This chapter presents a detailed description of the refrigeration compressor types (reciprocating, rotary screw, centrifugal and scroll compressors) and the heat pump (HP) types. Important information on the selection of the heat source and HP systems and domestic hot-water production for nearly zero...
A different form of geothermal pump is one that uses a body of water, such as a lake or large pond, as the source of heat. A closed and sealed system of refrigerant-filled piping is looped at least 8 feet below the surface of a suitable body of water, and this lake or pond provide...
Lobe pumps resemble external gear pumps, but have rotors with two, three, or four lobes in place of gears; the two rotors are both driven. Lobe pumps have a more pulsating output than external gear pumps and are less subject to wear. Lobe-type compressors are also used to pump gases; ...

heat exchangers, air-conditioning equipment, control air compressors, and miscellaneous equipment. The design of equipment rooms to host both pieces of equipment should consider the size and the weight of equipment, the installation and maintenance of equipment, and the applicable regulations to combusti...
Multistage air compressors:Multistage compressors are capable of delivering pressure and airflow levels beyond that of a single-stage unit. As a result, they are the ideal choice for demanding industrial environments that require running multiple tools at once, or tasks necessitating extremely high pre...
