Problems solved by technology

This makes it impossible to fully control the temperature and dehumidification of the air blown in the room
Since the compressor is single and operates at a constant speed, it cannot fully control the dehumidification capacity according to the difference between the set humidity and the room humidity

Abstract

An air conditioner, comprises a compressor, an outdoor heat exchanger, an outdoor fan, a first indoor heat exchanger and a second indoor heat exchanger, a dehumidifying restricting device, and an indoor fan. The air conditioner includes a refrigerant flow path on the upstream side of the air flow in the first indoor heat exchanger, which is used as a refrigerant entrance in the dehumidifying and cooling operation of the first indoor heat exchanger, and then as a refrigerant export in the heating operation, so as to form a refrigerant flow in a flowing system; other refrigerant flow pathes disposed on the downstream side of the refrigerant in the dehumidifying and cooling operation of the first indoor heat exchanger, so as to form refrigerant flows in two or more flowing systems; and another refrigerant flow path with two or more flowing systems in the second indoor heat exchanger, which is provided in the air flow downstream side of the refrigerant with two or more flowing systems.

Description

[0001] This application is a divisional application of the application dated June 1, 1994, application number 02131692.9, and titled "air-conditioning equipment". technical field [0002] The present invention relates to an air conditioner and its operating method. More particularly, the present invention relates to an air conditioner and its operating method in which dehumidification operation can be performed with little cooling to little heating over a wide temperature range. Background technique [0003] As a conventional air conditioner in which a dehumidification operation is performed to reduce humidity, there is known a system in which air cooled by an evaporator is reheated by an electric heater; Heat of condensation reheats. When comparing these two systems with each other, especially from the point of view of energy saving, the latter is considered to be better because the former consumes a lot of power. [0004] In addition, in Japanese Patent Unexamined Public...
