Separate household heating measurement device of serial single-pipe connection type heating pipe network system and method

Abstract

The invention relates to a separate household heating measurement device of a serial single-pipe connection type heating pipe network system and a separate household heating measurement method. The device comprises a flow meter, a heat integral thermostatic valve, an M_BUS bus, an M_BUS data collector, a DTU (digital transmission unit) and a computer. In the method, heat of a separate household can be measured via measuring heat losses of a heat radiator on each riser, each heat integral thermostatic valve is used for measuring heat losses of the heat radiator connected behind the heat integral thermostatic valve, then the heat calculated by each heat integral thermostatic valve is collected by the M_BUS bus and a data control center, and the heat consumed by the household can be calculated. The layout of the original pipe network needs not to be changed, no punching through walls is needed, the disturbance to households is small, the cost is low, and the problem of separate household heating measurement and energy conservation can be solved with no needs for installation of a heater meter in each household.

Description

technical field [0001] The invention relates to household heat metering in an existing building, in particular to a household heat metering device and method for a single-pipe series heating pipe network system. Background technique [0002] According to preliminary statistics, there are about 1.2 billion square meters of old residential buildings in the north that can be renovated. If we consider the heat metering renovation of energy-saving buildings, the area to be renovated will reach 2 billion square meters. The project volume is very large and the amount of funds required is also large. Large, the energy-saving transformation of existing buildings can not only save a lot of energy, but also greatly increase the indoor temperature. But the real problem is that, on the one hand, the government's investment is insufficient, and on the other hand, the homeowners are unwilling to invest, which has caused many difficulties and slow progress in the renovation of various place...

Problems solved by technology

But the real problem is that, on the one hand, the government’s investment is insufficient, and on the other hand, the homeowners are unwilling to invest, which makes the renovation in various places face many difficulties and the progress is slow

Most of the old residential heating pipes in northern my country are single-pipe series-connected. If it is changed to charge by household heat metering, the pipe network needs to be changed to double-pipe parallel-connected. The transformation cost will greatly increase, disturb the residents, and the construction period will be long. Under the current situation, enterprises are required to launch products suitable for China's national conditions and effectively solve problems

[0003] Under the current status quo, if the transformation plan can be successful, the following conditions must be met: 1. The original pipe network structure should not be changed; 2. Household heat metering should be realized; 3. The transformation period should not be long and the transformation cost should not be high
