System is also under low load condition and runs during energy supply.Such as Fig. 1, traditional Regional Energy secondary pumping system is divided into hot and cold water system
The conveying of standby and hot and cold water uses two parts, forms Cooling and Heat Source side ring road and load side loop.Traditional Regional Energy secondary pump
System Cooling and Heat Source side ring route cold and hot source device 1（Boiler, heat pump, handpiece Water Chilling Units etc.）, once pump 2, for return pipe 3 and balance pipe
4 compositions, balance pipe 4 are generally arranged at the preparation for being responsible for hot and cold water close to cold and hot source；Load side loop is by balance pipe 4, outdoor
Transmission pipeline network 5, secondary pump 6, indoor transmission pipeline network 7, end-equipment 8 and electric two-way valve 9 form, and being responsible for hot and cold water conveying makes
With.The method of operation of traditional area energy source secondary pumping system is:Once pump 2 constant flows, 6 variable-flow operation of secondary pump.Secondary pump 6
Variable-flow is then to supply return pipe pressure difference according to load side（Pressure difference is influenced by the switch of end-equipment electric two-way valve 9）Adjust secondary
The rotating speed of pump 6, so as to fulfill energy saving.
And operate above mode and had some limitations when system low load condition is run：Although secondary pump 6 can
Frequency conversion is realized according to the workload demand of end, but Load Regulation is realized using frequency conversion, adjustable range is limited, a small amount of for user
When in use, secondary pump 6 is run still in the small temperature difference of big flow, and pump energy consumption is of a relatively high, and pump efficiency is relatively low, causes energy
Source serious waste.
Utility model content
The purpose of this utility model is to provide the new region energy that a kind of first pump system and secondary pumping system automatically switch
Source water system so that system is accomplished energy-efficient when being in low load condition operation.
Technical solution provided by the utility model is：

Secondary pump, indoor transmission pipeline network, end-equipment and electric two-way valve, set electric control valve on the balance pipe of cold and hot source, at the same time
Imported and exported in secondary pump and bypass pipe is set, electric control valve is set on bypass pipe, temperature is set on the feed pipe of outdoor transmission pipeline network
Spend sensor one and pressure sensor one, set temperature sensor two, pressure sensor two and flowmeter on return pipe.
The utility model makes optimization design based on conventional Regional Energy distribution secondary pumping system, in the flat of cold and hot source
Electric control valve is set on weighing apparatus pipe, load side secondary pump inlet and outlet set bypass pipe, set on bypass pipe electric control valve and
In outdoor transmission pipeline network for adding corresponding data monitoring device on return pipe.
The utility model judges whether system is in underload by monitoring outdoor transmission pipeline network supply and return water temperature and flow
Run under state, when being run in low load condition, system can be realized by accordingly controlling water pump and electric control valve
Automatic switchover of the secondary pumping system to first pump system, when load is larger, then switches to secondary pumping system.The utility model leads to
Cross and system is improved and optimizated, preferably realize the automatic switchover of first pump system and secondary pumping system, improve water pump
Operational efficiency, reduces the conveying energy consumption of pipe network, so as to improve the comprehensive energy efficiency of system.
