Air conditioning companion stabilizer system


An air conditioning companion stabilizer system for improving the operating cooling efficiency of refrigeration cycle components in air conditioning systems integrates the refrigeration cycle components with two independent, closed loops whose operation is complementary of one another. A temperature stabilizing loop functions in ambient conditions that lower cooling efficiency and is operative to absorb heat from the refrigerant exiting the condenser, thereby lowering the temperature of the refrigerant before it arrives at the expansion valve.

Computer room air conditioning unit


An enclosed air conditioning unit includes a filter section and a cooling section through which intake air passes before being discharged into a space within a building. The orientation of the filter section and cooling section is substantially vertical, and the airflow path through the filter section and the cooling section is substantially horizontal, resulting in reduced face velocities across these components, thereby increasing filtration efficiency and cooling effectiveness, while allowing the physical size and configuration of the air conditioning unit's enclosure to be the same as or smaller than the enclosures for conventional air conditioning units having comparable or lower performance..

Structure of variable swash plate type compressor


A structure of a variable swash plate compressor includes: a rotatable shaft having a flow path through which a refrigerant flows; a rotor fixed and coupled to the shaft and has a rotor arm formed at one side of the rotor; a swash plate connected to the rotor arm by a hinge pin and mounted on the shaft so that an inclination angle is variable with respect to the shaft; a compressive coil spring installed on the shaft between the swash plate and the rotor; a lift slidably coupled to the shaft and connected to the swash plate; and a fixing device formed in the shaft and fixes the lift so as to maintain the inclination angle of the swash plate, thereby basically preventing an operational delay of the compressor, securing performance at the time of initially operating an air conditioning device, and improving marketability.. .
