Description

Central air-conditioning multi-supply fan indoor temperature control centralized control device

The utility model relates to a central air-conditioning temperature control device, in particular to a central air-conditioning multi-supply fan which can centrally control multiple blowers to set the same or different temperature values to meet the different temperature requirements of different indoor areas under dynamic or static conditions. Indoor temperature control centralized control device.

In the past, the air-conditioning device of the central air-conditioning system is to reduce the indoor temperature of the closed space in the state of air supply or cold air output. However, in a large space, due to the difficulty of air circulation, it is difficult for the air to diffuse to every corner, and in addition, each area in the space Factors such as heating elements (such as personnel activities or electrical appliances, etc.) and the external environment (such as outdoor sunlight, etc.) will cause the deterioration of the indoor air conditioning quality. As far as the central air-conditioning devices currently on the market are concerned, in a large space, one operation controller is used to simultaneously control multiple sets of temperature controllers and multiple blower units corresponding to them, so that the blower sets can perform air supply at the same speed, so as to Spread the cold air to every corner of the room, but this method only provides the same air volume output of each blower unit, and cannot achieve the temperature control effect of the entire space. For example, when a single operation controller controls multiple sets of blower units at the same time When the strong wind section outputs cold air, the number of heating elements in some areas in the large space may be less than that in other areas, so that the temperature in this area is lower and there is a situation of overcooling. When the cold air is output in the weak wind section, in another part of the same large space, the temperature in this area may drop very slowly due to the large number of heating elements and the influence of external environmental factors such as outdoor sunlight. However, it is not cool enough. Therefore, it is difficult to maintain suitable room temperature in different areas of the same indoor space by using a single operation controller to simultaneously control multiple air supply units to deliver the same wind speed of cold air. Therefore, there is another way to solve the problem of uneven temperature control in a large space with multiple sets of operation controllers and the same number of blowers through one-to-one control. However, this method not only makes the cost too high, but also the construction is cumbersome. It is inconvenient to operate and set one by one during operation.
