Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] This specific embodiment firstly provides a fan coil unit, which is a four-pipe fan coil unit with two-pipe mode and four-pipe mode. When the fan coil works in the two-pipe mode, its first temperature sensing package There is a first temperature at the interface, wherein the first temperature is greater than the preset temperature, preferably, the preset temperature is 100°C, and when the fan coil unit works in the four-pipe mode, the interface of the first temperature sensing package has a second temperature .

[0031] It is realized by the following method: when working in the four-control mode, input the four-control work command to the fan coil unit, and connect the temperature sens...

Abstract

The invention discloses a fan coil, a control method of the fan coil and a control device of the fan coil. The fan coil is a four-control fan coil, and a first temperature sensing packing port of the fan coil is provided with first temperature when a two-control job order is imputed in the fan coil. The first temperature is higher than preset temperature. The control method of the fan coil includes the steps of detecting temperature of the port after the fan coil is powered on, judging whether the temperature meets a preset condition or not, controlling the fan coil according to a first preset control mode when the temperature of the port meets the preset condition so that the fan coil works in a two-control mode, otherwise controlling the fan coil according to a second preset control mode so that the fan coil works in a four-control mode. The fan coil can be freely switched between the two-control mode and the four-control mode, and correct control policy can be adopted by the fan coil under the two working modes.

Description

technical field [0001] The invention relates to the field of fan coil units, in particular to a fan coil unit and its control method and control device. Background technique [0002] Fan coil unit is an ideal terminal product of air conditioners, widely used in hotels, office buildings, hospitals, commercial and residential, and scientific research institutions. The fan cools or heats the indoor air or the indoor and outdoor mixed air through the surface cooler and then sends it into the room to lower or increase the indoor temperature to meet people's comfort requirements. [0003] The fan coil has two pipes and four pipes. The four pipe fan coil includes both cold water coils and hot water coils. Each set of coils has one inlet and one return, and two sets of water pipes are respectively connected to cold water and hot water, cooling and heating. It can be switched at any time, so that the terminal equipment can freely choose the operation mode of heating or cooling at an...
