<p>PURPOSE: An energy-saving cold storage system with separate cold storage/cold release pumps is provided to prevent unnecessary power consumption by actuating only the cold release pump in a cold release mode. CONSTITUTION: An energy-saving cold storage system comprises a hot storage tank(110), a freezer(120), a heat exchanger(130), a closed cold storage circuit(140), a cold storage pump(150), a closed cold release circuit(160), a cold release pump(170), and a controller(180). The hot storage tank stores cold using midnight electricity. The freezer comprises a cooling tower and a cooling water pump to form a closed freezing circuit. The heat exchanger comprises a temperature sensor for measuring the temperature of cooling water and lowers the temperature of the cooling water through heat exchange with brine. The closed cold storage circuit connects the hot storage tank and the freezer. The cold storage pump is installed in the closed cold storage circuit to circulate brine. The closed cold release circuit connects the hot storage tank and the heat exchanger. The cold release pump is installed in the closed cold release circuit to circulate brine.</p> |
