Abstract
A refrigerant cooling system includes multiple evaporator coils fed by one variable refrigerant metering device and one or more fixed refrigerant metering devices. To avoid condensed moisture on the coils from being entrained by the supply air and ultimately adversely increasing the humidity of a room or comfort zone of a building, the variable refrigerant metering device delivers refrigerant to the evaporator's lowermost coil at a superheat that is less than that of the other higher coils. To operate the refrigerant system at various loads, two or more compressors are selectively energized individually and in combination for various stages of capacity, while the variable refrigerant metering device is active at each stage. The refrigerant system may include multiple refrigerant circuits that are hermetically isolated from each other, or two or more of the circuits may be in fluid communication with each other.
