Abstract: The problem of controlling the temperature of the different units in a process tool system which have to be cooled or heated using thermal transfer fluid at selected setpoints and flow rates is resolved by a system having multiple modular units each with some operative and form factor commonality but at least dual functional capability.

By employing operative units which can be internally varied to provide different thermal capacities within form factor constraints, the system enables concurrent temperature control needs of a number of different units to be met with an energy efficient, low footprint, highly adaptable system.

Abstract: The present invention relates to a dual phase condenser system, including an air-cooled portion, a water-air-cooled portion and a fan. The air-cooled portion can be further divided into two sectors, wherein the external air, drawn by the fan, passing through the second sector of the air-cooled portion first then to the water-air-cooled portion. The ability of air absorbing water vapor can be increased significantly in the water-air-cooled portion due to the increase of vapor pressure deficit (VPD) of the air passing through the air-cooled portion of the condenser. The dual phase condenser system of this invention is a 3-stage air-cooled condenser when shortage of water occurred. By separating gaseous and liquid refrigerants, the ability of removing thermal energy of the refrigerants can be increased. This invention required no extra fans, thus the EER can be increased when compared with the traditional one stage or patented two-stage air-cooled condenser.
