Abstract
A control system for controlling an output for at least one compressor includes a control unit that receives an indoor set point and an outdoor ambient temperature. The control unit determines a load request based on the indoor set point and the outdoor ambient temperature without considering an indoor room temperature. The at least one compressor receives control commands from the control unit based on the load request.
Claims20
A control system for controlling an output for at least one compressor, said control system comprising:
- a control unit receiving an indoor set point and an outdoor ambient temperature and determining a load request based on the indoor set point and the outdoor ambient temperature and not based on an indoor room temperature;
- and at least one compressor receiving control commands from the control unit based on the load request;
- and wherein the control unit includes a sensible load determination unit that determines a sensible load request based on a sensible load model, the indoor set point, and the outdoor ambient temperature, the sensible load model being determined based on at least one of a type and a location of a plurality of building walls, a size of the building, a number and a size of a plurality of building rooms, a number, a size, and a location of a plurality of building windows, number and a location of a plurality of air conditioning vents, an amount, a type, and a location of insulation, a type of furniture, a regional location of the building, a number of people living or working in the building, a number of electronics used in the building, and a sun load on the building.
A method for controlling an output for at least one compressor comprising:
- receiving, by the controller, an indoor set point and an outdoor ambient temperature;
- determining, by the controller, a load request based on the indoor set point and the outdoor ambient temperature and not based on an indoor room temperature;
- and controlling, by the controller, at least one compressor based on the load request;
- and further comprising determining, by the controller, a sensible load request based on a sensible load model, the indoor set point, and the outdoor ambient temperature, the sensible load model being determined based on at least one of a type and a location of a plurality of building walls, a size of the building, a number and a size of a plurality of building rooms, a number, a size, and a location of a plurality of building windows, a number and a location of a plurality of air conditioning vents, an amount, a type, and a location of insulation, a type of furniture, a regional location of the building, a number of people living or working the building, a number of electronics used in the building, and a sun load on the building.
