Method and system for optimizing a speed of at least one of a variable speed compressor and a variable speed circulation fan to improve latent capacity

摘要

An HVAC system includes an evaporator coil and a metering device. The HVAC system includes a variable-speed circulation fan and a condenser coil fluidly coupled to the metering device. A variable-speed compressor is fluidly coupled to the condenser coil and the evaporator coil. A controller is operatively coupled to the variable-speed compressor and the variable-speed circulation fan. A second temperature sensor is disposed in an enclosed space. The second temperature sensor measures temperature of the enclosed space and transmits the temperature of the enclosed space to the controller. The controller determines if the temperature of the enclosed space is below a minimum threshold. Responsive to a determination that the temperature of the enclosed space is below the minimum threshold, the controller modulates at least one of a speed of the variable-speed compressor and the variable-speed circulation fan to lower a discharge air temperature.
