Abstract

PURPOSE: An air conditioner for a container is provided to promote perfect maintenance of regular temperature and regular humidity and to be useful for a manless container structure through automatic remote control. CONSTITUTION: An economizer damper(8) is mounted in the center(B) of an air conditioner body. The economizer damper is communicated with the lower portion of an air filter(10) to suck external air. The economizer damper has a temperature sensor(9) connected to a control unit(7). The air filter has multi-layered corrugated form including vertical corrugation. External air is sucked through an intake grill(1) by a blower(11) and raised up to the air conditioner body. The raised air is filtered by the air filter and flowed to an evaporator(13). Low-temperature low-pressure refrigerant of an expansion valve is changed into gas phase by absorbing heat of the air. The cooled air is discharged out of a discharge grill(14) by another blower(12). If the external air has sufficient low temperature, the system controller(7) stops a refrigerant system including a compressor(2) and air-conditions the indoor space simply with the external air through the economizer damper.

In addition, energy can be saved through air-conditioning by outside air when the outside temperature is low, The purpose of the present invention is to provide a container air conditioner that can create a comfortable indoor environment by having a high clean air purification function.

In order to achieve the above object, the present invention integrates an indoor unit and an outdoor unit, and includes a control unit that enables a batch control and a remote control through a computer or a computer and a modem, and stops the operation of the compressor when the outside temperature is low. When the economizer damper is automatically switched to suck and supply the outside air, the air conditioner performs air conditioning only, and a pleated filter is employed.
