Background technology
In water resource heat pump water system, water source refers to available surface water, underground water in air-conditioning system, not the recirculated water that utilizes the equipment such as cooling tower auxiliary cooling (or heating), user refers to the little user of distributing, each user's Independent source pump, open independent control, a project for example generally has tens, to a hundreds of user, senior villa cluster.
The common way of existing water resource heat pump water system has two kinds.Way one, many fixed water pump water supply systems frequently, flow control valve is established in each heat pump main frame import, electric butterfly valve interlocking main machine on off control is established in water outlet, and exit of pump pipeline section is established relief valve and is controlled, and utilizes the number of units of the pressure control judgement water pump of exit of pump pipeline section to drop into.Way two, many water pump water supply systems, water pump is done VFC, flow control valve is established in each heat pump main frame import, electric butterfly valve interlocking main machine on off control is established in water outlet, exit of pump pipeline section is established relief valve and is controlled, and utilizes the pressure of exit of pump pipeline section to control number of units input or the VFC that judges water pump.
Two kinds of way subject matters are that operating cost is higher and operating condition is unstable.Way one, when sub-load, when user's request flow is not just in time the integral multiple of separate unit pump capacity; there is earial drainage; ductwork pressure in service, with the fluctuation of user's start and stop unit, causes the cooling operating mode of the unit moving unstable, even occurs autostop problem.Way two has just been improved way one; performance characteristics due to low profile thermal pump assembly; each user's flow, resistance do not allow to be less than specified demand; flow diminishes while not mating, and only has the resistance of pipe network changing, and the scope of frequency conversion is very little; controlling bad meeting causes the user who is moving to shut down; and the earial drainage of severe jamming exit of pump is controlled, in actual items, finally not frequency conversion of VFC.
