Method for simultaneously implementing heat regulation and heat measurement

Abstract

The invention relates to a method that can accomplish heat adjusting and meter at one time and the equipment, belonging to HVAC area. Said method is that calorimeter is set at the heat inlet of each building to calculate the total heat, which is seen as heat supply charge basis of the building; on-off control valve for room-temperature is set on each said branch pipe of inlet and user can set room-temperature arbitrarily in certain range by the room-temperature controller or put room-temperature controller at any position according to the demand; said room-temperature measures the room temperature and transmits the room-temperature signal measured and set by user to on-off control valve for room-temperature wirelessly and the opening time of valve is calculated and stored by control strategy for building heat characteristic in the on-off control valve so as to adjust on-off control valve for room-temperature with the purpose of controlling room-temperature; and then according to accumulative opening time of on-off control valve for room-temperature and indoor area heat supply for user is allocated. The invention can realize heat adjusting and meter at one time.

Description

technical field [0001] The invention relates to a method and a device for simultaneously realizing heat regulation and heat metering, and belongs to the field of heating, ventilating and air conditioning. Background technique [0002] At present, the heat metering methods tried in our country are basically divided into two categories: one is to directly measure heat by household, that is, install a heat meter at each user's heat inlet to measure the user's heat consumption, and install a temperature control valve at the radiator to adjust; The other is to install a total heat meter at the thermal entrance of the building to measure the total heat of the building, and then carry out heat distribution through a certain method. There are two main types according to the different distribution methods. One is to install a heat distribution meter at the radiator. Each household uses heat for heat allocation, and the other is to install a thermometer indoors to accumulate the room ...

AI Technical Summary

Problems solved by technology

But there are still the following problems: (A) The household metering and charging method promoted for energy saving leads to an increase in the installation of indoor radiators and an increase in the insulation requirements for household partition walls and floors

(B) Implement heat metering correction, comprehensive heat price, and two-step charging. When the correction coefficient is too large and the weight of the area charging part is too large, the charging reform will hardly play its original role, and it will cost a lot The complex charging system established does not achieve the purpose of promoting energy saving in heating

[0005] (2) The evaporative heat allocation method and the room temperature cumulative heat allocation method cannot solve the problem of user window opening

[0008] Mainly include: 1) The heat meter method of direct household measurement of heat has problems such as mechanical meters not suitable for the water quality of the heating network, serious blockage and damage, and high failure rate. Ultrasonic household meters are expensive and exceed the economic affordability of users

The temperature control valve also used for adjustment is not suitable for water quality, and its reliability is low; 2) The metering accuracy of the apportioned heat distribution meter is greatly affected by the installation quality, and it is only suitable for certain types of radiators, while domestic radiators There are many kinds of devices, which cannot be universally applied, nor are they suitable for other systems such as floor heating and roof radiation; If used alone in a series system, it will cause thermal imbalance

[0009] (4) The measurement and adjustment are completed by different equipment, and the cost is high

[0010] The measurement and adjustment of the current measurement method are completed by two different links and different equipment separately. It is necessary to install a temperature control valve, a household heat meter or a heat distribution meter, etc., and the investment is relatively large.
