Zusammenfassung: | The present invention relates to a heat storage type heating and cooling system and, more specifically, to a heat storage type heating and cooling system for a smart farm using hydrothermal energy, which is configured to: if there is no load difference to acquire thermal balance when cooling and heating are performed at the same time, circulate cold water in a cold water heat storage tank or hot water in a hot water heat storage tank by a heat pump to perform cold storage and heat storage operation; if the thermal balance is lost due to the load difference when cooling and heating are performed at the same time, during cold storage, circulate the cold water in the cold water heat storage tank by the heat pump, simultaneously circulate the hot water in the hot water heat storage tank by the heat pump according to a load amount, store part of the cold water and the hot water and then discharge the hot water, discharged from the heat pump, as water heat by allowing a heat exchanger to exchange heat with an external heat source; and during heat storage, circulate the hot water in the hot water heat storage tank by the heat pump, simultaneously circulate the cold water in the cold water heat storage tank by heat pump according to a load amount, store part of the cold water and the hot water and then discharge the cold water, discharged from the heat pump, as water heat by allowing a heat exchanger to exchange heat with an external heat source, thereby enabling stable operation by controlling heat storage and cold storage according to the heat balance.
본 발명은 축열식 냉난방 시스템에 관한 것으로서, 상세하게는 냉방과 난방을 동시 수행시 부하 차이가 없어 열 밸런스가 평형을 이루게 되면, 냉수 축열조의 냉수 또는 온수 축열조의 온수를 히트펌프로 순환시켜 축냉 및 축열 운전하고, 냉방과 난방을 동시 수행시 부하 차이로 인해 열 밸런스가 불평형을 이루게 되면, 축냉시 냉수 축열조의 냉수를 히트펌프로 순환시킴과 동시에 부하량에 따라 온수 축열조의 온수를 히트펌프로 순환시켜 일부 저장한 다음 히트펌프에서 배출되는 온수를 열교환기를 통해 외부 열원과 열교환을 통해 수열로 배출하고, 축열시 온수 축열조의 온수를 히트펌프로 순환시킴과 동시에 부하량에 따라 냉수 축열조의 냉수를 히트펌프로 순환시켜 일부 저장한 다음 히트펌프에서 배출되는 냉수를 열교환기를 통해 외부 열원과 열교환을 통해 수열로 배출하여 열 밸런스에 따라 축열과 축냉을 제어하도록 함으로써 안정적 운전이 가능하도록 하는 수열 에너지를 이용한 스마트 팜용 축열식 냉난방 시스템에 관한 것이다. |
