Abstract
This article mainly discussed the hot distribution list characteristic, the divergence coefficient influence as well as the related design variable choice, and proposed some design new concept. After realizing the hot measurement charge, the heating system increased the controllability, each radiator and the customer set-up have controlled the valve warm. The user may according to own need, momentarily adjust the heat dissipating arrangement the heat dissipating capacity. The heating system's basic situation has had the change, therefore deals with the original heating design variable and the design method carries on the revision, after is suitable the hot measurement charge new situation. To each kind of hot metering device which present domestic, outside uses carries on analyzes and compares, pointed out that under our country central heat supply's existing condition, the electronic formula hot distribution list is one kind of comparison use hot gauge table, Is surveys the temperature and the corresponding time electronic installation, its hot value is the radiator surface survey characteristic temperature to the time integral approximate value perhaps the radiator surface temperature and the indoor temperature differential value to the time integral, is calculates each household radiator basis is also carries on calculates each household hot expense the basis. The electronic formula hot distribution list according to its survey principle as well as probe head's quantity's difference, may divide into two probe head type electronic formula hot distribution list and the multi-probe head type electronic formula hot distribution list. Take ultra bottom power loss monolithic integrated circuit MSP430F149 as the core, studies one section to be possible to realize the reading to be simple, the maintenance work load small, is advantageous for the networking long-distance to copy the table. The central heat supply charges the heating expense according to the reality with thermal how many to the user is reasonable, is also the energy conservation important measure.
