Vapor-compression refrigeration - Wikipedia

Vapor-compression refrigeration - Wikipedia

Vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Figure 1 depicts a typical, single-stage vapor-compression system. All such systems have four components: a compressor, a condenser, a thermal expansion valve (also called a throttle valve or metering device), and an .

UNDERSTANDING CIRCULATORS AND ISOLATORS

UNDERSTANDING CIRCULATORS AND ISOLATORS

Conduction, convection or liquid cooling can increase the average power rating of a circulator or isolator. The connector type is also important when the average power is significant. Captured SMA and hermetic seal connectors are limited in power rating because of their internal losses.

Cooling Chiller

Cooling Chiller

Home / Temperature Control Equipment / Cooling Chiller A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water).
