the water outlet l id to control the outlet water temperature within a prescribed range. In the present invention, a sleeve 23 for preventing refrigerant from leaking into the water is provided between the refrigerant pipe 21 and the water pipe 22, and a refrigerant leakage alarm device 7 is provided at the end of the casing 23. When the refrigerant line 21 leaks, the refrigerant enters the sleeve 23 and is alarmed by the refrigerant leakage alarm device 7 at the end of the sleeve 23 to ensure that the water is free from contamination and safer to use. The refrigerant inlet 8 is provided at the refrigerant inlet end 11a of the multi-channel microtube heat exchanger 11 to make the refrigerant entering the plurality of refrigerant lines 21 more uniform and to increase the pressure. In the present invention, in order to enable the compressor 10 to be quickly turned on, the power is turned on frequently, and the standby time after the shutdown is shortened, at the refrigerant outlet end 13b of the air-cooled evaporator 13 and the refrigerant discharge end 9d of the flow dividing device 9. An instantaneous pressure balancer 16 is also connected across. The flow dividing device 9 can be realized by an electromagnetic four-way valve, but the invention is not limited thereto. Those skilled in the art will appreciate that other shunting devices, proportional valves, etc. that meet the functional requirements of the present invention can be used. The first high temperature gas from the first refrigerant outlet end 9b of the flow dividing device 9 enters the multi-channel microtube heat exchanger 11, more The outside of the refrigerant line 21 in the passage microtube heat exchanger 11 is covered with a water pipe 22 for heat exchange therewith. When the water pipe 22 has water flowing, the high-temperature refrigerant in the refrigerant pipe 21 transfers heat to the water to be used as hot water. The indoor fan 12 supplies the second high-temperature refrigerant gas from the second refrigerant outlet end 9c of the flow dividing device 9 to heat exchange with the indoor air to provide heating. The refrigerant liquid subjected to heat exchange by the multi-channel microtube heat exchanger 11 and the indoor fan 12 is sent to the air-cooled evaporator 13. In the air-cooled evaporator 13, the refrigerant gas evaporates to become a gas, and is sucked by the compressor 10, and is compressed to become a high-temperature high-pressure refrigerant gas. In this way, by continuously circulating, hot water and heating can be continuously supplied for use at the same time.

The present invention is exemplified by bridging the instantaneous pressure balancer 16 between the refrigerant outlet end 13b of the air-cooled evaporator 13 and the refrigerant discharge end 9d of the flow dividing device 9, but it should be understood by those skilled in the art. Other connection means are also possible, for example, bridging the instantaneous pressure balancer 16 between the refrigerant outlet end 13b of the air-cooled evaporator 13 and the refrigerant outlet end 10a of the compressor 10. The present invention is provided with a supercharging device 8, and as shown in Figs. 3 and 4, the refrigerant entering the refrigerant line 21 is made more uniform, and a plurality of refrigerant lines 21 are installed in the water pipe 22. The surfaces of the refrigerant pipe 21 and the water pipe 22 are made uneven, whereby the water in the refrigerant pipe 21 and the water pipe 22 can be turbulent during use, so that heat can be quickly transferred, and excellent heat transfer efficiency can be achieved. Further, a thermostat 17 is disposed on the water outlet l id of the water pipe 22, and the water temperature is monitored by the temperature sensor and the flow rate of the refrigerant in the refrigerant pipe 21 is controlled by the control circuit to achieve the purpose of controlling the water temperature. The multi-channel microtube heat exchanger 11 is provided with a leak-proof casing 23 which prevents refrigerant and oil from entering the water when the refrigerant pipe 21 leaks during operation to ensure the safety of the user. As shown in Figs. 3 and 4, the refrigerant leakage alarm device 7 is a sleeve that is outside the end of the refrigerant line 21 to isolate the water tube 22 from the refrigerant line 21. When the refrigerant pipe leaks, the refrigerant and the refrigerating oil enter the casing 23. When the refrigerant accumulates more, for example, when the pressure exceeds O.OlMPa, the pressure sensing system can cause the system to alarm to ensure safe use. According to another embodiment of the invention, wherein the multi-channel microtube heat exchanger comprises at least three refrigerant lines 21 in parallel. Although three parallel refrigerant lines 21 are taken as an example in FIG. 4, those skilled in the art can understand that the present invention is not limited thereto, and four, five, six or more parallel or serial/parallel refrigerant tubes are not limited thereto. Road 21 is possible. Further, the cross section of the plurality of refrigerant lines 21 is not limited to a circular shape, and different diameters and/or cross sections may be employed as long as the heat exchange parameter requirements of the present invention are satisfied. The indoor fan 12 of the present invention may be an indoor fan of a general air conditioner, or a fan specially designed to exchange heat with indoor air, and the invention is not limited thereto. The air-cooled evaporator 13 of the present invention may be a corresponding device of a conventional air conditioner (such as a radiator of an outdoor unit of a split air conditioner), or a specially designed air-cooled evaporator, and the invention is not limited thereto.
