Description
Technical Field
The invention relates to the technical field of fresh air handling units, in particular to a suspended ceiling fresh air handling unit system preventing freezing in winter.
Background
A fresh air handling unit is an air conditioning device that provides fresh air. The operating principle is that fresh air is extracted outdoors and is sent indoors through a fan after being treated by dedusting, dehumidifying (or humidifying), cooling (or heating) and the like, and the original air in the room is replaced when entering the indoor space, and the method specifically comprises the following steps: the temperature control system of the fresh air handling unit consists of a proportional-integral temperature controller, a temperature sensor and an electric regulating valve which are arranged in an air supply pipe. The controller is used for transmitting the air supply temperature detected by the temperature sensor arranged in the air supply duct to the temperature controller for comparison with the temperature set by the controller, and the temperature controller gives a signal of opening/closing a valve to the electric regulating valve according to the result of PI operation, so that the air supply temperature is kept in a required range; the electric regulating valve is interlocked with the fan to ensure that the air valve is closed simultaneously when the power supply of the fan is cut off. The electric regulating valve can also realize linkage with the fan, and the electric regulating valve is closed when the fan cuts off the power supply; when the temperature measured by the sensor reaches or is lower than the set temperature, the temperature controller gives a valve closing signal to the electric valve, and the valve closing point of the electric valve is connected with the valve closing of the through valve. If the measured temperature does not reach the set temperature, the temperature controller gives a valve opening signal to the electric valve, and the opening contact of the electric valve is communicated with the valve to open. When the temperature measured by the sensor reaches or is higher than the set temperature, the temperature controller gives a valve closing signal to the electric valve, the valve closing contact of the electric valve is connected, and the valve is closed. If the measured temperature does not reach the set temperature, the temperature controller gives an opening signal to the electric valve, the opening contact of the electric valve is connected, and the valve is opened; when the filter screen is blocked or exceeds a specified value, the pressure difference switch gives a switching signal; when the temperature of the coil is too low, the low-temperature anti-freezing switch gives a switching signal, and the fan stops running to prevent the coil from freezing and cracking; but in the cold in china north, the sand blown by the wind area, furred ceiling new trend unit heating coil still often is by the frost crack, its leading cause is that the interior fluid of heating coil receives cold wind to influence, volume expansion when the fluid solidifies in the heating coil, finally lead to the heater coil by the spalling, this normal operating that has not only influenced new trend unit, and increased the maintenance of equipment and user's operation administrative cost, also influenced furred ceiling new trend system in the popularization and application in cold areas of china to a certain extent, furred ceiling new trend unit operation condition in winter in the past is: outdoor fresh air is directly sent into a room through a fresh air handling unit without effective control, the probability of frost cracking of a heater pipeline of the fresh air handling unit is high due to large indoor and outdoor temperature difference, or an electric heating anti-freezing method is adopted, but when an electric heater is damaged in practical application, the accident of frost cracking of the heater pipeline of the fresh air handling unit still occurs, so that the anti-freezing fresh air handling unit needs to be designed urgently, and based on the anti-freezing fresh air handling unit, the suspended ceiling fresh air handling unit system which is anti-freezing in winter is designed to solve the problems.
