Abstract

An air conditioner and a method for controlling the same are disclosed. The air conditioner implements a multistage expansion scheme by implementing serial connection between electronic expansion valves including in the R410A refrigerant-based air conditioner, and thus guarantees an optimum compression ratio in all cooling / heating load regions. Although cycle characteristics are changed by changing R410A refrigerant to R32 refrigerant, the air conditioner optimizes the cycle simply by controlling a degree of opening of electronic expansion valves, respectively. Since the cycle optimization isimplemented using the multistage expansion scheme in which legacy electronic expansion valves are coupled in series, the design modification is minimized without design modification of requisite constituent elements such as a heat exchanger, system implementation is facilitated, resulting in high efficiency in cost and productivity. Cooling / heating performance improvement and reliability guaranteeare achieved under all load conditions, resulting in increased system efficiency.

Description

technical field [0001] Embodiments of the present disclosure relate to a multi-stage expansion air conditioner and a method for controlling the same. Background technique [0002] An air conditioner includes an outdoor unit performing heat exchange between outdoor air and refrigerant and an indoor unit performing heat exchange between indoor air and refrigerant. An air conditioner is a device that cools or heats indoor air using movement of heat generated during evaporation and condensation of a refrigerant circulating 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 a major cause of ozone depletion in...
