ENERGY MANAGING METHOD BY CONTROLLING TEMPERATURE DIFFERENCE BETWEEN PRIMARY COLD WATER AND RETURNING COLD WATER AND ENERGY MANAGING DEVICE FOR SAME

摘要

Save power water supply pump the present invention relates to a kind of method of energy management for building and cold water and returned at cold water of temperature mutual deviation by control, change the water supply pump of flow velocity, keep pleasant indoor environment and thermal management device and. The building energy consumption system data on heat resource equipment that the present invention is effectively worked by the energy consumption of the water supply pump adjusts the flow velocity of water supply pump, when the main cold water of the temperature difference and Returning water are lower than predetermined temperature or the water supply pump and have excessive rate; And optimize energy-saving effect, by periodically or seasonally monitoring the main cold water of the temperature difference and returning to the energy management system of cold water based service condition, the water supply pump for changing flow velocity, obtains safety coefficient as heat source facility and pleasant indoor environment user to meet condition. ;The 2014 of copyright KIPO submissions;[Reference numerals] (11) block water pump; (12) cooling tower; (13) soil water coil; (14) refrigeration machine; (AA) Coolants return temperature; (BB) Coolants supplying temperature; (CC) Coolants return flux; (DD) Coolants pump; (EE) soil water supplying temperature; (FF) soil water return temperature; (GG) soil water return flux; (HH) air supply fan; Region (II) air-conditioning
