Central air conditioner tail end energy-saving control method

Abstract

The invention discloses a central air conditioner tail end energy-saving control method. A timer is in serial-in connected to a power supply main circuit of a fan coil, and a power-off time and a power-on time are set according to the working time of a user, therefore, the power of the fan coil is cut off automatically in a nonworking time, and energy is saved effectively. A device is composed of a distribution box and the timer, a breaker and the timer are mounted inside the distribution box, one end of the timer is connected with the breaker, and the other end of the timer is connected with a temperature control plate. According to the central air conditioner tail end energy-saving control method provided by the invention, under a premise of fully meeting the users' using requirements, power consumption of the fan coil and cold and heat source consumption are reduced, moreover, compared with a scheme that a human body detector is mounted, the central air conditioner tail end energy-saving control method is simpler, more reliable and more effective, and is lower in cost. Under the premise of meeting the normal use of a central air conditioner, the control of automatically closing the fan coil is achieved, and energy can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an energy-saving control method for a central air-conditioning terminal. Background technique [0002] The fan coil unit is an ideal terminal product of the central air conditioner. Its working principle is to continuously recirculate the air in the room where the unit is located, so that the air is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant. The switch and control of the fan coil unit are realized by the temperature control panel. [0003] The function of the temperature control panel is mainly to detect the real-time temperature of the room in time through high-precision temperature-sensing devices, and compare it with the set temperature value to control the cooling / heating valve of the fan coil unit and the opening and closing of the fan, so that the room temperature is kept constant at A comfortable t...

Problems solved by technology

[0004] Because the temperature control panel needs to collect the ambient temperature of the area where the fan coil unit is located, it is impossible to install it at the entrance and exit like a light switch, and it must be scattered in different corners, so users may forget to turn off the temperature control when they leave Panels, or a few of them are missed, resulting in unnecessary waste, which is also an important reason for the high energy consumption of air conditioners
