Problems solved by technology

[0017] Among the liquid refrigerant and gaseous refrigerant flowing into the storage tank 4, the gaseous refrigerant is sucked by the compressor, while the liquid refrigerant is stored inside the storage tank 4. If it is a high-power central air-conditioning single-pipe system with a large difference in cooling load, the storage tank 4 The liquid refrigerant inside will flow into the compressor, causing the loss of the compressor and the inability to run the air conditioner

Embodiment Construction

[0054] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0055] Such as figure 2 , image 3 As shown, the central air conditioner of the present invention has a structure that utilizes two distributors to control 6 rooms. The central air conditioner of the present invention is composed of an outdoor unit 100 , a distributor 200 and an indoor unit 300 . The distributor 200 is connected with the outdoor unit 100 and is composed of a plurality of (for example, two) first and second distributors 201 and 202 . The indoor unit unit is composed of first to sixth indoor units 301, 302, 303, 304, 305, 306 installed in each room.

[0056]The outdoor unit 100 and the first and second distributors 201 and 202 are connected to the main pipe P1 of the outdoor unit 100 . The first distributor 201 and the first to third indoor units 301, 302, and 303 are connected by first, second, and third pipes P2, P3, and P4...

Abstract

The invention discloses a center air conditioner and control method, which consists of indoor set and outdoor set, wherein the outdoor set contains several first compressors, second compressors, storage tank, condensation part, evaporation part, temperature perception part, outdoor set control part on the storage tank to evaporate the coolant into gas; the evaporation part connects outlet tube side of first and second compressor; the temperature perception part detects the temperature of inner storage tank; the outdoor set control part controls the heat source to storage tank selectively according to the perception temperature of outdoor control part. The invention prevents the liquid coolant flowing into the compressor and reduces the loss power of compressor and probability for stopping system operation, which improves the satisfaction degree for users.

Description

technical field [0001] The invention relates to an air conditioner, especially a central air conditioner capable of preventing liquid refrigerant from flowing into a compressor and a control method thereof. Background technique [0002] An air conditioner is a home appliance that maintains the air in the room in an appropriate state according to the use and purpose. For example, keep the indoor temperature at a cool temperature in summer. In winter, keep the indoor temperature at a warm state, adjust the indoor humidity, and adjust the indoor air to a suitable clean state. [0003] As air conditioners and other products used in daily life are gradually becoming popular, consumers have higher requirements for performance and usability. [0004] Air conditioners can be divided into split air conditioners, integrated air conditioners, wall-mounted air conditioners, cabinet air conditioners, family air conditioners, large air conditioners, and central air conditioners. The sp...
