Water-flow-variable air conditioner tail end and work method thereof

Abstract

The invention relates to a water-flow-variable air conditioner tail end. A water way adjusting electromagnetic valve and a water inlet temperature sensor are arranged in front of a coil heat exchanger, and a water outlet temperature sensor is arranged after the coil heat exchanger. The front side and the rear side of the coil heat exchanger pass through a pressure difference sensor. An air return opening of the air conditioner tail end is provided with an air return temperature sensor and an air return humidity sensor. An air outlet of the air conditioner tail end is provided with an air outlet temperature sensor and an electric heating device. The water way adjusting electromagnetic valve, the water inlet temperature sensor, the water outlet temperature sensor, the pressure difference sensor, the air return temperature sensor, the air return humidity sensor, the air outlet temperature sensor and the electric heating device are in signal connection with a control center. The control center receives real-time monitoring data of the water inlet temperature sensor, the water outlet temperature sensor, the pressure difference sensor, the air return temperature sensor, the air return humidity sensor and the air outlet temperature sensor and is used for controlling the opening degree of the water way adjusting electromagnetic valve, running of the electric heating device and the rotating speed of a draught fan.

Description

technical field [0001] The invention relates to a variable water flow air conditioner terminal and a working method thereof, belonging to the technical field of refrigeration equipment. Background technique [0002] The existing air conditioner terminal generally only includes a water solenoid valve, coil heat exchanger, fan, and controller. The indoor return air is blown to the coil heat exchanger after being boosted by the fan, and the water solenoid valve is used to shut off the water flow. supply. There are fan control buttons on the controller to control the speed of the fan, such as high speed, medium speed, and low speed. At the same time, there are switch, cooling and heating setting buttons, as well as temperature setting knobs or buttons. The controller comes with a room Temperature Sensor. When cooling, when the room temperature is higher than the set value, the water solenoid valve is opened, otherwise it is closed; when heating, when the room temperature is lo...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a variable water flow air conditioner terminal and its working method. By setting inlet and outlet water temperature sensors at each parallel air conditioner terminal and setting a waterway regulating solenoid valve before each air conditioner terminal, the front and rear sides of the air conditioner terminal At the same time, the above-mentioned sensors, solenoid valves, fans and fresh air valves at the end of the air conditioner are all monitored by the control center, so as to obtain a more comfortable room temperature and humidity, and at the same time solve the problem of constant water flow at the end and water flow at the end. Issues such as lack of comfort and energy waste caused by unbalanced air volume and fan air volume cannot be automatically adjusted
