Description

Automatic temperature control equipment based on the metering of household heating heat

Technical field

The utility model relates to the automatic temperature control equipment based on the metering of household heating heat, specifically relate to a kind of heating terminal temperature auto-control equipment, and it combines calorimetric hot function of measuring.

Background technology

China's heating system and heating cost collecting mode exist problems such as waste resource, charge injustice at present, and the development of the terminal temperature regulative mode in heating system is not comprehensive, that manual adjustment device exists is coarse as reconciling, easily produce drawbacks such as thermal deviation and mechanical damage, and Radiator Thermostatic Controller also can not reach accurate temperature controlling and temperature automatically controlled requirement because of the factor of its structure and medium.By Zhao Xiaojin, Dong Jianyuan, Yang Shale is in power-saving technology 2009,27 (2): that delivers on the 164-180 page or leaf is entitled as in " design of centralized heating and energy conservation control terminal ", proposed to realize the centralized heating and energy conservation control terminal design of temperature control by the valve switch of note control, but can't avoid human intervention, can not reach temperature automatically controlled purpose.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides

For achieving the above object, now adopt following technical scheme:

Based on the automatic temperature control equipment of household heating heat metering, it comprises radiator, and radiator is connected with outlet conduit with inlet channel respectively, is respectively equipped with attemperating unit on inlet channel and outlet conduit.

Described attemperating unit comprises single-chip microcomputer, single-chip microcomputer respectively with flowmeter, water temperature detection module I, water temperature detection module II, the room temperature detection module is connected with electrically operated valve; Described flowmeter, water temperature detection module I and electrically operated valve are located on the inlet channel successively; Water temperature detection module II is located on the outlet conduit.

Described water temperature detection module I and water temperature detection module II are thermal resistance.

Described room temperature detection module is a temperature sensor, and described temperature sensor is installed on the indoor wall.

Described single-chip microcomputer also is connected with input equipment with display module respectively.

Described input equipment is a keyboard.

The beneficial effects of the utility model: the utility model provides a kind of heating system terminal automatic temp controller, it can realize the auto-control of user to indoor temperature, reduce human intervention, and in conjunction with calorimeter function realization branch family heat metering and temperature automatically controlled integrated, can also allow heating system under different mode, work to the demand that heats according to the user, reduce unnecessary heat exhaustion.

Fig. 2 circuit theory diagrams of the present utility model;

Wherein, 1 inlet channel, 2 flowmeters, 3 thermal resistance I, 4 single-chip microcomputers, 5 electrically operated valves, 6 radiators, 7 thermal resistance II, 8 temperature sensors, 9 outlet conduits, 10 keyboards, 11LCD display, 12 drive circuits.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a preferred embodiment of the present utility model, and as shown in Figure 1, this equipment body comprises radiator 6, and radiator 6 is connected with outlet conduit with inlet channel respectively; Single-chip microcomputer 4 and electrically operated valve 5 are installed on user's hot duct inlet channel 1, and single-chip microcomputer 4 is connected with electrically operated valve 5; Thermal resistance I 3 is installed on the inlet channel 1, the heating inflow temperature of resident family is changed into the signal of telecommunication send single-chip microcomputer 4 to; Thermal resistance II7 is installed on the outlet conduit 9, leaving water temperature is changed into the signal of telecommunication send single-chip microcomputer 4 to; The flowmeter 2 that is installed on the inlet channel 1 inputs to single-chip microcomputer 4 with current water supply flow, single-chip microcomputer 4 calculates Inlet and outlet water temperature, flow of inlet water and current elapsed time the heat of user's period internal consumption by plug-in, and show by display 11, realize calorimetric function.

As shown in Figure 2, single-chip microcomputer 4 respectively with keyboard 10, LCD display 11, temperature sensor 8 connects, single-chip microcomputer 4 rotates electrically operated valve 5 by drive circuit 12, realizes the aperture of electrically operated valve 5 with this.The user can be by keyboard 10 to the required indoor temperature of single-chip microcomputer 4 inputs, single-chip microcomputer 4 can compare being installed in current indoor temperature and the user's design temperature that indoor temperature sensor 8 records at set intervals, according to the aperture of comparable situation electrically operated valve 5, regulate indoor temperature.Promptly when indoor temperature was higher than design temperature, single-chip microcomputer 4 can rotate the regular hour by control electrically operated valve 5, valve opening is reduced, thereby reduce to manage interior flow; When indoor temperature was lower than design temperature, single-chip microcomputer 4 can rotate the regular hours by control electrically operated valves 5, increased valve opening, thereby increased flow in the pipe, through repeatedly among a small circle adjusting, made indoor temperature finally reach the satisfactory value that the user sets like this.

In addition, this equipment has two kinds of operational modes, in the room nobody the time be made as low temperature mode---heating installation is closed substantially; When living, someone is made as the heating pattern---and keep the certain aperture of valve, keep ambient-temp-stable.The user can set the time that two kinds of patterns are changed by keyboard 10 inputs according to self needs, to reach energy-conservation and purpose temperature control.
