Abstract

(목적) 종래 내장상품의 고선도 관리를 실시하는 이른바 2증발기형 진열에서는 제상시의 상품온도 상승을 방지하기 위해 복잡한 기능부품을 사용하고 있고, 원가가 높고, 고장도 많고 유지도 어려운 결점이 있다. 그러므로 통상의 기능부품을 사용하는 제상 제어방법으로 상기 결점을 해소한다.(Purpose) In the so-called two-evaporator type display, which manages the high level of the conventional interior goods, complicated functional parts are used to prevent the rise of the product temperature during defrosting, and the cost is high, there are many failures, and it is difficult to maintain. . Therefore, this deficiency is eliminated by the defrost control method using a normal functional part.

(구성) 상시의 냉각 모우드(01)에서는 주 증발기를 냉각 운전시키고, 주 증발기의 제상 모우드(02)에서는 주 증발기의 냉각 정지후 보조 증발기의 냉각을 개시하고, 그후 지연시간(T1d)의 경과후에 주 제상히터(7)을 온한다. 또한, 상기 주 증발기의 제상후의 이중 냉각 모우드(03)에서는 보조 증발기의 냉각운전을 단속한 상태로 주 증발기 냉매를 주입시키고 이 냉매공급 개시후 지연시간(T2d)가 경과된 다음 주 팬(M1)을 회전시켜 이중 냉각 풀다운을 실시한다.(Configuration) In the usual cooling mode (01), the main evaporator is cooled and operated, and in the defrost mode (02) of the main evaporator, cooling of the auxiliary evaporator is started after the cooling stop of the main evaporator, and then after the delay time (T1d) has elapsed. Turn on the main defrost heater (7). In addition, in the dual cooling mode 03 after defrosting the main evaporator, the main evaporator refrigerant is injected while the cooling operation of the auxiliary evaporator is interrupted, and after the delay time T2d has elapsed, the main fan M1 has passed. Rotate to perform dual cooling pull down.
