There are four basic types of compressors used in vapor compression chillers: Reciprocating compression, scroll compression, screw-driven compression, and centrifugal compression are all mechanical machines that can be powered by electric motors, steam, or gas turbines.

Centralized chillers generally have capacities ranging from ten tons to hundreds or thousands of tons. Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional (CII) facilities. Water chillers can be water-cooled, air-cooled, or evaporatively cooled.

Definition Mechanical Contractor I'm sorry to infiltrate this forum, but I thought you guys could help me with a question I had. What's the difference between a mechanical contractor and a plumber?

Re: Definition Mechanical Contractor A mechanical contractor does do electrical and plumbing but just on the system they are working on. They do heating, AC, and ventalation.

For medium to large chillers this should range from 3.5 to 7.0, with higher values meaning higher efficiency. Chiller efficiency is often specified in kilowatts per refrigeration ton (kW/RT).

York International water-cooled 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).

Re: Definition Mechanical Contractor. A mechanical contractor does do electrical and plumbing but just on the system they are working on. They do heating, AC, and ventalation. Most plumbers are also mechanical contractors which is why most people think plumbers do HVAC. I worked with a mechanical contractor yesterday and today on a cold storage building used for apples on a farm.

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. As a necessary by product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes. Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional facilities.
