Description

Technical Field

[0001] This utility model relates to the field of heating technology, and in particular to a novel heating device. Background Technology

[0002] my country has a vast territory with significant temperature differences between the north and south. In the hot summer, densely populated places such as schools, hospitals, hotels, and factories often use screw-type water-cooled central air conditioning for centralized cooling. In the cold winter, northern regions with the necessary resources have implemented centralized heating using natural gas or coal. While winters in most parts of southern my country are not particularly cold and the duration is short, so heating is rarely considered in winter, the damp and chilly climate in the south makes short-term heating a necessity.

[0003] Therefore, a new type of heating equipment is urgently needed to solve the above problems. Utility Model Content

[0027] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0028] Please refer to Figure 1 This utility model provides a novel heating device, including a screw chiller unit, a hot water tank 1, a hot water pump 3, a heat exchange return water pipe 10, and a first valve 11. The screw chiller unit includes an outlet pipe 5, a return water pipe, a bypass pipe 17, a fan coil unit, an air conditioning water distributor 6, and a condenser / evaporator 16 connected sequentially through the outlet pipe 5, and a chilled water pump 4 and an air conditioning water collector 8 connected sequentially through the return water pipe. The outlet pipe 5 is connected to the return water pipe via the bypass pipe 17 and the condenser / evaporator 16. The hot water pump 3 is installed between the inlet of the hot water tank 1 and the inlet of the chilled water pump 4. The heat exchange return water pipe 10 is installed between the return water pipe and the hot water tank 1. The first valve 11 is installed on the heat exchange return water pipe 10 and is used to close and open the heat exchange return water pipe 10. Specifically, during heating, water in the hot water tank 1 is pumped to the cold water pump 4 by the hot water pump 3, then enters the air conditioning distributor 6 through the bypass pipe 17, and then dissipates heat through the fan coil unit. Afterwards, it flows into the air conditioning water collector 8 through the return water pipe, and then returns to the hot water tank 1 through the heat exchange return water pipe 10, thus achieving heating. During cooling, the screw chiller unit operates, and the chilled water produced by the condenser-evaporator 16 flows to the air conditioning distributor 6 through the outlet pipe 5, then absorbs heat through the fan coil unit, and then flows into the air conditioning water collector 8 through the return water pipe. Finally, it returns to the condenser-evaporator 16 through the cold water pump 4 for cooling, thus achieving cooling.

[0029] The novel heating equipment provided by this utility model achieves heating effect by connecting a hot water tank 1, a hot water pump 3, a heat exchange return water pipe 10, and a first valve 11 to an existing screw chiller unit. It has a simple structure, is easy to implement, and has a low cost.

[0030] Optionally, a thermostat 12 is also included. The thermostat 12 is installed on the return water pipe of the screw chiller and is communicatively connected to the first valve 11. The thermostat 12 is used to detect the return water temperature of the screw chiller. The first valve 11 opens and closes the heat exchange return water pipe 10 according to the return water temperature. Specifically, when the return water temperature detected by the thermostat 12 is lower than the preset temperature (e.g., 40°C), the first valve 11 opens to allow the return water in the air conditioning water collector 8 to enter the hot water tank 1. Then, the hot water pump 3 is started to replenish the hot water in the hot water tank 1 to the fan coil unit for heating.

[0031] Optionally, the hot water tank 1 is a power plant condensate tank, allowing the power plant's own condensate tank to be connected to an existing screw-type water-cooled unit for heating, thus further simplifying the structure. Of course, in other embodiments, wherever a hot water boiler is available (e.g., a hospital), local resources can be used to connect the hot water generated by the boiler to an existing screw-type water-cooled unit for heating. Furthermore, in cases of high demand where existing boiler equipment is unavailable, a separate boiler can be installed to provide hot water for the novel heating equipment provided in this embodiment.

[0032] Optionally, the system also includes a waste steam pipe 15, which connects to the power plant's condensate drain tank to heat the water inside. The water temperature in the drain tank is typically around 60°C. The waste steam pipe 15 introduces waste steam into the drain tank to reheat the water, raising its temperature to over 80°C. This ensures the temperature at the fan coil unit remains above 30°C, thus guaranteeing effective heating.

[0033] Optionally, the return water pipeline includes a first return water pipe 91, a second return water pipe 92, and a third return water pipe 93.

[0034] One end of the first return water pipe 91 is connected to the outlet of the fan coil unit, and the other end is connected to the air conditioner water collector 8.

[0035] One end of the second return water pipe 92 is connected to the air conditioner water collector 8, and the other end is connected to the inlet of the chilled water pump 4. One end of the third return water pipe 93 is connected to the outlet of the chilled water pump 4, and the other end is connected to the inlet of the bypass pipe 17 and the inlet of the condenser evaporator 16.

[0036] Optionally, the system also includes a second valve 18, a third valve 71, and a fourth valve 72. The second valve 18 is installed on the bypass pipe 17 to control the opening and closing of the bypass pipe 17. The third valve 71 is installed at the inlet end of the condenser evaporator 16 to control the opening and closing of the inlet end of the condenser evaporator 16. The fourth valve 72 is installed at the outlet end of the condenser evaporator 16 to control the opening and closing of the outlet end of the condenser evaporator 16. When heating is started, the second valve 18 is opened, and the third valve 71 and the fourth valve 72 are closed.

[0037] Optionally, it also includes a hot water pipe 2, one end of which is connected to the hot water tank 1, and the other end of which is connected to the inlet of the cold water pump 4. The hot water pump 3 is installed on the hot water pipe 2 to control the on / off state of the hot water pipe 2.

[0038] Optionally, it also includes a pressure balancing pipe 13 and a pressure balancing valve 14. One end of the pressure balancing pipe 13 is connected to the air conditioner water distributor 6, and the other end of the pressure balancing pipe 13 is connected to the air conditioner water collector 8. The pressure balancing valve 14 is installed on the pressure balancing pipe 13 and is used to control the opening of the pressure balancing pipe 13, thereby adjusting the pressure difference between the air conditioner water collector 8 and the air conditioner water distributor 6, and avoiding an excessive pressure difference between the air conditioner water collector 8 and the air conditioner water distributor 6.

[0039] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
