Embodiment Construction

[0046]Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

[0047]FIG. 1 is a diagram illustrating a water-source heat-pump type air conditioner according to an embodiment.

[0048]In FIG. 1, the water-source heat-pump type air conditioner according to the embodiment includes a single outdoor unit 100, and a plurality of indoor units 200 arranged in parallel to the outdoor unit 100. A water heat source 300 (i.e. a cooling tower) is connected to the outdoor unit 100 and is used to supply water (heat source water) into the outdoor unit 100 (more particularly, an outdoor heat exchanger).

[0049]The outdoor unit 100 includes a compressor 10, oil separator 25, 4-way valve 30, outdoor heat exchanger 40, outdoor expansion valve 45, receiver 50, economizer 60, electric expansion valve 62, solenoid valve 64, injection pipe 66, and accumulato...

Abstract

Disclosed herein is a water-source heat-pump type air conditioner in which a receiver is connected to a super-cooler or economizer, and a control method of the air conditioner to reduce the quantity of liquid refrigerant collected in the receiver during a cooling/heating overload operation. When a cooling/heating overload operation occurs, an electric expansion valve associated with the super-cooler or the economizer is opened by a predetermined opening degree, to bypass high-pressure liquid refrigerant collected in the receiver, thereby preventing a rapid pressure increase due to a great quantity of liquid refrigerant collected in the receiver.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 10-2010-0011650, filed on Feb. 8, 2010 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]Embodiments relate to an air conditioner and a control method thereof, which may reduce the quantity of liquid-phase refrigerant collected in a receiver during a cooling / heating overload operation.[0004]2. Description of the Related Art[0005]Generally, although heat naturally moves from a high temperature region to a low temperature region, moving heat from a low temperature region to a high temperature region may require certain external action. This is the principle of a heat pump. A heat-pump type air conditioner performs a cooling or heating operation via reversible switching of a heat transfer mechanism based on a refrigeration cycle consisting of compression-condensation-expansion-evaporation of...
