Abstract

본 발명은 냉/난방 에어콘의 히터운전 제어방법에 관한 것으로,실외배관에 히터를 설치하여 배관온도 및 실외온도에 따라 히터를 제어하여 한 겨울에도 쾌적한 난방을 할 수 있도록 한 것이다.The present invention relates to a heater operation control method of the cooling / heating air conditioner, by installing a heater in the outdoor pipe to control the heater in accordance with the piping temperature and the outdoor temperature to enable a comfortable heating even in the winter.

이와같은 본 발명은 난방시 압축기가 운전중이 아니거나 제상운전일 경우 히터를 정지하고 타이머를 클리어하는 제1스텝과,난방시 압축기가 운전중이고 제상운전이 아닐경우 히터가 운전중인가를 판단하는 제2스텝과,제2스텝에서 히터가 운전되지 않을때 배관온도가 기준온도(T₁)보다 높으면 타이머를 클리어하고,낮을 경우 일정시간(m분)경과 후 외기온도를 기준온도(t₂)와 비교하는 제3스텝과,제3스텝에서 외기온도가 기준온도(t₂)보다 낮으면 배관온도가 기준온도(t₄)보다 낮을때만 히터를 운전하고 외기온도가 기준온도(t₂)보다 높으면 배관온도가 기준온도(t₃)보다 낮을때 히터를 운전하는 제4스텝과,상기 제2스텝 또는 제4스텝에서 히터운전중 외기온도가 기준온도(t₅)보다 낮으면 배관온도가 기준온도(t₇)보다 높을때 또는 외기온도가 기준온도(t₅)보다 높으면 배관온도가 기준온도(t₆)보다 높을때 히터를 정지하고 타이머를 클리어하는 제5스텝으로 이루어져 배관온도 및 실외온도에 따라 히터가 동작되어 쾌적한 난방을 제공한다.In the present invention, the first step of stopping the heater and clearing the timer when the compressor is not in operation or during defrost operation, and determining whether the heater is in operation when the compressor is in operation and is not in defrost operation. a second step, a second clear the timer the pipe temperature is higher than the reference temperature (T ₁₎ when the step-heater is not driving on, and if low, a predetermined time (m min) has passed the reference temperature (t _2), the outside temperature after If the outside air temperature is lower than the reference temperature (t ₂ ) in the third step and the third step to compare with and the heater is operated only when the piping temperature is lower than the reference temperature (t ₄ ) and the outside air temperature is higher than the reference temperature (t ₂ ) When the pipe temperature is higher than the reference temperature t ₃ , the fourth step of operating the heater, and when the outside air temperature is lower than the reference temperature t ₅ during the heater operation in the second or fourth step, the pipe temperature is a reference value. Higher than temperature (t ₇ ) or ambient temperature When the temperature is higher than the t ₅ , the fifth step of stopping the heater and clearing the timer when the piping temperature is higher than the reference temperature t ₆ is performed according to the piping temperature and the outdoor temperature, thereby providing comfortable heating.

Claims

A first step of stopping the heater and clearing the timer when the compressor is not in operation or defrosting during heating, and a second step of determining whether the heater is in operation when the compressor is in operation and not in the defrosting operation, and When the heater is not operated in the second step, when the pipe temperature is higher than the reference temperature T ₁ , the timer is cleared. When the heater temperature is low, the third air temperature is compared with the reference temperature t ₂ after a predetermined time (m minutes). If the outside temperature is lower than the reference temperature (t ₂ ) in the step and the third step, the heater is operated only when the piping temperature is lower than the reference temperature (t ₄ ), and if the outside temperature is higher than the reference temperature (t ₂ ), the piping temperature is the reference temperature. The fourth step of operating the heater when the temperature is lower than the t ₃ , and if the outside air temperature is lower than the reference temperature t ₅ during the heater operation in the second or fourth step, the pipe temperature is the reference temperature (t ₇ ). when higher than the outside temperature, or is higher than the reference temperature (t ₅₎ Method heater controlling a cooling / heating air conditioner including a fifth step of stopping the heater when the pipe temperature is higher than the reference temperature (t _6), and clear the timer.

The heater of claim 1, wherein the reference temperature (t _1- t ₇ ) has a characteristic of t ₂ ≤ t ₅ , t ₁ ≤ t ₃ ≤ t ₄ ≤ t ₇ ≤ t ₆ Operation control method.
