Air Conditioner with Freeze Heat Exchanger {AN AIR HANDLING UNIT HAVING A HEAT EXCHANGER FOR PREVENTION FROZEN}

The present invention relates to an air conditioner equipped with an anti-freeze heat exchanger in which an electric heater is attached to the heat exchanger in order to always maintain the refrigerant in the heat exchanger used in the air conditioner above the freezing point. It relates to an air conditioner equipped with a heat exchanger for preventing the freezing of the winter made to easily install the heat exchanger of the air conditioner by configuring the heat exchanger as a socket type heat exchanger using a fastening method.

In general, an air conditioner is a device used to maintain an indoor air temperature, humidity, cleanliness, and air flow distribution optimally for a person or an article for a purpose.

An air conditioner is composed of a heat source device such as a boiler or a refrigerator, an air cooler and heater, a temperature controller, an air conditioner such as an air filter, a heat transport system such as a pipe, a duct, a fan, and a control device for controlling them.

1 is a view showing an air conditioner equipped with a conventional heat exchanger, wherein external air and indoor air are introduced into the air mixing box 2, and the introduced external air and internal air pass through the air filter 3 to remove impurities. And through the heat exchanger (4), the air is at an appropriate temperature, forcibly blown by the blowing fan (6), and supplied to the room through a duct (not shown).

However, since the heat exchanger used in the conventional air conditioner is made to circulate the liquid inside the tube using a tube type, a problem arises in that the liquid in the heat exchanger tube is rapidly frozen by cold air in winter to rupture a part of the heat transfer tube. In this case, the expensive heat pipe had to be replaced, which increased the economic burden of the user, and the replacement of the ruptured parts required professionalism, and thus there was a problem such that ordinary people could not easily replace it.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an air conditioner having a freezing heat exchanger that can directly heat the air coming from the outside of the air conditioner.

The present invention aims to provide a high efficiency air conditioner by miniaturizing the size of the heat exchanger while improving the thermal efficiency.

In addition, the present invention is to provide an air conditioner with a freeze-proof heat exchanger made of a socket-type fastening and assembling simple installation, repair and transport installation to the header of the heat exchanger.

In addition, the present invention is to reduce the repair cost by preventing the freezing of the heat exchanger that occurs easily in winter, and to provide an air conditioner that lasts a long life.
