[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The purpose of the utility model is to provide a dry and wet working condition speed control system, which can ensure the use effect under different operating conditions.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] like Figure 1 As shown, the utility model provides a dry and wet working condition speed control system, comprising: a fan coil unit and a controller 3 connected to the fan coil unit, and the controller 3 is wirelessly connected to the terminal through a communication module.

[0022] Among them, the terminal is used to output a mode control signal; the communication module is used to transmit the mode control signal; the controller 3 carries setting parameters for the dry working mode and the wet working mode, and is used to trigger the corresponding mode parameters according to the mode control signal to control the fan coil unit to heat or cool; the setting parameters of the dry working mode include the motor 1 speed that meets the set air volume and the set heating capacity requirements; the setting parameters of the wet working mode include the motor 1 speed that meets the set circulation air volume and the set cooling capacity requirements.

[0023] As a specific embodiment, the fan coil unit includes: a motor 1 and a surface cooler 2; the motor 1 is connected to a controller 3 for controlling the speed in a corresponding mode; the surface cooler 2 is connected to a water inlet pipe and a water outlet pipe, respectively, and the cooling / heating medium water in the water inlet pipe and the water outlet pipe is centrally supplied from the machine room. The motor 1 is a brushless DC motor 1.

[0024] In a further design, the surface cooler 2 includes a housing and a coil disposed within the housing; the housing is further fixedly connected to a motor 1. The housing is further provided with an air inlet and an air outlet, and the coil is composed of a plurality of fins 4; each fin 4 is arranged in parallel.

[0025] Based on the above technical solution, an embodiment is provided.

[0026] Since the air volume of fan coil units varies significantly when operating under dry conditions and wet conditions, to improve the effect of reduced air volume under wet conditions, the motor 1 speed control mode is divided into cooling mode control and non-cooling mode control. Through experiments, the required motor 1 speeds under normal dry conditions and normal wet conditions are determined, and the relevant parameters are set in different control modes. For example, in heating mode, the motor 1 speed measured under dry conditions is used; while in cooling mode, the motor 1 speed measured under wet conditions is used, thus ensuring the performance under different operating conditions.

[0027] The fan coil unit cools or heats the indoor air or mixed air from outside through the surface cooler 2 and then delivers it to the room, lowering or raising the indoor temperature to meet people's comfort requirements. The cold (hot) water in the coil is centrally supplied from the machine room.

[0028] In specific applications, the air volume and heating capacity of the corresponding model are met in the heating mode, and the circulating air volume and cooling capacity of the corresponding model are met in the cooling mode.

[0029] However, in cooling mode, the hot air absorbed by the fan passes through the cold surface cooler 2. Due to natural phenomena, condensation will form between the fins 4 of the surface cooler 2, which will create resistance to air circulation and reduce air volume. Therefore, in cooling mode, the output of motor 1 is increased to increase the air output to compensate for the loss of air volume.

[0030] Therefore, this embodiment has the following beneficial effects:

[0031] The dry and wet working condition speed control system provided by the present invention achieves efficient and precise adjustment of the fan coil unit in different operating modes by finely distinguishing and optimizing the motor 1 speed control strategy under dry and wet working conditions, bringing significant beneficial effects.

[0032] First, by introducing an intelligent controller 3 and wireless communication module, the system enables remote mode control and real-time monitoring of fan coil units, greatly enhancing the system's flexibility and convenience. Users can adjust operating modes at any time through the terminal based on actual needs, eliminating the need for on-site operation and improving efficiency.

[0033] Secondly, to address the significant differences in air volume requirements between dry and wet operating conditions, the system has specifically designed different speed parameters for Motor 1 to ensure optimal heating or cooling performance in each condition. In heating mode, the system uses the optimized speed for dry conditions to ensure adequate air volume and heating capacity. In cooling mode, based on the characteristics of wet conditions, Motor 1 speed is increased to compensate for air volume loss caused by condensation, effectively maintaining indoor comfort and air circulation.

[0034] Furthermore, the use of a brushless DC motor (1) as the power source not only improves the fan coil unit's operating efficiency, but also reduces energy consumption and noise, extending the unit's service life. Furthermore, the coils within the surface cooler (2) utilize a multi-fin, parallel arrangement (4), increasing the heat exchange area and efficiency, further enhancing the unit's cooling or heating capabilities.

[0035] To sum up, the dry and wet working condition speed control system provided by the utility model effectively solves the problems of low operating efficiency and poor comfort of traditional fan coil units under different working conditions through intelligent and refined speed control strategies, and achieves efficient, energy-saving and comfortable air-conditioning adjustment effects, with significant technological progress and practical application value.
