<p>The present invention relates to a temperature changing device such as a normal refrigerator, a freezer, an air conditioner, and a boiler having a sensor and a control unit connected to an intake-discharge device (120) such as a compressor or a motor in accordance to a device operating the intake-discharge device (120) rotating, receiving, and sending an inner temperature changing medium of pipes (130, 131, 140, 141) connected to an indoor and an outdoor unit installed in an indoor space wherein humans or animals stay or in a storage room (110). More specifically, the present invention includes: a valve connecting and U-turning, or shutting off the pipes of the storage room (110) or indoor unit, or the outdoor unit; the sensor sensing an inner temperature of the storage room or an indoor temperature; a contact body preventing an intake of heat from the outside to the indoor unit, and additionally changing a temperature of the outdoor unit. The present invention additionally changes a temperature of the outdoor unit, changing a temperature of an external pipe at a desirable temperature, and connects the external pipe to the storage room (110), the indoor unit, or the indoor pipe; thereby being advantageous in preserving a stored object much better by maintaining the inner temperature of the storage room (110) or preserving the indoor temperature better. In addition, the present invention is capable of reducing a frequency of use of the compressor or motor, thereby obtaining an effect of remarkably saving electricity.</p> |
