[0002] When the air - conditioning unit needs to be applied in the teaching display of the air force, while meeting the requirements of supply air temperature, air volume, humidity, etc., it is also necessary to maximize the full recovery and utilization of the waste heat generated during the operation of the unit, and at the same time ensure that less power can be consumed to save energy. Content of the Utility Model
[0003] In order to solve the above - mentioned technical problems, the purpose of the utility model is to provide a multi - level utilization system of heat sources for an air - conditioning unit. When it is applied in the teaching display of the air force, because a generator set is adopted, it can ensure the operation and display of the equipment without external power supply, with better flexibility and convenience. At the same time, the multi - level utilization of the heat energy generated by the operation of the generator set (i.e., the engine) can also ensure more energy conservation.
[0004] The utility model provides the following technical solutions:
[0005] A multi - level utilization system of heat sources for an air - conditioning unit includes a box body assembly with casters at the bottom, a generator set, a rotary dehumidifier, and a supply air assembly arranged in the box body assembly. In order to ensure a high degree of integration while reducing the mutual influence between components, the generator set and the rotary dehumidifier are arranged side by side, and the outer wall of the box body assembly and the partition plates arranged inside it form a partition cavity for isolating the rotary dehumidifier. A channel opening communicating with the external environment is also provided on the partition cavity;
[0006] The tail gas generated by the generator set is connected to the air - to - air heater inlet of the rotary dehumidifier, and the outlet of the air - to - air heater is emptied. The rotary dehumidifier's inlet for ambient air connecting to the external environment is connected to the air - to - air heater and the water - to - air pre - heater. The air - to - air heater and the water - to - air pre - heater mainly provide heat sources for the regeneration heating of the rotary dehumidifier. A regeneration fan is arranged at one end of the rotary dehumidifier's rotary wheel body close to the channel opening, and a blower is arranged at the other end. The blower is used to blow air into the supply air assembly. Here, the operation of the rotary dehumidifier belongs to the prior art, that is: the ambient air in the external environment enters one - quarter of the port of the rotary wheel body through the ambient air inlet of the rotary dehumidifier. The regeneration fan and the blower provide driving force for the gas, and the driven air flow then enters the supply air assembly through the other three - quarters of the port of the rotary wheel body. The supply air assembly includes a supply air heater;
[0007] The first-stage circulation pipeline of the circulating hot water of the generator set is connected to the water inlet and outlet of the box heat exchanger at the end of the generator set. Its second-stage circulation pipeline is connected to the water inlet and outlet of the water-air preheater. Its third-stage circulation pipeline is connected to the water inlet and outlet of the air supply heater. The opening and closing of the first-stage circulation pipeline, the second-stage circulation pipeline, and the third-stage circulation pipeline are controlled by their respective solenoid valves. A set of hot water tanks is also installed outside the box body assembly. Water circulation is carried out between the hot water tank and the box heat exchanger through a water pump.
[0008] Thus, when the first-stage circulation pipeline is connected, the circulating hot water of the generator set can enter the box heat exchanger. At the same time, the water pump is started, and the cold water originally filled in the hot water tank can enter the box heat exchanger for heat exchange and then return to the hot water tank to become hot water.
[0009] When the second-stage circulation pipeline is connected, the circulating hot water of the generator set can enter the water-air preheater. At this time, the external ambient air can conduct heat exchange when passing through the water-air preheater, so that the passing air flow becomes hot air. At the same time, because the hot exhaust gas generated by the generator set is connected to the air-air heater, the incoming ambient air can be further heated to provide a heat source for the regeneration of the rotary dehumidifier.
[0010] When the third-stage circulation pipeline is connected, the circulating hot water of the generator set can enter the air supply heater. The air flow blown by the blower can be further heated after passing through the air supply heater. The utilization of the above three-stage heat sources demonstrates the multi-stage utilization of the heat sources generated by the generator set. Its application in the teaching display of the air force can ensure the operation display of the equipment without external power connection because the generator set is adopted, with better flexibility and convenience. At the same time, the multi-stage utilization of heat sources can also ensure more energy conservation.
[0011] Preferably, in order to ensure the height of the air outlet of the air supply component, a set of support plates for supporting the air supply component is also installed in the box body assembly.
[0012] Preferably, a faucet is installed on the hot water tank. At this time, personnel can directly use the hot water by opening the faucet, which is more convenient.
[0013] The beneficial effects of the present invention are as follows: The multi-stage heat source utilization system of an air-conditioning unit of the present invention is applied in the teaching display of the air force. Because the generator set is adopted, the operation display of the equipment can be guaranteed without external power connection, with better flexibility and convenience. At the same time, the multi-stage utilization of heat sources can also ensure more energy conservation. Description of the Drawings

In order to ensure a high degree of integration while also reducing the mutual influence between each component, the generator set 3 and the rotary wheel dehumidifier 4 are arranged side by side, and a partition cavity for isolating the rotary wheel dehumidifier 4 is formed by the outer wall of the box body assembly 2 and the partition board 6 arranged therein. A passage opening 7 communicating with the external environment is also opened on the partition cavity;
[0022] The exhaust gas generated by the generator set 3 is connected to the air inlet of the air-air heater 41 of the rotary wheel dehumidifier 4, and the air outlet of the air-air heater 41 is vented. The rotary wheel dehumidifier 4 is used to connect the air inlet of the ambient air from the external environment to the air-air heater 41 and the water-air preheater 42. A regeneration fan 44 is provided at one end of the rotary wheel body 43 of the rotary wheel dehumidifier 4 close to the channel port 7, and a blower 45 is provided at the other end. The blower 45 is used to blow air into the air supply assembly 5. Here, the operation of the rotary wheel dehumidifier 4 belongs to the prior art, that is, the ambient air from the external environment enters the port at one quarter end of the rotary wheel body 43 through the ambient air inlet of the rotary wheel dehumidifier 4. The regeneration fan 44 and the blower 45 provide driving force for the gas, and the driven air flow then enters the air supply assembly 5 through the port at the other three quarters end of the rotary wheel body 43. The air supply assembly 5 includes an air supply heater;
[0023] The first-stage circulation pipeline of the circulating hot water of the generator set 3 is connected to the water inlet and outlet of the box-type heat exchanger 8 at the end of the generator set 3. Its second-stage circulation pipeline is connected to the water inlet and outlet of the water-air preheater 42. Its third-stage circulation pipeline is connected to the water inlet and outlet of the air supply heater. And the first-stage circulation pipeline, the second-stage circulation pipeline and the third-stage circulation pipeline are controlled to open and close by their respective solenoid valves.

[0026] The working principle of the present utility model is as follows: So far, when the first-stage circulation pipeline is connected, the circulating hot water of the generator set 3 can enter the box-type heat exchanger 8. At the same time, the water pump 11 is started, and the cold water originally filled in the hot water tank 9 can enter the box-type heat exchanger 8 for heat exchange and then return to the hot water tank 9 to become hot water;
[0027] When the second-stage circulation pipeline is connected, the circulating hot water of the generator set 3 can enter the water-air preheater 42. At this time, the external ambient air can carry out heat exchange when passing through the water-air preheater 42, so that the passing air flow becomes hot air. At the same time, because the hot exhaust gas generated by the generator set 3 is connected to the air-air heater 41, the entering ambient air can be further heated, providing a heat source for the rotary wheel dehumidification regeneration;
[0028] When the third-stage circulating pipeline is connected, the circulating hot water of the generator set 3 can enter the air supply heater, and the air flow blown by the blower 45 can be further heated after passing through the air supply heater.
