Abstract

This arrangement integrates the requirements for high-density data-processing system air cooling and data processing room air conditioning into one cooling concept. In this concept, a set of air conditioning units is connected directly to the data-processing system through ducts or pressurized space, as shown in the figure. In this integrated design, all the air moving devices are located within the air conditioning units. Accordingly, the need for blowers within the physical confines of the data-processing system is eliminated. It follows that the air conditioning units can be placed in a utility or anteroom. Also, the system may be directly connected into an existing or planned customer air conditioning system, and only one auxiliary air conditioning unit is needed as a standby.

Air Cooling for Data Processing Systems

This arrangement integrates the requirements for high-density data- processing system air cooling and data processing room air conditioning into one cooling concept. In this concept, a set of air conditioning units is connected directly to the data-processing system through ducts or pressurized space, as shown in the figure. In this integrated design, all the air moving devices are located within the air conditioning units. Accordingly, the need for blowers within the physical confines of the data-processing system is eliminated. It follows that the air conditioning units can be placed in a utility or anteroom. Also, the system may be directly connected into an existing or planned customer air conditioning system, and only one auxiliary air conditioning unit is needed as a standby.

The air conditioning unit can be designed to include slow-speed, high- volume, high-pressure air moving devices. The acoustical noise levels generated from these devices would be at lower tone frequencies, than those of the conventional high-speed blowers installed within processing systems. Should the proposed air conditioning units produce predominate noise levels, their acoustical treatment could be more easily implemented than in the space limited conventional concepts.

The trend in air cooling of high-density data-processing systema. is to provide more air at higher pressure per unit of component volume. Hence, larger size air moving devices...
