Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and particularly relates to an enthalpy-increasing compressor and an air conditioner. Background Art

[0002] In the refrigeration / heating cycle, the subcooled liquid coming out of the condenser becomes a gas-liquid mixture after passing through a pressure reducing device and enters the evaporator. The gas injection enthalpy-increasing technology reduces the proportion of gas entering the evaporator, thereby increasing the refrigeration capacity / heating capacity and improving the energy efficiency.

[0003] For the gas injection enthalpy-increasing technology, a roller reciprocating operation is usually used to open and close the gas injection port. This structure has high requirements for the space of the structure. If the gas injection port is set too small, the enthalpy-increasing effect is not good; if it is set too large, leakage and backflow are likely to occur; and the opening and closing angles of the gas injection port cannot be adjusted according to the change of working conditions, and the effect is poor when the working conditions deviate far from the designed working conditions.

[0004] Due to the technical problem that the gas injection port of the gas injection enthalpy-increasing compressor in the prior art cannot adjust the size and / or opening / closing angle of the gas injection port according to the change of working conditions, resulting in poor gas injection effect when the working conditions deviate far from the designed working conditions, the utility model researches and designs an enthalpy-increasing compressor and an air conditioner. Summary of the Utility Model

[0038] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0039] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. are usually based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.
