System and method for calculating the thermal mass of a building

The invention comprises a system for calculating a value for the effective thermal mass of a building. The climate control system obtains temperature measurements from at least a first location conditioned by the climate system. One or more processors receive measurements of outside temperatures from at least one source other than the control system and compare the temperature measurements from the first location with expected temperature measurements. The expected temperature measurements are based at least in part upon past temperature measurements obtained by said HVAC control system and said outside temperature measurements. The processors then calculate one or more rates of change in temperature at said first location.

Method of transporting or storing perishable produce

The invention allows cool rooms or sea containers designed for frozen goods to handle produce requiring more precisely controlled temperatures and conditions, e.g., vegetables and fruits requiring temperatures in the chilling range and often also needing control or modification of the atmosphere. Each load of produce (100) (e.g. of pallet size) is held in the sea container or cool room but is sealed from the air of the refrigerated environment by, for example, a plastics bag (56). The atmosphere within the bag is then circulated by a fan (12) (or by convection currents from a heating element) so as to pass through the load and around it via ducts (30) provided adjacent the bag (56). Heat exchange (50) between the circulating gas and the refrigerated environment, via the plastics film, serves to cool the load. However, if cooling is excessive a heating element can be used to raise the temperature of the circulating atmosphere. Gas composition of the atmosphere can be controlled by scrubbing, flushing, etc. via pipes from a central unit or at each load individually or by choosing semi-permeable plastic for the sealing bags.

Air handling controller for HVAC system for electric vehicles

An air-flow management system for controlling the supply air to a motor vehicle passenger compartment is disclosed. The air-flow management system includes a reversible heat pump system for transferring heat energy between an outside environment and a refrigerant. Air from the outside environment, fresh air, and from the passenger compartment, recirculated air, is forced through the air-flow structure by a blower resulting in the transfer of heat energy between the refrigerant and the passenger compartment. A recirculation door provides a means for controlling the mixture of fresh air to recirculated air that flows through the air-flow structure. The position of the recirculation door is selectable by a controller to prevent fogging during the transition from cooling mode to heating mode, minimize the energy expended conditioning the passenger compartment air, and prevent the backflow of unconditioned outside air from the fresh air duct into the recirculation duct.

Energy reducing retrofit method for a constant volume HVAC system

An energy-reducing method and apparatus for retrofitting a constant volume HVAC system, with or without an economizer, that provides heating, cooling, and ventilation to occupants within a building space. The present invention includes the introduction of a programmable logic controller and variable frequency drive (VFD) that takes control of the existing fan, heating, cooling, and optional economizer operation. The controller is programmed for the reduction of fan speed in the heating and cooling modes. The reduction of the fan speed in the ventilation mode when the 100% operation is not needed saves significant energy of the existing constant volume HVAC system where the fan motor is designed to run 100% of the time. The fan speed may be further reduced upon a reduction in sensed occupancy levels of the space, such as with a CO2 sensor. Additionally, the fan speed may be reduced in the heating and / or cooling mode to further reduce energy consumption. The controller may also be programmed and equipped with sensors to allow simultaneous mechanical compressor cooling and economizer free cooling operation, for the operation of the economizer in response to the monitoring of outside air and return air to determine the preferred source for cooling operations, to keep the outside air damper closed during the unoccupied heating modes such as morning warm-up, and / or to provide fault detection. The retrofit method and apparatus may be employed in a stand-alone or networked version.

Temperature-controlled chuck with recovery of circulating temperature control fluid

A system and method for controlling temperature in a workpiece chuck are described. A fluid circulation system circulates a temperature control fluid, such as an engineered HFE fluid, through te workpiece chuck. A fluid recovery system coupled to the fluid circulation system recovers a portion of the temperature control fluid from the fluid circulation system by circulating a gas through the fluid circulation system including fluid tubes and fluid passages in the chuck. The gas, which can be air, carries a portion of residual or excess fluid through the fluid circulation system as it is circulated. The residual fluid is carried back to a reservoir such that it can continue to be used to control temperature of the chuck. Where gas and temperature control fluid vapors are displaced from the reservoir, they are routed through a suction line heat exchanger which condenses the vapor. The gas and condensed fluid are separated in a fluid separator. The separated fluid is returned to the reservoir, and the separated air can be vented to the atmosphere.

Temperature setting method of heat processing plate, temperature setting apparatus of heat processing plate, program, and computer-readable recording medium recording program thereon

An object of the present invention is to perform temperature setting of a heating plate so that a wafer is uniformly heated in an actual heat processing time. The temperature of a wafer is measured during a heat processing period from immediately after a temperature measuring wafer is mounted on the heating plate to the time when the actual heat processing time elapses. Whether the uniformity in temperature within the wafer is allowable or not is determined from the temperature of the wafer in the heat processing period, and if the determination result is negative, a correction value for a temperature setting parameter of the heating plate is calculated using a correction value calculation model from the measurement result, and the temperature setting parameter is changed.
