Description

Technical Field

[0001] This utility model belongs to the technical field of airport ground support equipment, specifically relating to a closed-loop integrated energy exchange device. Background Technology

[0002] Currently, existing airport ground support air-liquid integrated equipment can simultaneously provide air conditioning and liquid cooling support for aircraft. It has two independent refrigeration systems: one for air conditioning and cooling supply, and the other for liquid cooling and cooling supply. Because these are two independent systems, a 5-10kW margin is added to the actual required cooling capacity when selecting compressors to ensure adequate cooling output under extreme conditions. For example, if the air supply system requires 50kW of cooling capacity, the selected compressor would need a capacity of 55-60kW under standard conditions. Because the equipment has two refrigeration systems, the overall cooling capacity is 10-20kW larger than the actual requirement, which is relatively wasteful. Furthermore, increasing the compressor size requires correspondingly larger heat exchangers and electrical components, which is extremely uneconomical. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the technical solution adopted by this utility model is: a closed-loop integrated energy exchange device, including a cold storage box and a heat exchange body disposed in the cold storage box. The heat exchange body includes a first compressor refrigerant main inlet pipe, a second compressor refrigerant main inlet pipe, a first compressor refrigerant main outlet pipe, a second compressor refrigerant main outlet pipe, an air supply circulation antifreeze main outlet pipe, a liquid supply circulation antifreeze main outlet pipe, an air supply circulation antifreeze main inlet pipe, a liquid supply circulation antifreeze main inlet pipe, a liquid supply circulation antifreeze main inlet pipe, multiple first compressor refrigerant branch pipes, multiple second compressor refrigerant branch pipes, and multiple... The system includes an air-circulating antifreeze branch pipe and multiple liquid-circulating antifreeze branch pipes. The two ends of the first compressor refrigerant branch pipe are connected to the first compressor refrigerant main inlet pipe and the first compressor refrigerant main outlet pipe, respectively. The two ends of the second compressor refrigerant branch pipe are connected to the second compressor refrigerant main inlet pipe and the second compressor refrigerant main outlet pipe, respectively. The two ends of the air-circulating antifreeze branch pipe are connected to the air-circulating antifreeze main outlet pipe and the air-circulating antifreeze main inlet pipe, respectively. The liquid-circulating antifreeze branch pipes are connected to the liquid-circulating antifreeze main outlet pipe and the liquid-circulating antifreeze main inlet pipe, respectively.

[0005] The cold storage box is covered with a cold storage box cover, which is equipped with an exhaust valve and a temperature sensor.

[0006] The cold storage box is equipped with a cold storage liquid pipe.

[0007] A cold storage water receiving tray is installed below the cold storage box.

[0008] The cold storage tank is equipped with a level gauge.

[0009] Compared with existing technologies, this invention has the following advantages: This invention allows the air conditioning refrigeration supply system and the liquid-cooled refrigeration supply system to share a cold source, storing all the cooling capacity generated by the compressor in a closed-loop integrated energy exchange device. The cooling capacity is then distributed according to usage requirements, preventing waste. Simultaneously, the refrigerant in the closed-loop integrated energy exchange device can store excess cooling capacity during operation and release it when needed, reducing the demand on the compressor's cooling capacity. When selecting a compressor, only a specification with a cooling capacity matching the requirements needs to be chosen, indirectly reducing the overall power consumption of the unit.

[0016] See Figures 1-4A closed-loop integrated energy exchange device includes a cold storage tank 1 and a heat exchange body 2 disposed within the cold storage tank 1. The heat exchange body 2 includes a first compressor refrigerant main inlet pipe 101, a second compressor refrigerant main inlet pipe 102, a first compressor refrigerant main outlet pipe 103, a second compressor refrigerant main outlet pipe 104, a supply air circulation antifreeze main outlet pipe 105, a supply liquid circulation antifreeze main outlet pipe 106, a supply air circulation antifreeze main inlet pipe 107, a supply liquid circulation antifreeze main inlet pipe 108, multiple first compressor refrigerant branch pipes 109, multiple second compressor refrigerant branch pipes 1010, multiple supply air circulation antifreeze branch pipes 1011, and multiple... A liquid-supply circulating antifreeze branch pipe 1012 is connected to the first compressor refrigerant branch pipe 109, with its two ends connected to the first compressor refrigerant main inlet pipe 101 and the first compressor refrigerant main outlet pipe 103, respectively. The two ends of the second compressor refrigerant branch pipe 1010 are connected to the second compressor refrigerant main inlet pipe 102 and the second compressor refrigerant main outlet pipe 104, respectively. The two ends of the air-supply circulating antifreeze branch pipe 1011 are connected to the air-supply circulating antifreeze main outlet pipe 105 and the air-supply circulating antifreeze main inlet pipe 107, respectively. The liquid-supply circulating antifreeze branch pipe 1012 is connected to the liquid-supply circulating antifreeze main outlet pipe 106 and the liquid-supply circulating antifreeze main inlet pipe 108, respectively.

[0017] The first compressor refrigerant inlet pipe 101 and the first compressor refrigerant outlet pipe 103 are connected to the first compressor, and the second compressor refrigerant inlet pipe 102 and the second compressor refrigerant outlet pipe 104 are connected to the second compressor.

[0018] The antifreeze supply circulation branch pipe is located between the two compressor refrigerant branches. The two compressor refrigerant branches can both be refrigerant branches of the first compressor, or both be refrigerant branches of the second compressor, or one first compressor refrigerant branch pipe and one second compressor refrigerant branch pipe.

[0019] The air supply circulation antifreeze branch pipe is located between the two compressor refrigerant branch pipes. The two compressor refrigerant branch pipes can both be refrigerant branch pipes of the first compressor, or both be refrigerant branch pipes of the second compressor, or they can be one refrigerant branch pipe of the first compressor and one refrigerant branch pipe of the second compressor.

[0020] The compressor refrigerant pipes, the liquid supply circulation antifreeze pipes, and the air supply circulation antifreeze pipes are interspersed, which can facilitate rapid and efficient heat exchange.

[0021] The cold storage tank 1 is covered with a cold storage tank cover 3, on which an exhaust valve 4 and a temperature sensor 5 are installed. The exhaust valve is used for venting the cold storage tank when adding cold storage liquid and for venting the cold storage tank during normal operation of the unit. The temperature sensor is used to detect the real-time temperature of the cold storage liquid in the cold storage tank, thereby controlling the start and stop of the compressor.

[0022] The cold storage tank 1 is equipped with a cold storage liquid pipe 6. The cold storage liquid pipe is used to add or discharge cold storage liquid into the cold storage tank.

[0023] A cold storage water collection tray 7 is installed below the cold storage box 1. The cold storage water collection tray is used to collect the generated condensate and discharge the condensate to a fixed water tank through a water pipe.

[0024] A level gauge 8 is installed on the cold storage tank 1. The level gauge is used to display the liquid level of the cold storage liquid in the tank, reminding the user whether the cold storage liquid needs to be replenished. The cold storage liquid is a constant-temperature phase change material used to store excess cold energy during emergency supply. It is liquid at room temperature, changes from liquid to solid after absorbing cold energy, and changes back to liquid after releasing cold energy.

[0025] When this utility model is in operation, cold storage liquid is injected into the cold storage tank. The refrigerant in the first compressor refrigerant main inlet pipe 101 and the second compressor refrigerant main inlet pipe 102 enters the corresponding compressor refrigerant branch pipe. The refrigerant in the compressor refrigerant branch pipe exchanges heat with the cold storage liquid, transferring the cold energy to the cold storage liquid. The cold storage liquid then exchanges heat with the supply liquid circulation antifreeze branch pipe and the air supply circulation antifreeze branch pipe, transferring the cold energy to the antifreeze in the supply liquid circulation antifreeze branch pipe and the air supply circulation antifreeze branch pipe.

[0026] This invention allows the air conditioning refrigeration supply system and the liquid-cooled refrigeration supply system to share a cold source. All the cooling capacity generated by the compressor is stored in a closed-loop integrated energy exchange device, and then distributed according to usage requirements, preventing waste of cooling capacity. Simultaneously, the refrigerant in the closed-loop integrated energy exchange device can store excess cooling capacity during operation and release it when needed, reducing the demand on the compressor. When selecting a compressor, only a specification with a cooling capacity matching the requirements needs to be chosen, indirectly reducing the overall power consumption of the unit.
