Provided is an air conditioning refrigeration system. An outlet of a high-back-pressure rotary compressor is connected with an inlet of a condenser, an outlet of the condenser is connected with a liquid inlet of a heat regenerator, a liquid outlet of the heat regenerator is connected with an inlet of an expansion valve, an outlet of the expansion valve is connected with an inlet of an evaporator, an outlet of the evaporator is connected with a gas inlet of the heat regenerator, and a gas outlet of the heat regenerator is connected with an inlet of the high-back-pressure rotary compressor. Refrigerating fluid enters the high-back-pressure rotary compressor firstly, and is compressed into high-temperature high-pressure gas entering the condenser, the gas is condensed into intermediate-temperature high-pressure liquid, and heat is discharged into air. The refrigerating fluid flows through the heat regenerator and enters the expansion valve, and is throttled to be in a low-temperature low-pressure gas-liquid mixing state, then the refrigerating fluid enters the evaporator, heat exchange is carried out on the refrigerating fluid and the air in the environment, the temperature of the air is reduced, and therefore the refrigeration effect is achieved. According to the system, efficiency and stability are improved, oil return is good, the probability of blocking capillary tubes is reduced, and the injection amount of the refrigerating fluid is reduced.

The compressor set comprises a plurality of compressors, a set air suction end and a plurality of electrical boxes, wherein the compressors are connected in parallel; the set air suction end is connected with an air inlet of the outermost compressor; and the set air suction end is adjacent to a high-temperature side of the nearest electrical box to achieve a heat dissipation purpose for the electrical box.

The invention discloses a flooded vortex heat-pump hot-water machine comprising a scroll compressor, an oil separator, a condenser, a plate-type evaporator, an electronic expansion valve, a flooded evaporator, a capillary tube and an aspirating tube. The scroll compressor, the oil separator, the condenser, the plate-type evaporator, the electronic expansion valve, the flooded evaporator and the aspirating tube are sequentially communicated end to end through pipelines. The middle or lower parts of an inner pipeline of the flooded evaporator are communicated with the plate-type evaporator through the capillary tube, and one side of the upper end of the plate-type evaporator is further communicated with the aspirating tube. By the adoption of the structure that the plate-type evaporator is connected with the flooded evaporator through the capillary tube, the problem that recycling of lubricating oil is difficult in the scroll compressor mounted in an air source heat pump group is solved. By the adoption of the double-evaporator structure, chilled water consumption of the flooded evaporator is reduced through shunt of the plate-type evaporator, suction temperature is raised, temperature difference of exhaust and suction is reduced, and input power when the compressor operates is lowered.

The invention discloses a rotary compressor. The rotary compressor comprises an electric structure part and a compressing structure part, wherein the electric structure part comprises a stator and a rotor which are fixedly arranged inside a machine enclosure; the compressing structure part comprises a circular cylinder fixedly arranged on the inner circumference surface of the machine enclosure, as well as an upper bearing and a lower bearing which are tightly attached to the upper and the lower side surfaces of the cylinder and through which a crankshaft penetrates to be supported at the same time; a through hole for penetrating through the upper bearing is formed in an air suction port of the compressor; and the diameter of the through hole is 0.8-1.2mm. According to the compressor disclosed by the invention, during the air suction process of the compressor, a small amount of high temperature gas enters the interior of the cylinder from the through hole, so that the air suction temperature of the compressor is increased, the enthalpy gain effect is achieved, and the exhaust temperature is prevented from being overhigh; and while the air suction capacity of the compressor is improved, the high temperature gas sucked from the through hole is directly merged with a cooling medium entering from the air suction port, so that liquid drops mixed in the sucked cooling medium can be vaporized, liquid hammer is prevented, and the cylinder is prevented from being damaged.
