TEST CHAMBER WITH TEMPERATURE AND HUMIDITY CONTROL

摘要

A test chamber that is capable of operating in a mode where the temperature of the chamber is efficiently cooled without removing a substantial amount of moisture from the air. The test chamber includes a structure defining a work space having air, and a temperature control system. The temperature control system includes a heat exchanger positioned to communicate with the air in the work space, a source of cold fluid coupled to the heat exchanger, a source of hot fluid coupled to the heat exchanger, and a controller for controlling a mixture of cold fluid and hot fluid entering the heat exchanger The controller is programmed such that the temperature of the mixture entering the heat exchanger is controlled to limit a temperature differential between the heat exchanger and the air in the work space
