Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0028] In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, 'module', 'part' or 'unit' may be used in combination.

[0029] The mechanical outdoor unit rotation method in the prior art does not take into account the different capacities of the outdoor units and the energy efficiency of the whole unit after outdoor units with different capacities are combined together. Based on this, the present invention proposes a combination and rotation operation scheme of outdoor units, which forms a high-energy-efficienc...

Abstract

The invention discloses a combined alternation operation method and device of outdoor units and a VRV system. The method comprises the following steps that 1, a plurality of combination modes of the outdoor units are determined according to the current power-on indoor unit capacity; 2, priority ranking is carried out on the plurality of combination modes according to a preset rule; and 3, the outdoor units are operated in an alternating mode according to the ranked combination modes. According to the method, efficient combination modes of the outdoor units are determined according to the current power-on indoor unit capacity and the capacity of each outdoor unit, the efficient alternation operation scheme is determined through priority ranking, and therefore the energy efficiency of the system during partial-load operation can be improved, the purpose that the optimal refrigerating and heating effects are achieved while the operation cost is saved is achieved, and the effective servicelife of the units is prolonged.

Description

technical field [0001] The present invention relates to the field of unit technology, in particular to a method and device for combined and alternate operation of outdoor units and a multi-connection system. Background technique [0002] Usually, in order to increase the effective operating life of the multi-connected system and avoid excessive operation and loss of individual outdoor units, each manufacturer's multi-connected units are designed with a module rotation scheme to switch the startup sequence of each outdoor unit during operation. For example, the startup sequence in the last cycle is outdoor unit 1 / outdoor unit 2 / outdoor unit 3, and in the next cycle it is outdoor unit 2 / outdoor unit 3 / outdoor unit module 1, and so on. [0003] As we all know, when multi-connected outdoor units of different capacities are combined together, and the operating energy efficiency of the whole unit is different under different combinations when operating at partial load, this kind o...
