Energy-saving temperature monitoring method and system for evaporator

The invention discloses an energy-saving temperature monitoring method and system for an evaporator, and belongs to the field of building heating, and the method comprises the following steps: interactively obtaining target design parameters of a target evaporator, and obtaining a target twin model; running temperature change analysis is carried out, a sensor arrangement array is obtained, RTD sensor arrangement is carried out, a target monitoring array is obtained, temperature change data calling is carried out, K pieces of dynamic temperature change data are obtained and synchronized to a temperature change abnormity identification sub-network, a temperature change abnormity identification result is obtained, a heat supply switching instruction is generated, and heat supply system switching of a target place is carried out. The technical problems that in the prior art, due to the fact that the evaporator fault is indirectly recognized according to the physical state of the refrigerant output by the evaporat
