Embodiment Construction

[0052] The first invention includes a temperature distribution detection unit that detects a temperature distribution of a room, a refrigerant leakage detection unit that detects refrigerant leakage, an air blowing unit, an air blowing control unit that controls the air blowing unit, and an airflow direction control unit that controls the airflow direction of the air blowing unit , when the refrigerant leakage detection unit detects refrigerant leakage, the leaked refrigerant is diffused by the air supply control unit and / or the air direction control unit. Accordingly, the air conditioner diffuses the refrigerant in a direction different from that of the occupant, thereby preventing the refrigerant from stagnating near the occupant. Furthermore, stagnation of the refrigerant and decomposition of the refrigerant by the heat source device can be prevented.

[0053] The second invention, in the first invention, includes: a refrigerant leakage alarm unit that issues an alarm when ...

Abstract

Disclosed is an air conditioner provided with: a temperature distribution detection means (12) for detecting the temperature distribution of a room (1); a coolant leak detection means (13) for detecting coolant leaks; a ventilation control means (17c) for controlling a ventilation means (14); and an airflow direction control means (17d) for controlling the airflow direction of the ventilation means (14). When the coolant leak detection means (13) detects a coolant leak, the ventilation control means (17c) and the airflow direction control means (17d) disperse coolant in a direction different from that of a heat source device (4) or an occupant (3) etc. detected by the temperature distribution detection means (12), and safety is thereby improved.

Description

technical field [0001] The present invention relates to an air conditioner capable of improving energy efficiency and safety. Background technique [0002] Currently, HFC-based fluorocarbon (freon) refrigerants that do not deplete the ozone layer are used as refrigerants for air conditioners and the like. However, since this HFC refrigerant has a very high global warming coefficient, it is also subject to emission restrictions in order to prevent global warming. Therefore, the use of natural refrigerants such as HFC refrigerants and hydrocarbon refrigerants with a low global warming coefficient as refrigerants for refrigeration and air-conditioning devices has been considered. However, among the hydrocarbon refrigerants and HFC refrigerants, refrigerants such as R32, which have less impact on global warming, are flammable in nature. Therefore, in order to prevent the danger of refrigerant leakage, a primary side cycle using a flammable refrigerant and a secondary side cycl...
