Disclosed in the present invention are a zero-load output non-stop control method and apparatus, and a unit. The apparatus comprises: a three-way valve, provided at an exhaust port of a compressor; a mixing tank, provided between an air suction port of the compressor and a condenser and used for mixing a refrigerant discharged by the compressor with a refrigerant throttled by the condenser; a first electronic expansion valve, provided on a first pipeline from the condenser to the mixing tank and sued for controlling the amount of the refrigerant throttled by the condenser and entering the mixing tank; and an electromagnetic valve, provided on a second pipeline between the three-way valve and the mixing tank and used for controlling the amount of the refrigerant discharged by the compressor and directly entering the mixing tank.

Zero-load output non-stop control method and apparatus, and unit

A compressor, including: a first rotor being rotatable around a first axis, the first rotor including a first portion and a second portion; and a first shaft carrying the first portion and the second portion, the first shaft having a first end and a second end that are oppositely arranged. The first rotor is configured to be applied with a preset acting force in a direction from the first end toward the second end or from the second end toward the first end during rotation. The size of the compressor can be reduced with the displacement of the compressor remaining substantially unchanged.

Rotor assembly, compressor and air conditioner

The present disclosure provides a compressor and an air conditioner. The compressor includes a housing; a first rotating shaft mounted in the housing; a connecting assembly sleeved on the first rotating shaft; and a first rotor assembly including a first rotor and a second rotor coaxially disposed on the connecting assembly. The connecting assembly carries the first rotor and the second rotor to rotate about the first rotating shaft together. The connecting assembly is configured to limit the relative positions of the first rotor and the second rotor, such that there exists a clearance between the first rotor and the second rotor. The present disclosure can maintain a clearance between the first rotor and the second rotor without increasing the number of components of the compressor.

A rotor assembly, a compressor and an air conditioner are provided. The rotor assembly includes a first rotation shaft and a first rotor rotatably arranged on the first rotation shaft. The first rotor includes a plurality of first screw blades, and a first tooth slot is formed between two adjacent first screw blades; a suction end of the first rotor has at least one oil slinger slot, to allow a lubricant to enter the first tooth slot through the at least one oil slinger slot. It is ensured that the lubricant can fully lubricate and seal the first tooth slot, so that the compressor can run more smoothly, reduce wear of screw blades and improve the service life of the compressor.

Provided is a rotor structure of a screw compressor and an inverter screw compressor with the same. The rotor structure includes: a female rotor including a female rotor body, wherein the female rotor body includes a plurality of female teeth, and a tooth profile is formed between tooth crests of two adjacent female teeth of the female rotor body, and the tooth profile is formed by sequentially connecting an arc segment ab an envelope bc, an arc segment cd, an arc segment de, an arc segment ea, an arc segment aafrom front to rear along a counterclockwise direction, wherein centers of the arc segment cd and the arc segment de are respectively located on both sides of the tooth profile.

The present disclosure is related to a slide valve, a slide valve adjustment mechanism and a screw compressor. The slide valve includes a static slide valve and a moving slide valve, wherein the static slide valve is fixedly installed in a slide valve cavity and provided with an axially-penetrating valve hole; a plurality of bypass holes communicating with the valve hole () are formed in the sidewall of the static slide valve, and an exhaust port is formed in the sidewall of one end of the static slide valve. The slide valve may avoid scraping between the slide valve and a screw rotor and the slide valve cavity. Gaps between the slide valve and parts which cooperate with same are reduced, so that the leakage is reduced while the energy efficiency of the compressor is increased.

The invention provides an air conditioner control method and device and an air conditioner. The air conditioner control device acquires a current temperature of a chilled water of a unit at a preset period; determine a target load of the unit, a target temperature of a chilled water and a target temperature of a cooling water based on a temperature of the chilled water set by a user and the current temperature of the chilled water; determine an evaporating parameter and a condensing parameter of the unit based on the target load of the unit, the target temperature of the chilled water and the target temperature of the cooling water; and determine operation parameters of a compressor based on the target load of the unit, the evaporation parameter and the condensation parameter. Therefore, the unit can operate based on the operation parameters.
