Description

A kind of central heating temperature self-adaptation control device

Technical field

The utility model relates to a kind of single-chip microcomputer central heating energy-saving controller, a kind of specifically central heating temperature self-adaptation control device.

Background technology

Along with measuring technique, monitoring technique, automatic technology and development of computer, the central heating of China is entering the Rapid development stage of intelligent automation control.In central heating system, can be divided into thermal source, two relatively independent systems of heat supply network to heating system, thermal source comprises the public part of boiler and boiler room, heat supply network comprises once net, heat exchange station and secondary net.

Control by thermal source, can adjust the load of boiler to a certain extent, make the operation of boiler more economical efficient, the more equal perseverance of heat supply is reasonable, thereby reach energy-conservation purpose, with respect to the control of thermal source, the control of heat supply network mainly is the horizontal thermal misadjustment of eliminating between each terminal use, input amount according to load prediction, environment temperature, user indoor temperature, secondary net return water temperature are regulated pipe network realizes balanced heating.But the control of heat supply network at present and transform be basically rely on environment temperature and once the net return water temperature once net and heat exchange station are carried out reducing energy consumption, there is following problem t in existed system at present

(1) be that net is once carried out equilibrium control basically, the main reference environment temperature is carried out heating load and is regulated.Do not consider the automation control section of secondary net.

(2) not a complete dynamic unsteady flow amount heating system, complete dynamic variable flow system is the trend of present international heat supply and environment friendly system development, developed countries basically from the thermal source to the heat supply network, the user indoor temperature measurement formed the dynamical system of an integral body, make hot user's indoor temperature more reasonable comfortable, can save the energy greatly again simultaneously.

(3) special heating at enterprises and institutions nights does not have regulatory mechanism at part, because the nobody basically after 11 at night of part enterprises and institutions if can carry out meticulous control, can reduce the heating load of this part unit in this case, saves heating load.

(4) present system's main reference environment temperature and supply and return water temperature, not with reference to user indoor temperature, therefore to the not enough exact science of grasp of heat supply scheme and heat supply rule, if add typical user's indoor temperature measurement point, balanced heating can rationally be regulated whole heating system more accurately.

The purpose of heat supply is to make hot user's indoor temperature reach reasonable, comfortable temperature value, be overheated or cold this purpose that all departed from, overheated meeting causes the energy to waste in a large number, has strengthened the cost of heat supply department; Cross coldly, the user is dissatisfied, has strengthened the work difficulty of heat supply department, no matter the difficulty of heat supply department actual operation takes place all can cause the sort of situation.

Summary of the invention

Technical assignment of the present utility model is to overcome above-mentioned shortcoming, and a kind of central heating temperature self-adaptation control device of simple in structure, reasonable in design, easy to use, safe, good energy-conserving effect is provided.

The technical solution of the utility model realizes in the following manner: its structure is by single-chip microcomputer, heat exchanger, motor-driven valve and sensor are formed, wherein, heat exchanger is provided with the high-temperature steam inlet tube, the Low Temperature Steam outlet, the backwater inlet tube, the hot water outlet pipe, be positioned at the high-temperature steam inlet tube and be provided with motor-driven valve, be positioned on hot water outlet pipe and the backwater inlet tube and be respectively arranged with temperature sensor, motor-driven valve, temperature sensor is connected with single-chip microcomputer by data wire, be positioned on the single-chip data interface and also be connected to environment temperature sensor respectively by data wire, ambient humidity sensor and air velocity transducer, the single-chip microcomputer panel is provided with the wind speed selector switch, the humidity selector switch, manual automatic selector switch and touch display screen.

Two cover coil heat exchangers are set in the heat exchanger, are connected with high-temperature steam inlet tube, Low Temperature Steam outlet with hot water outlet pipe, backwater inlet tube respectively and are connected.

Adopt the beneficial effect in technology of the present utility model garage to be, simple in structure, be easy to control, under the situation that guarantees community's heating, energy savings is put and ended to waste, and has good value for applications.
