Control method for variable water temperature of fan coil

Abstract

The invention discloses a control method for variable water temperature of a fan coil, relates to the field of air conditioners, and aims to solve the problems that in temperature control, only the three-gear air speed of the coil fan and the opening and closing states of a water valve are controlled simply, automatic adjustment cannot be achieved according to the change of actual parameters and consequently the indoor temperature is unstable at the control target temperature. The method comprises the following steps of S1, counting the current geographical environment and the current temperature information according to the installation position of the fan coil; S2, acquiring the distance between a water source and the fan coil; S3, counting the environment temperature of the current geographic position according to big data; S4, increasing the water temperature of the fan coil according to the requirements; S5, installing a timer at the exterior of the fan coil, and meanwhile installing an alarm module on one side of the timer; S6, installing a plurality of detection sensors in the fan coil, and performing timing and periodic detection; S7, uploading the recorded data to a server for storage; and S8, monitoring data in the fan coil on line by using a mobile phone module.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method for controlling variable water temperature of a fan coil unit. Background technique [0002] The fan coil unit is referred to as fan coil unit. It is one of the terminal devices of the air conditioning system composed of small fans, motors and coils (air heat exchangers). When chilled water or hot water flows through the coil pipe, it exchanges heat with the air outside the pipe, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. It is a commonly used cooling and heating terminal device. The fan coil unit should create an indoor air environment suitable for human comfort. Since the indoor air environment plays a very important role in the comfort of the human body, creating the indoor air environment required for the comfort of the human body has become the primary task of the air conditioner. If the indoor air temperature...

Problems solved by technology

[0004] The purpose of the present invention is to provide a fan coil unit water temperature control method to solve the temperature control of the prior art proposed in the above background technology, which simply controls the third gear wind speed of the fan coil unit and the opening and closing state of the water valve, which cannot be based on actual conditions. The automatic adjustment of parameter changes may easily cause the problem that the indoor temperature is unstable at the control target temperature
