Embodiment 1

[0044] In this embodiment, the adjustment device of the fan coil unit is described as follows.

[0045] The adjusting device of the fan coil unit of this embodiment includes a detection module 1, a calculation module 2, a judgment module 3 and an adjustment module 4, such as figure 1 shown. continue to see figure 1 , the detection module 1 is connected to the calculation module 2, and the detection module 1 is used to detect the real-time temperature of the air-conditioned room and send the detected real-time temperature to the calculation module 2. The computing module 2 is connected to the judging module 3 , and the computing module 2 is used to compare the real-time temperature with the set temperature and send the comparison result to the judging module 3 . The judging module 3 is connected to the regulating module 4, and the judging module 3 judges whether the regulating module 4 operates based on the comparison result of the computing module 2. The adjustment module 4...

Embodiment 2

[0060] In this embodiment, the fan coil unit is described as follows.

[0061] The fan coil unit in this embodiment includes the adjustment device for the fan coil unit described in any technical solution in Embodiment 1. The fan coil unit in this embodiment has an adjustment device, and through the adjustment device, self-detection and self-regulation can be realized. Specifically, it can automatically realize the adjustment of the fan coil flow path and water flow according to the real-time indoor temperature and the change of the set temperature, so as to achieve the purpose of constant indoor temperature, thereby improving the comfort of the fan coil unit.

[0062] The fan coil unit of this embodiment solves the problem that the heat exchange area cannot be adjusted when the model of the existing fan coil unit is fixed; The problem of short life; it can effectively reduce the energy consumption of the fan coil air-conditioning system, especially the energy consumption of ...

Embodiment 3

[0068] In this embodiment, the adjustment method of the fan coil unit is described as follows.

[0069] The adjustment method of the fan coil unit in this embodiment is realized by using the adjustment device for the fan coil unit described in any one of the technical solutions in the first embodiment.

[0070] image 3 A temperature control circuit diagram of a preferred embodiment of the regulating device of the fan coil unit is shown. Such as image 3As shown, the regulating device of the fan coil unit is based on the detected real-time temperature of the air-conditioned room and the set temperature of the air-conditioned room, and uses the flow regulating device 10, the rubber ball plug 11 and the spring 12 to adjust the water flow of the fan coil unit to realize automatic distribution. Flow and number of branches.

[0071] According to a preferred embodiment, the adjustment process of the fan coil unit is as follows:

[0072] Suppose the real-time temperature of the a...

Abstract

The invention discloses an adjusting device of a fan coil, the fan coil and an adjusting method thereof, and relates to the technical field of air conditioning equipment. The problem that a fan of a fan coil and a water valve in the prior art need to be frequently started and stopped and the indoor temperature fluctuation range of an air conditioner room is large are solved. The adjusting device comprises a detection module, a calculation module, a judgment module and an adjustment module, wherein the detection module is used for detecting the real-time temperature of the air conditioner roomand sending the real-time temperature to the calculation module; the calculation module is used for comparing the real-time temperature with a set temperature and sending a comparison result to the judgment module; the judgment module judges whether the adjustment module is operated or not on the basis of the comparison result; and the adjustment module adjusts the refrigerating capacity and / or heating capacity of the fan coil on the basis of an instruction of the judgment module. The adjusting device adjusts the flow of the fan coil and / or the flow path of the fan coil to adjust the refrigerating capacity and / or heating capacity of the fan coil, so that the indoor temperature is kept constant, and the use comfort of a fan coil air conditioning system is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to an adjusting device for a fan coil, a fan coil and an adjusting method thereof. Background technique [0002] With the improvement of people's living standards, central air-conditioning systems are more and more widely used, especially fan coil units. As a widely used central air-conditioning terminal equipment, fan coil unit is often used to control indoor temperature and humidity and improve the comfort of indoor personnel. [0003] However, in the fan coil unit in the prior art, once the heat exchange area is determined, it cannot be adjusted. It can only be changed by changing the fan speed (that is, changing the air volume), passively changing the water flow of the system, and changing the size of the fan coil unit. The cooling or heating capacity of the fan coil unit, and then adjust the indoor temperature and humidity. [0004] However, the change of a...
