Abstract

An air conditioner and a method for controlling the same are disclosed. This air conditioner implements a multi-stage expansion scheme by realizing a series connection between electronic expansion valves included in an R410A refrigerant-based air conditioner, and thus ensures an optimal compression ratio in all cooling / heating load areas. Although the cycle characteristics are changed by changing the R410A refrigerant to the R32 refrigerant, the air conditioner only optimizes the cycle by individually controlling the opening of the electronic expansion valve. Since cycle optimization is realized by using a multi-stage expansion scheme coupled in series with conventional electronic expansion valves, design modifications are minimized without design modifications to necessary constituent elements (such as heat exchangers), which facilitates system implementation, High efficiencies in cost and productivity are thereby obtained. Improved cooling / heating performance and guaranteed reliability under all load conditions result in increased system efficiency.

Description

technical field [0001] Embodiments of the present disclosure relate to a multi-stage expansion type air conditioner and a method for controlling the same. Background technique [0002] An air conditioner includes an outdoor unit that performs heat exchange between outdoor air and refrigerant and an indoor unit that performs heat exchange between indoor air and refrigerant. An air conditioner is a device that cools or heats indoor air using the movement of heat generated during evaporation and condensation of a refrigerant that circulates in a refrigerant cycle including a compressor, a condenser, an expansion device, and an evaporator. [0003] As a representative refrigerant for supplying thermal energy of indoor air to an outdoor space or supplying thermal energy of outdoor air to an indoor space using the above air conditioner, a well-known chlorofluorocarbon (CFC)-based refrigerant as Freon gas is used. [0004] However, since CFC-based refrigerants are the main cause o...
