Abstract

The new scheme controls timing thermostat and relevant control valve in control unit divided from heating system according to each door or room so as to adjust and manage temperature in control unit. The thermostat is composed of CPU, control circuit, timing circuit, temperature sensor, and interface circuit of output signal. The invention measures heat quantity by using cumulant of opening quantity and time of valve instead of using heat meter to measure evaporation capacity and flux. Thus, thermostat capable of setting up temperature in advance is installed at each door (control unit) to control turning on/off inlet valve of heat supply and control cumulative opening time. Family in each door can know own consumed heat quantity and expense from display on thermostat. The invention can control sub door within control of valve, or all doors networked so as to control entire heating system. The invention distributes heat quantities, manages charges, and controls temperature.

Description

The technical method of digital control heat supply managing and metering

Technical field

The invention belongs to a kind of heating control and management and metering distribution Fare Collection System, it specifically is the unlatching cumulative time of a kind of metering each family (control module) inner control valve, fair more, measuring reasonably to each user with heat, and further reach networking to each household (control module) temperature controller, realize control and management to whole heating system.

Technical background

Because the singularity of heating metering, the hot metered scheme that extensively adopts can be divided into following four kinds in the world:

Option A: a building hotlist.The hear rate in whole building is by a hotlist metering that is installed in hot porch, and the heat expense of whole building is charged according to the hear rate of hotlist metering, then, shares to each resident family according to floor area of building.

Option b: Heat distribution meter.Except entire building being carried out " metering " according to option A, the heat dissipation capacity of each heating radiator of each household is carried out " metering " with vaporation-type or electronic type Heat distribution meter, the heat of entire building heat consumption expense (comprising the charge expenditure) will be partly according to each living space, partly share to each household according to the Heat distribution meter reading.

Scheme C: flow of hot water scale.By hot water gauge hot water flow in each resident family's heating radiator is measured, the heat expense (by option A) of entire building is shared according to the hot water flow of each household.This scheme meaning requires the supply water temperature identical (actual impossible) of a building interior each household heat inlet.

Scheme D: family hotlist.The heat consumption of each resident family measures with hotlist by a family, just the miniaturization of a building hotlist (option A).The family can be used for sharing heat expense (option b, C) with hotlist also can directly calculate hot expense.

More than these metering methods have following defective, option A is unfavorable for that too simply resident family to temperature controlling, does not almost have energy-saving benefit, heating charging is the way of " big-pot " still.Also there are the maintenance cost height in B, C, D scheme, disturb residents, manageability and water quality had problem on the technical and expense such as requirement not, particularly the user to use heater unit to take place when unusual uncontrollable, use the behavior of heating installation to find and to handle then and there to stealing.To the not manageability and the control of behavior of the expense of being in arrears with, the heat supply water temperature is not reached requirement lack restriction way and measure, it is opaque and timely to charge, and resident family can't in time regulate and control and not reach temperature is energy-conservation comfortable purpose etc.

Summary of the invention

The invention discloses a kind of technology new departure with digital control heat supply managing and metering, this scheme is by the interior timing temperature controller of control module one by one to being divided into by family or chamber (multicell) in the heating system, control with the by-pass valve control of correspondence, thereby the temperature in the unit is regulated and control and managed.Above-mentioned timing temperature controller is by microprocessor CPU and control circuit, timing circuit, temperature sensor, compositions such as interface circuit of output signal.Timing temperature controller in each control module is the unlatching gear of by-pass valve control at any time, and each is opened gear, opening time carry out cumulative data, with the foundation of cumulative data as charge.This scheme is the scalable temperature, can carry out heat metering again and distribute charge, can realize that again remote control and regulation manages whole heating system.The present invention has changed the past and has distributed the pattern of heat by the family with hotlist metering and metering evaporation capacity, metered flow, replace valve opening amount and open-interval semi-invariant and carry out the method that the heat metering distributes, it is the temperature controller that each household (control module) is installed a predeterminable temperature, the unlatching (amount of opening an account) of control heat supply inlet valve, the accumulative total timing makes each household to understand own consumed heat quantity and expense by the demonstration of temperature controller during unlatching.Can reach again simultaneously adjustment and control are carried out in the branch family (control module) in the valve control; Further reach the networking of all users' (control module) temperature controller, thereby whole heating system is carried out monitoring management, each household (control module) is measured distribute and toll administration; And, guarantee that supply water temperature reaches minimum requirements by monitoring constantly to supply water temperature.

Purpose of the present invention has realized the justice of heating metering, reasonable, transparent, convenient, economic distribution, simultaneously reached the user again to indoor temperature adjusting, networking back heating company, infrastructure management company and user can carry out two-way control and management to heating quality, from now on reducing energy consumption is laid the foundation, set up the platform of expanding.

The heat metering charge, prerequisite is a household metering, purpose is to the adjustable energy savings again of room temperature.Purpose of the present invention has realized the justice, reasonable, transparent, convenient, economic of heating metering.Because whether it only opens and the single signal of open-interval with metering, transmit these signals when only taking, just provide possibility for whole heating system networking dynamic management running.Its installation is not sought the restriction of net system to old dwelling house, and each household, every chamber, every group of heating radiator all can be used as a control module and regulate and measure distribution.To newly-built dwelling house and build it and overcome the family especially with many technical matterss that hotlist quality cost and water quality cause, make the whole timing temperature controller control of user installation one cover house reasonable more economically.Calculating formula is as follows:

Q: sub-district (Lou Dong) always uses heat;

A _n: the building sides of the interior each household in sub-district (Lou Dong) (chamber);

t _n: the valve opening cumulative time of the interior each household in sub-district (Lou Dong) (chamber);

q _n: the hot sendout at (Lou Dong) n family, sub-district (chamber);

q_{n} = Q \times \frac{A_{n} \times t_{n}}{Σ A_{i} \times t_{i}}
