Title
(EN) Desk mounted personal environment system
Abstract
(EN)

A personal environment system for creating a user-definable local environt within a localized zone in an ambient space, comprises a modular housing mountable in said localized zone and having an air inlet, an air outlet incorporating a diffuser for distributing conditioned air into said localized zone, an air flow channel between said air inlet and said air outlet, and a channel for a thermal fluid for supplying or carrying away heat. a blower means causes air to flow through the air channel. A heat exchanger between the air flow channel and the thermal fluid channel and includes a thermoelectric heat pump to effect transfer of heat between air flowing through the air flow channel and the thermal fluid channel. A control unit permits the user to set the amount of heating or cooling applied by the heat pump to air flowing through said air channel to permit the user to control the air temperature within the localized zone according to personal comfort requirements independently of the general air temperature of the ambient space.
