Problems solved by technology

[0004] As mentioned above, during the heating process, the multi-split unit controls the start and stop of the compressor to maintain the indoor temperature within a certain range. The temperature of the pipeline of the unit is also low, so the fan of the indoor unit cannot be turned on immediately, and the time

Embodiment Construction

[0033] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] see figure 1 , figure 1 It is a schematic composition diagram of the multi-connected air-conditioning system of the present invention. The multi-connected air-conditioning system includes several outdoor units 1 and indoor units 2. In this embodiment, a multi-connected air-conditioning system with one outdoor unit 1 and one indoor unit 2 is used as an example for illustration below, for those skilled in the art In other words, with reference to the following description, it is easy to apply the controller control principle of the present invention on the multi-connected air-conditioning system and its quick-start heating method to a system with more than one outdoor unit 1 and one indoor unit 2 (for example, Two outdoor units and three indoor units) multi-connected air conditioning system, which will not be ...

Abstract

The invention discloses a multi-split air conditioner system. When the temperature of an indoor environment reaches the preset temperature, the multi-split air conditioner system is controlled through a controller of the multi-split air conditioner system to run in a standby-ready mode, a refrigerant circulates between a compressor and an air and liquid separator, the capacity output of the compressor is controlled, and the pressure of a refrigerant outlet of the compressor is maintained within certain range, so when the multi-split air conditioner system is restarted to generate heat, the phenomenon of raising the lower pressure of the refrigerant to the working pressure is avoided, the cold air prevention time of an indoor unit is shortened, and the better user experience can be obtained. In addition, by setting the time of the multi-split air conditioner system entering the standby-ready mode through the controller, when the time of entering the standby-ready mode reaches the preset value, the multi-split air conditioner system is controlled to enter the standby mode, and the compressor is closed, so as to save the electric energy. The invention also provides a quick-starting heat generation method suitable for the multi-split air conditioner system.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a multi-connected air conditioning system and a quick-start heating method thereof. Background technique [0002] The multi-unit air-conditioning system is referred to as multi-unit, which is a new type of air-conditioning system with the characteristics of a centralized air-conditioning system. It integrates frequency conversion, variable capacity and other technologies, and has the advantages of energy saving, comfort and flexible control. And layout can meet the requirements of buildings of different scales. [0003] The application of multi-split units in people's living and working environments is becoming more and more popular, so people have higher and higher requirements for the comfort of air-conditioning systems. During the heating process of the multi-split air conditioner system, when the room temperature detected by the indoor unit is higher than the set te...
