Method of torque prediction for automotive air conditioning compressor
The torque of a vehicular air-conditioning compressor is predicted by the steps of starting a vehicle air-conditioning system having an engine and engine control module for controlling multiple vehicle functions, calculating a steady state torque value using an rpm value from the engine, calculating an engine rpm transient torque value using the rpm value from the engine, calculating a electronic control valve current transient torque value using a current value applied to an electronic control valve, selecting a final torque value from a group consisting of the steady state torque value, the engine rpm transient torque value, and the electronic control valve transient torque value, and providing a final torque value to the vehicle engine control module to control a predetermined vehicle function.. .

Use of natural language in controlling devices
The invention discloses methods and apparatus based on tabular concepts which greatly simplify the configuration, maintenance and run-time operations of a broad range of electronic equipment control systems, including, but not limited to: (a) industrial controls, (b) supervisory control and data acquisition, such as heating, ventilation and air conditioning, and (c) home automation, including systems or stand-alone equipment, such as video recording devices. The tabular concepts of the invention are applied in three primary stages, namely (i) data input or configuration, including automated data population, (ii) generic operating rule application to tables of rules data variables, and (iii) english (or other) language translations of the current rule sets, for ease of verification.

Air conditioning apparatus
An object is to enable the dealer or user of an air conditioning apparatus to recognize that the heat dissipation amount of a heat exchange device is less than the heat dissipation amount expected of the air conditioning apparatus. A control device detects a hot water outflow temperature being a temperature of a fluid heated by a heat pump device, and a return temperature being a temperature of the fluid before being heated by the heat pump device, and checks whether or not a temperature difference between the detected hot water outflow temperature and the detected return temperature is smaller than a predetermined first value.

Air conditioning system using deep seawater
An air conditioning system using deep seawater, includes: a pump device pumping the deep seawater; a seawater-coolant heat exchanger performing heat exchange between a cold energy in the deep seawater and a coolant; an air conditioning heat exchanger performing heat exchange with the coolant cooled by the cold energy to release the cold energy in a target facility for cooling; a coolant circulating system circulating the coolant between the seawater-coolant heat exchanger and the air conditioning heat exchanger; and a controller driving the pump at timing when a variation is anticipated in the predicted heat loads based on the predicted heat load of the facility predicted from a prediction value of an operation status of the facility and a prediction value of a weather status at the place of the facilitate and a time lag due to a length of the pipe in the coolant circulating system.. .

Sub-cooled condenser having a receiver tank with a refrigerant diverter for improved filling efficiency
A sub-cooled condenser for an air conditioning system, having a condenser portion, a sub-cooler portion located below that of the condenser portion, an adjacent receiver tank having a first fluid port in hydraulic connection with the condenser portion and a second fluid port in hydraulic connection with the sub-cooler portion, and a refrigerant diverter assembly disposed in the receiver tank. The refrigerant diverter assembly is configured to divert a refrigerant from the first fluid port to a location beneath the surface level of a refrigerant retained within the receiver tank without impacting the surface level.
