Problems solved by technology
Although the invention does not require external power supply, a large amount of liquid carbon dioxide is required to maintain the temperature in the cabin for a long time, and high-pressure steel cylinders are required to store liquid carbon dioxide, and when the external temperature is high, it is very easy to cause the temperature rise and gasification of liquid carbon dioxide
In addition, the safety of the high-pressure steel cylinder itself, as well as the underground transportation and regular inspection are all current problems

Embodiment Construction
[0027] The following is a detailed description of the embodiments of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following Example.
[0028] Such as figure 1 As shown, an air-conditioning and refrigeration system without external power supply for mine software rescue cabin 1 includes a circulating refrigeration system with R134a as a working medium, and a generator-battery power system. The R134a refrigeration system and the power system are coupled together to form a total energy system to jointly adjust the temperature of the air in the cabin.
[0029] The R134a circulating refrigeration system is a closed system, which specifically includes a handle 2, a manual compressor 4, a refrigerant pipeline 5, a condenser 7, a capillary tube 9, and a thi...

The invention discloses a non-external-power-supply air-conditioning / refrigerating system for soft escape capsules for mines, which comprises a closed cycle refrigeration system for refrigerant working media and a power storage system comprising an electric generator and a storage battery, and is not required to be provided with any external power supply; the cycle refrigeration system is a closed system, comprises a compressor, an indoor evaporator, a capillary tube and an outdoor condenser, and is connected by a refrigerant pipeline; and the power storage system comprising an electric generator and a storage battery comprises a manual transmission mechanism, a direct-current electric generator, a storage battery and a fan. When a person does work in an escape capsule, the electric generator drives the fan in the cycle refrigeration system, and charges the storage battery; and when the person in the escape capsule has a rest, the electric generator is used as an actuating unit and depends on the storage battery for power supply, and drives the compressor to operate; and meanwhile, the storage battery also supplies power for the fan so as to maintain the normal operation of the cycle refrigeration system. Refrigeration cycle and power cycle are mutually coupled so as to adjust the air temperature in an escape capsule together.
Description
technical field [0001] The invention relates to an air-conditioning and refrigeration system, which is specifically applied to an air-conditioning and refrigeration system without external power supply in a coal mine underground software rescue cabin, including a closed-cycle refrigeration system of refrigerant working medium and a power storage system composed of a generator and a storage battery. No need for any external power supply. Background technique [0002] When a catastrophic accident occurs underground in a coal mine, different levels of life-saving systems are provided to underground operators. Generally, the first level is the underground chamber, which will have relatively complete materials and equipment, and will supply power and water from the outside. When a mining disaster occurs, underground operators can stay here for a long time, but the investment in the chamber is large, and To communicate with the outside world. The second level is the hard cabin o...
