technical field

The invention relates to the technical field of environmental temperature control, in particular to a temperature control system with a movable air outlet based on the Internet of Things.

Background technique

In the prior art, temperature control systems using air-conditioning for refrigeration or heating are mainly divided into independent air-conditioning temperature controllers and central air-conditioning temperature control systems. Most of the existing independent air-conditioning temperature controllers use split units, which are composed of an outdoor condenser and an indoor evaporator, and controllers are installed in the condenser and the indoor evaporator respectively, and the controller is used to control the outdoor compressor. It can control the working status of indoor fans, such as controlling cooling, heating, temperature, dehumidification, ventilation, wind direction, wind speed and other working modes. Indoor units of air conditioners generally include cabinet units and wall-mounted units. However, no matter it is a cabinet type machine or a wall-mounted machine, the installation positions of the air exhaust port and the air return port are fixed, that is to say, once the air conditioner is installed and fixed, the positions of the air exhaust port and the air return port are already fixed It is fixed in one position and cannot be adjusted and changed. If you need to change the positions of the air outlet and return air outlet, you need a professional to move the machine. Even the central air conditioner cannot be changed arbitrarily once the positions of its exhaust and return air outlets are installed. However, people have a large movable space indoors.

The person stays in another location. In this way, different locations in the room have different requirements for temperature, or different people who are in the same room have different requirements for indoor temperature. Especially in large public places, such as shopping malls, entertainment venues, exhibition halls and other public places, if the temperature is adjusted lower so that the temperature of the temperature-regulated space reaches the comfortable temperature that people want to achieve, if it is necessary to make people more comfortable When the temperature of densely populated places reaches the comfortable temperature that people want to achieve, the output power of the air conditioning system required for cooling or heating is relatively large. When the temperature is high, the output power of the air conditioning system required for cooling or heating is relatively small. How to make the indoor occupants feel comfortable, minimize the output power of the air conditioning system, and enable people with different temperature requirements in the same space to achieve a satisfactory and comfortable temperature sense, and at the same time achieve energy saving Efficacy has become a technical problem to be solved by those skilled in the art.
