Abstract
A heating ventilation and cooling system includes a cooling source and/or a heating source, and a controller. The cooling and/or heating sources are configured to respectively cool and heat an enclosed space. The controller is configured to receive an apparent temperature set point. The controller is further configure to operate the cooling and/or heating sources to maintain an absolute air temperature that is different from the apparent temperature set point.
Claims12
A climate control system, comprising:
- a cooling source, including a compressor, configured to cool an enclosed space;
- a heating source, including a furnace, configured to heat the enclosed space;
- and
- a controller coupled to the cooling source and the heating source, the controller configured to:
- receive a first apparent temperature set point, a second apparent temperature set point, a first time, and a second time, the first apparent temperature set point different from the second apparent temperature set point, the first time different from the second time;
- receive a first measured relative humidity of the enclosed space at the first time, a first measured air speed in the enclosed space at the first time, and a first measured radiant energy of the enclosed space at the first time;
- receive a second measured relative humidity of the enclosed space at the second time, a second measured air speed in the enclosed space at the second time, and a second measured radiant energy of the enclosed space at the second time;
- determine a first plurality of combinations of absolute air temperature, air speed, radiant energy, and relative humidity, wherein the absolute air temperature, air speed, radiant energy, and the relative humidity of each combination of the first plurality of combinations correspond to the received first apparent temperature set point;
- determine a second plurality of combinations of absolute air temperature, air speed, radiant energy, and relative humidity, wherein the absolute air temperature, air speed, radiant energy, and the relative humidity of each combination of the second plurality of combinations correspond to the received second apparent temperature set point;
- determine if a first current time is the first time;
- in response to a determination that the first current time is the first time:
- determine a combination of the first plurality of combinations wherein the relative humidity of the determined combination of the first plurality of combinations is closer to the measured relative humidity of the enclosed space than the relative humidities of the other combinations of the first plurality of combinations;
- and
- operate the cooling source, including the compressor, and the heating source, including the furnace, to maintain an absolute air temperature within the enclosed space at the absolute air temperature of the determined combination of the first plurality of combinations;
- determine if a second current time is the second time;
- and
- in response to a determination that the second current time is the second time:
- determine a combination of the second plurality of combinations wherein the relative humidity of the determined combination of the second plurality of combinations is closer to the measured relative humidity of the enclosed space than the relative humidities of the other combinations of the second plurality of combinations;
- and
- operate the cooling source, including the compressor, and the heating source, including the furnace, to maintain an absolute air temperature within the enclosed space at the absolute air temperature of the determined combination of the second plurality of combinations.
