The invention discloses an air conditioner heat exchange pad system. The system comprises a refrigerant circulation system, a medium circulation system and a heat storage member; a refrigerant is circulated in the refrigerant circulation system; the medium circulation system involves a heat exchange pad and a medium containing part, wherein the heat exchange pad comprises a pad body and a medium circulation pipe, a part of the medium circulation pipe is arranged in the pad body in a penetrating mode, the medium circulation pipe is in communication with the medium containing part, and a mediumin the medium containing part exchanges heat with the refrigerant in the refrigerant circulation system; and the heat storage member is connected with the medium containing part. According to the airconditioner heat exchange pad system, the refrigerant is utilized to perform heat exchange with the medium, when the medium flows through the heat exchange pad, the temperature of the heat exchange pad can be changed, the overall energy consumption is low, and the safety is high; and the arranged heat storage member is beneficial to reducing the energy consumption of the device on one aspect and also can prevent the temperature fluctuation of the medium in the heat exchange process from being too large on the other aspect.

A kitchen air adjusting system comprises an air adjusting assembly and a cooking fume suction assembly. A compressor, a first heat exchanger and a second heat exchanger of the air adjusting assembly communicate through a refrigerant pipeline. The cooking fume suction assembly is provided with a smoke exhaust channel. The kitchen air adjusting system is characterized in that the air adjusting assembly comprises a shell, and an air inlet, a first air outlet and a second air outlet are formed in the shell; the first air outlet communicates with the interior of a kitchen, and the second air outletcommunicates with the smoke exhaust channel through an air outlet channel; and the first exchanger is mounted in the shell and located in an air channel between the air inlet and the first air outlet, a first heat exchange unit is mounted in an air outlet channel, and a second heat exchange unit is mounted in the smoke exhaust channel. The kitchen air adjusting system has the advantages that theair amount of the first heat exchange unit and the air amount of the second heat exchange unit are form an air conditioner indoor unit and an extractor hood correspondingly, the first heat exchange unit and the second heat exchange unit can be independent and can also be combined into a heat exchanger, use is flexible, and the heat exchange effect is good.

The invention provides a low-temperature refrigeration method and system. According to the method, a refrigerant compression type refrigeration system or other cold sources are used for cooling compressed gas to serve as inlet gas of a vortex tube, low-temperature exhaust gas at the cold end of the vortex tube is used for refrigeration, and the vortex tube and the refrigerant compression type refrigeration system or other cold sources can operate at the same time or operate in sequence. The efficiency of an air compressor is related to the refrigeration efficiency of the vortex tube, the energy consumption of the air compressor is high, especially the efficiency of a small-sized miniature air compressor is lower, and the refrigeration efficiency of the vortex tube is low, so that the efficiency of the air compressor is improved, and the energy consumption of the air compressor is reduced, namely the efficiency of the air compressor is improved by reducing the inlet air temperature of the air compressor, and meanwhile, energy consumption of the air compressor is reduced by reducing the pressure of the air compressor. The low-temperature refrigerating system has the characteristics of high efficiency, high reliability, low energy consumption, low cost and the like, and the low-temperature refrigerating system which is originally limited to special occasions can be applied to common wide fields including various fields of industry, agriculture, commercial use, civil use and the like.

The invention provides a thermal energy utilization system. The system comprises an evaporator, an expansion machine, a condenser, a preheater and an executing assembly, wherein a first port of the evaporator is used for being connected with a to-be-recovered heat source; a second port of the evaporator communicates with the inlet end of the expansion machine, so that a refrigerant medium pressurized by the evaporator is enabled to flow into the expansion machine; the outlet end of the expansion machine communicates with the inlet end of the condenser; the outlet end of the condenser communicates with the inlet end of the preheater, the outlet end of the preheater communicates with a third port of the evaporator, therefore, the refrigerant medium flows into the evaporator after passing through the preheater, and the evaporator, the expansion machine, the condenser, the preheater and the evaporator are sequentially connected to form a circulation loop; and an output shaft of the expansion machine is connected with the executing assembly, the executing assembly is driven to operate by the expansion machine and enabled to do external work, and the problem of low waste heat utilizationrate of a boiler in the prior art is solved.
