Attention Should Be Paid To The Installation Of Energy Recovery Ventilation System
The energy recovery ventilation system is one of the most energy saving and environmental protection fresh air systems, and is also the mainstream form of fresh air system. The energy recovery ventilation system is composed of a set of forced supply air system and a set of forced exhaust air system. The fresh air enters the room from the duct of the air supply system, and the exhaust air is discharged to the outdoor through the duct of the air exhaust system. The flow direction of the fresh air and exhaust air, and the layout of the fresh air inlet and exhaust air outlet can be actual and arranged according to specific requirements. Fresh air can be filtered, sterilized and preheated as required before entering the room, which is suitable for occasions with special requirements on fresh air quality.
One-way flow system is the system of "forced exhaust and natural inlet". Take the residence as an example: the air outlet is installed in the kitchen, bathroom and other places where the dirty air is concentrated. It is necessary to install a self-balancing air inlet above the windows of the bedroom and living room to keep the room fresh. Fresh air flows into the room after being treated by the self-balancing air inlet.
Bidirectional flow fresh air system is "forced exhaust, forced air supply" system, which consists of a group of forced air supply system and a group of forced exhaust system. The difference between air supply and one-way flow lies in that the form of air supply changes from natural wind to forced air supply. The fresh air enters the room from the pipe of the air supply system, and the exhaust air is discharged to the outdoor through the pipe of the air exhaust system. The flow direction of fresh air and exhaust air, the arrangement of fresh air inlet and exhaust air outlet can be practical and arranged according to specific requirements. Bidirectional flow can be divided into bidirectional flow heat recovery system and bidirectional flow non-thermal recovery system.
Attention should be paid to the installation of energy recovery ventilation system:
According to the experience of installation of new air system for many years, we remind the owner in the design of installation of new air system, the key to consider the layout of the pipeline, on the one hand to reduce the loss of air volume as far as possible, on the other hand to meet the requirements of the height of the owner's ceiling, and finally to cooperate with the central air-conditioning pipeline.
1. First of all, what kind of pipeline should be considered, and it is recommended to give priority to hard pipeline;
2. The owner shall consider the arrangement of pipelines and minimize the loss of air volume;
3. We need to meet the customer's requirements for ceiling height of interior overall design;
4. Whether the structural conditions for the positions requiring perforation through the wall are met or permitted shall not be at the cost of damaging the overall structure of the room;
5. Selection and processing of the location of air outlet and air return outlet of air conditioning.
