Title:
AIR CONDITIONING FACILITY FOR FRONT CHAMBER OF LOW-TEMPERATURE WAREHOUSE AND AIR CONDITIONING METHOD
Document Type and Number:
Japanese Patent JP2014153017
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve further energy saving of an air conditioning device by highly efficiently utilizing heat energy that outside air retains, when bringing a front chamber neighboring to a cold insulation chamber of a low-temperature warehouse, into positive pressure with temperature and humidity adjusted air by causing the adjusted air flow to the front chamber.SOLUTION: Outside air OA is led into an air flow passage 42 by an air blower 44. Second air a2 reflowing from a reflow passage 54 in an inlet of the air blower 44 is mixed with the led-in outside air OA. A part of mixed air is branched to a branch flow passage 48 at an upstream side of a cooler 46. First air a1 cooled and dehumidified by the cooler 46 and the second air a2 branched to the branch flow passage 48 are heat-exchanged by a heat exchanger 50. The first air a1 heated by the heat exchanger 50 is sent to a cargo-handling chamber 64, and the second air a2 cooled and dehumidified by the heat exchanger 50 reflows through a reflow path 54 to the inlet of the air blower 44.
