In the air supply system of the clean room air purification project, fresh air and return air are mixed in the air conditioning unit (AHU) of the air conditioning room. After a series of filtration and hot and humid treatment, the fresh air is sent to the top of the clean room through the air supply pipe, and then filtered by the efficient filter on the top and sent to the clean room. The return air is pulled back to the air conditioning unit in the air conditioning room through the return air duct located at the bottom or top of the clean workshop. The return air is re-mixed with fresh air in the air conditioning unit for reciprocating treatment. This is the work flow of the air supply and return system in the clean room, and it is a common practice in the clean room industry.
From the point of view of operation economy and energy saving, this primary return air supply system is mostly used in electronic industry clean workshop with lower cleanliness level, smaller supply air exchange times, smaller total supply air volume, larger indoor heat generation and larger temperature difference of supply air. That is to say, the air supply volume of air conditioning with eliminating waste heat and residual humidity is similar to or similar to that of purified supply air volume. Similarly, it is reasonable and feasible that no reheating or less reheating system is needed. If the air supply volume is large, the indoor heat production is small, and the air supply temperature difference is small, the re-heat required is large, and the operation economy is poor.
This kind of clean air supply and return is mostly used in the air supply system of industrial clean room with lower purification level ISO8 and ISO9 and higher indoor calorific value, that is, the air supply system of air conditioning is the same or similar to that of purified air supply.
