US 7,841,194 B2 · Air conditioner and method of controlling such

Abstract

The invention provides an air conditioner that is capable of performing optimal control in accordance with the environment of an indoor space at startup, and a method of controlling such. The air conditioner forms a refrigerant circuit having a first heat exchanger, a second heat exchanger, thermistors, humidity sensors, a temperature sensor, ventilation fans, a compressor, a casing, a control unit, and the like. The control unit is connected to the temperature sensor, the humidity sensors, a storage unit, a timer, a manual input unit, air passageway switching mechanisms, a four-way switching valve, and an expansion valve. In the stage before the air conditioner starts normal operation after startup, the control unit performs a priority control operation that prioritizes either the sensible heat process or the latent heat process.

Dependent claims

An air conditioner that processes a sensible heat load and a latent heat load in an indoor space by performing a vapor compression type refrigeration cycle operation, comprising:

a control unit configured to perform a priority control operation that prioritizes processing at least one of said sensible heat load and said latent heat load from startup until a normal operation is started;
and
a detector unit configured to detect at least one of temperature and humidity in said indoor space,
during said priority control operation, said control unit switching from said priority control operation that prioritizes processing said sensible heat load to priority control operation that prioritizes processing said latent heat load, or from said priority control operation that prioritizes processing said latent heat load to said priority control operation that prioritizes processing said sensible heat load based on a detection result from said detector unit.

An air conditioner that processes a sensible heat load and a latent heat load in an indoor space by performing a vapor compression type refrigeration cycle operation, comprising:

a control unit configured to perform a priority control operation that prioritizes processing at least one of said sensible heat load and said latent heat load from startup until a normal operation is started;
an adsorbent that adsorbs moisture in the air;
and
a heat exchanger in which refrigerant flows in a refrigerant circuit,
when a batch switching time elapses, said control unit alternating said heat exchanger between a regeneration operation, in which said heat exchanger is made to function as a condenser and desorbs the moisture from said adsorbent, and an adsorption operation, in which said heat exchanger is made to function as an evaporator and adsorbs the moisture in the air onto said adsorbent.
