In the clean room, the temperature in the clean room is higher due to unstable heat dissipation equipment in the clean room, or the temperature in the clean room is lower due to the problem of a front-end centralized air conditioning treatment system, so that the temperature requirement of clean room production on the indoor environment cannot be met.
The traditional fan filtering air supply device is only used as the air supply end of the clean room air conditioning system, has only a filtering air supply function and has no temperature control function.
For example, chinese patent CN217178796U discloses a positive pressure air supply device for clean room, which is characterized in that a positive pressure air supply mechanism is arranged in the channel to realize positive pressure air supply for clean room, and a check valve effectively prevents air backflow, and ensures the cleanliness and positive pressure state in clean room, but does not explain the regulation and control of temperature.
Disclosure of Invention
In view of the foregoing, an object of the present utility model is to provide a temperature-controlled filtering and air-blowing device for a clean room.
The specific technical scheme is as follows:
the utility model provides a clean room is with control by temperature change filtration air supply arrangement, includes the box, and supply-air outlet and air intake have been seted up respectively at the both ends of box, are equipped with fin formula heat exchanger in the box, are equipped with the trip valve on fin formula heat exchanger's the pipeline and are used for controlling the two-way governing valve of discharge size, still are equipped with the fan in the box, be used for monitoring the temperature sensor of box and be used for regulating and controlling the electronic blast gate of flowing through fin formula heat exchanger department amount of wind size, fan, temperature sensor and electronic blast gate are connected to the controller respectively.
Further, the fin type heat exchanger is arranged on one side in the box body, the electric air valve is arranged on the other side of the box body, and the air quantity flowing through the fin type heat exchanger is regulated and controlled by controlling the opening degree of the electric air valve.
Further, a filter is arranged at the air supply opening for filtering the air sent into the clean room.
Further, the temperature sensor is located at the air inlet and can detect the temperature of the entering air, so that the air quantity and the water quantity flowing through the fin type heat exchanger can be regulated and controlled respectively through the electric air valve and the two-way regulating valve according to actual requirements, and the combined regulation of the air temperature is realized.
Further, the electric air valve and the fin type heat exchanger are positioned on the same plane.
Further, the distance between the fin type heat exchanger and the electric air valve is 10-50mm.
The basic principle is as follows:
the fin type heat exchanger is connected with low-temperature water or hot water, and the temperature reduction and the temperature increase of the air in the box body are controlled through the heat exchange between the air and the fin type heat exchanger.
In the initial state, the opening of the electric air valve is set to be 100%, the air quantity flowing through the fin type heat exchanger is minimum at the moment, the air duct resistance is minimum, the opening of the two-way regulating valve is regulated and controlled through a temperature set value on the temperature sensor, the flow of low-temperature water or hot water in the fin type heat exchanger is regulated and controlled, and the air temperature is controlled.
When the opening degree of the two-way regulating valve is 100%, and the air temperature can not meet the requirement, the air quantity flowing through the fin type heat exchanger is increased by reducing the opening degree of the electric air valve, so that the air temperature in the box body is further controlled.
The utility model has the beneficial effects that:
the fin type heat exchanger convects with the inner air and conducts heat in a radiation way, and the control of the two-way regulating valve is used for controlling the flow of cold water and hot water in the fin type heat exchanger and controlling the temperature of the air in the clean room;
the opening degree of the electric air valve is controlled, so that the air quantity flowing through the fin type heat exchanger is controlled, and the air temperature in the clean room is further controlled.
