Patent ID: 7836712

Claim:
An air conditioning apparatus comprising: an air-conditioning unit including a cooling coil as a heat exchanger; a blower; a chiller; and a coolant pump, wherein the air-conditioning unit is configured so that the coolant pump pumps the coolant cooled by the chiller to the cooling coil, and the cooling coil cools the air through heat exchange between the coolant and the air, and the cooled air is supplied into a room by the blower for air-conditioning purposes, wherein the air-conditioning unit comprises only the cooling coil as the heat exchanger, and the air conditioning apparatus further comprises a controller for adjusting a ratio of a dry coil part and wet coil part of the cooling coil by controlling the coolant temperature of the chiller, the coolant flow rate of the coolant pump, and the air flow rate of the blower in accordance with a ratio of the sensible heat load and the latent heat load in the room.
