Temperature control assembly, control method and fan coil

Abstract

The invention discloses a temperature control assembly, a control method and a fan coil, and relates to the technical field of air conditioners. The technical problem that in the prior art, the installation position and the installation distance of a DDC electric control box are limited, and the control area of a single temperature controller is limited, so that the temperature distribution in thesame space is not uniform is solved. The temperature control assembly comprises at least two temperature controllers, wherein the at least two temperature controllers are connected in parallel, the at least two temperature controllers are installed on different control units respectively, so that the temperature of the control units where the at least two temperature controllers are located is detected and controlled through the at least two temperature controllers respectively. Compared with the DDC electric control box in the prior art, the temperature control assembly has the advantages that the distance between the temperature control assembly and a unit can be increased, so that the installation position and the installation distance of the temperature control assembly are not limited, moreover, the production cost can be reduced, and the competitiveness of a finished product is improved; and compared with the single temperature controller in the prior art, the control area of the temperature controller can be increased, so that the temperature of the same space reaches the preset temperature, and the temperature distribution is uniform.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and in particular to a temperature control assembly, a method for controlling the temperature control assembly, and a fan coil unit including the temperature control assembly. Background technique [0002] At present, cabinet-type fan coil units on the market are generally controlled by a DDC electric control box or a single ordinary temperature controller. DDC electric control box and single ordinary thermostat control have their own advantages and disadvantages. [0003] The DDC electric control box includes electric control components, electrical component mounting boards, DDC controller phase sequence protectors, terminal blocks, indicator lights, push button switches, DDC modules (panels) and AC contacts, etc. Although the DDC electric control box has rich functional modules, its size is large and requires a certain installation space; on the other hand, the DDC electric control bo...
