Abstract

The invention provides an air conditioner which can save energy and lower equipment cost and operation cost. In order to condition air by inner circulation of an air-conditioned area (A) in a large area, the conditioner comprises: a cold-heat water component (1) provided with a cold-heat water coil using low-usable energy cold-heat water and air sucked from the air-conditioned area to exchange heat; a heat pump side component (2) provided with an air-supplying air heat exchanger using a circulation heat medium with usable energy thereof higher than that of the low-usable energy cold-heat water and air sucked from the air-conditioned area to exchange heat; a blowing component (3) blowing the air passing through the cold-heat water coil and the air passing through the air-supplying air heatexchanger to the air-conditioned area; a heat pump (14) for a compressed air heat source, provided with the air-supplying air heat exchanger, and circulating the circulation heat medium; and a control unit (23) controlling flux of the cold-heat water flowing through the cold-heat water coil and the compression volume of a compressor of the heat pump.

Description

technical field [0001] The present invention relates to an air conditioner that circulates air in an area to be conditioned to condition the air. Background technique [0002] In the past, air conditioning (hereinafter referred to as "air conditioning") in large spaces such as factories, large stores, supermarkets, and gymnasiums was carried out with hot and cold water central air conditioners such as air conditioning equipment to regulate the entire large space. The hot and cold water central air conditioner adopts such a structure: through the cold and hot water coils in which cold water or hot water (hereinafter referred to as "hot and cold water") flows as heat source water, the heat source water and the The air sucked into the area (return air) is heat-exchanged and supplied to the area to be conditioned, and the air is circulated in the area to be conditioned to perform air conditioning (hereinafter referred to as cycle air conditioning) (see Patent Documents 1 to 3). ...
