Now focus all attention on the heating part of the heating / cooling conditioner Structure and function. Figure i is a partial half-section front view, showing a conventional cooling / heating air conditioner, where the cooling part is not shown here. As shown in Figure 1, this heating part The component system includes a heat burner 11, a heat exchanger 12, and a fuel pump 13 installed in the main body i, and a fuel tank 14 installed outside the main body 1. The fuel stored in the fuel tank 14 is provided by The fuel pump 13 is supplied to the burner η. The heat generated by burning the fuel increases the temperature of the air around the heat exchanger 12. At the same time, the fan 2 installed at a lower position in the main body 1 starts to operate. Therefore, in the room The air is drawn into the main body through an air inlet (not shown) on the front bottom of the main body 1 1 and the air heated by the heat exchanger 12 passes through the exhaust port la on the upper part of the front side of the main body 1 and is then discharged out of the room. However, such a conventional heating / cooling air conditioner has the following disadvantages. In order to heat the air, traditional heating / cooling air conditioners must burn fuel ', but this may cause pollutants such as coal ash or some substances that will pollute the environment due to incomplete combustion. The 'heating / cooling air conditioner must be placed in a place with poor ventilation' and the place where the heating / cooling air conditioner is placed is very limited 'because a pipe that exhausts the burning gas to the outside is necessary ________ This paper Xjt is applicable Jia Pi (CNS) A4 «^ (21GX297 mm ~-(谙 first read the note f on the back before filling in this page)

Printed by Shellfish Consumer Cooperative of Central Bureau of Standards, Ministry of Economic Affairs V. Invention Description (4) The air in the main body 1 is sucked in through the air inlet in the main body 1 and exhausted outside through the air outlet la. Then, the heating / cooling air conditioner of the present invention is the same as the conventional heating / cooling type air conditioner and cooling type air conditioner. Therefore, for cold operation or cooling, the following is the description of the heating part. In this province, when the electric water heater 21 starts to operate, the electric heater inside the inner heater 21 heats up. After being heated in this way, the pump circulates pump_Na to 敎 ㈣23 ', and the water supplied to the heat exchanger 23 is circulated in the pipe ❿ installed in the heat exchanger 23', thereby increasing the temperature of the pipe and air. Then, the water flowing out of the heat exchanger 23 is returned to the electric water heater through the circulation, is reheated, and is then supplied to the heat exchange 23 through the circulation pump 22. When the temperature of the water in the pipeline 23a circulating through the heat exchanger 23 reaches approximately 4 ° C to 5 ° C, and preferably exceeds 45 ° C, the temperature of the fan 2 is sensed by the second temperature sensor. The operation is started. The air heated by the heat exchanger 23 is discharged into the room through the exhaust port la by the action of the blower fan 3. Then the air in the room is drawn into the main body again through the air inlet lb in the main body 1. The inside of the vessel is discharged after being heated by the heat exchanger 23 through the exhaust port ia. However, when the temperature of the water in the heat exchanger 23 reaches about 9 (TC ~ 100 ° C, preferably more than 95 ° C) At this time, the operation of the electric heater installed in the electric water heater 21 is stopped by the action of the third temperature sensor. This is because people in the room may be burned because the temperature of the sent wind is too high.
