An autonomous ventilation system includes a variable-speed exhaust fan, a controller, an exhaust hood, and an infrared radiation ('IR') sensor. The exhaust fan removes air contaminants from an area. The controller is coupled to the exhaust fan and adjusts the speed of the exhaust fan. The exhaust hood is coupled to the exhaust fan and directs air contaminants to the exhaust fan. The IR sensor is coupled to the controller, detects changes in IR index in a zone below the exhaust hood, and communicates information relating to detected changes in IR index to the controller. The controller adjusts the speed of the exhaust fan in response to information relating to detected changes in IR index. The autonomous ventilation system also includes an alignment laser to indicate a point at which the IR sensor is aimed and a field-of-view ('FOV') indicator to illuminate the zone in which the IR sensor detects changes in IR index.

An autonomous ventilation system includes a variable-speed exhaust fan, a controller, an exhaust hood, and a spillage sensor. The exhaust fan removes air contaminants from an area. The controller is coupled to the exhaust fan and adjusts the speed of the exhaust fan. The exhaust hood is coupled to the exhaust fan and directs air contaminants to the exhaust fan. The spillage sensor is coupled to the controller, detects changes in an environmental parameter in a spillage zone adjacent to the exhaust hood, and communicates information relating to detected changes in the environmental parameter to the controller. The controller adjusts the speed of the exhaust fan in response to information relating to detected changes in the environmental parameter.

A modular evaporator which can be assembled from a number of standard modules is provided. Depending on the requirements, the modular evaporator can be assembled to meet a wide range of design cooling loads. Additionally, the modular evaporator is capable of generating and holding ice for thermal storage purposes, eliminating the need for external ice storage tanks. Furthermore, the heat transfer and thermal storage fluid for the evaporator can simply be water which considerably simplifies the system, lowers the cost, and increases the efficiency of the heat transfer loop.

Modular evaporator and thermal energy storage system for chillers

The invention comprises a Thermal Energy Module comprising a tank adapted to hold water or other heat transfer medium (such as water), a water loop for introducing the heat transfer medium and removing the heat transfer medium, and a refrigeration loop comprising a heat exchanger further comprised of an inlet manifold, a heat transfer structure (such as a micro channel or pipe-in-plate panel) and an outlet manifold wherein the heat exchanger is adapted to transfer thermal energy between the heat transfer structure and the heat transfer medium. The Thermal energy Module may be utilized as a component of a heating and cooling system. Such a Thermal Energy Module may be used to store thermal energy during the day and return it during the evening. Additionally, such a Thermal Energy Module may be implemented as an array of such modules and such array of modules may be adapted to fit within the walls of a building or structure.

Thermal energy module

A control system measures the pressure/temperature of the refrigerant within a Thermal Energy Module having a heat exchanger and calculates the thickness of ice within the Thermal Energy Module. A controller calculates an integral starting from the moment when ice accumulation begins: I(t)=&#x222b;Tr(&#x3c4;)*d&#x3c4; where Tr is the refrigerant saturation temperature changing with time t. The thickness of the ice on one side of the heat exchanger can be calculated using the following formula: X=&#x221a;(2*I*K*Ui/&#x3c1;i/ci) where Ui is the thermal conductance of ice &#x3c1;i is the density of the ice Ci is the latent heat of the ice K is a correction coefficient associated with the type of the heat exchanger.

Method of control of thermal energy module background of the invention

In accordance with the present invention, a method for automated parameter measurement includes strategically positioning an identifier tag at a location proximate a first object. The identifier tag stores location-specific information associated with the first object. A sensor in communications with the identifier tag receives the location-specific information from the identifier tag. Additionally, the sensor is used to collect quantitative data associated with a first parameter from the first object. The location-specific information received from the first identifier tag is used to process the quantitative data.
