AIR CONDITIONER FOR FAN COIL TYPE RADIATION AIR CONDITIONING PANEL WITH HEAT PUMP

摘要

PROBLEM TO BE SOLVED: To reduce installation costs of an air conditioner and to minimize heat recovery loss of hot/cold water in the air conditioner.SOLUTION: This air conditioner 1 includes a fan coil disposed in hot/cold water piping 20, a heat pump water-refrigerant heat exchanger 12 exchanging heat between hot/cold water in the hot/cold water piping 20 and a refrigerant of a compressor 10, a radiation air conditioning water-water heat exchanger 33 exchanging heat between circulated water in a circulation water channel 31 and the hot/cold water in the hot/cold water piping 20, a radiation air conditioning water-refrigerant heat exchanger 34 exchanging heat between the refrigerant in refrigerant piping 15 and the circulated water in the circulation water channel 31, and a refrigerant-air heat exchanger 14 exchanging heat between the air distributed from an air blower 21 and the refrigerant in the refrigerant piping 15. The radiation air conditioning water-water heat exchanger 33 is disposed between the fan coil 22 and the heat pump water-refrigerant heat exchanger 12 in the hot/cold water piping 20, and the hot/cold water piping 20 is provided with a bypass passage 35 bypassing the fan coil 22.
