Water ga(u)ge 7 is above-mentioned first flow sensor.
Oil flowmeter 8 is above-mentioned second flow sensor.
Hot water output device 2, the hot water outlet of one end connecting plate type heat exchanger 4, the other end connects water-circulating pump 1, at water
Equipped with water ga(u)ge 7 before circulating pump 1, water ga(u)ge 7 is for detecting the size of flow and the working condition in water route.Work as water route
When occurring abnormal, signal will be fed back to automatic control equipment and supervision and management center by water ga(u)ge 7, and automatic control equipment can be according to current
Situation is made correct action and reports to the police.Automatic water-replenishing device, temperature-detecting device is had in hot water output device 2.Work as water level
Time not enough, automatic water-replenishing device can carry out moisturizing automatically, and temperature-detecting device is for detecting the temperature of hot water.
Plate type heat exchanger 4 is the high-performance heat exchanger being formed by stacking by many plates.Plate type heat exchanger 4 one has 4 ports,
First end connects oil circulating pump 5, and the second end connects Oil Tank 6, three-terminal link water-circulating pump 1, and the 4th end connects hot water output dress
Put 2 and fan coil 3.Wherein, the first end and the second end are positioned at the side of plate type heat exchanger 4, and the 3rd end and the 4th end are positioned at plate
The opposite side of formula heat exchanger 4.Deep fat flows to heat-exchangers of the plate type, and the cold water then flow to opposite side carries out heat exchange.From
Plate type heat exchanger cold oil out is recycled in Oil Tank go to absorb heat.And just absorbed the hot water of heat in deep fat and followed by water
Ring pump is recycled to waste-heat recovery device release heat, and the recirculation of cold water after heat release to plate type heat exchanger absorbs heat.
Import and export at plate type heat exchanger is equipped with Pressure gauge and temperature sensor, Pressure gauge and temperature sensor and is used for
The working condition of detection oil circuit and running status.Connecting before oil circulating pump 5 and have oil flowmeter 8, oil flowmeter connects Oil Tank 6
Oil-out, oil flowmeter is for checking the oil size of flow and the duty of equipment.
When the sensor on plate type heat exchanger detects that temperature exceeds reference temperature range, oil circulating pump and water-circulating pump
All can carry out raising frequency or frequency reducing work, it is achieved energy-saving and cost-reducing.
When flow out plate type heat exchanger water temperature over-high or flow out plate type heat exchanger high oil temperature time, illustrate participation heat exchange
The water yield very little, heat absorption capacity is not enough, and now, water-circulating pump will carry out raising frequency work, to strengthen the water yield participating in circulation.As
Fruit adds flood circulating load and is still unable to reach design temperature, and control system carries out raising frequency work by instructing oil circulating pump simultaneously, adds
The circulating load of big oil, improves the efficiency of heat exchange.
When the water temperature flowing out plate type heat exchanger is too low or the oil temperature of outflow plate type heat exchanger is too low, illustrate to participate in heat exchange
The water yield too many, waste heat absorption resource, at this point it is possible to water-circulating pump is carried out frequency reducing operation, to reduce the water yield participating in circulation,
To save the energy.
Above-mentioned fan-coil device 3, is connected in parallel on hot water output device, is equipped with valve on branch line, needs
Hot water end valve door (above-mentioned first valve) it is switched on, by the cool water heating in heat feed-tank, prepared hot water during hot water preparing
For daily use；Needing to be switched on fan coil pipe valve (above-mentioned second valve) during heating, heat is and coil pipe
Realizing the exchange of heat, hot blast is blown to room by blower fan, for heating rooms；If open two valves simultaneously, produce heat
Can also warm oneself while water.
Above-mentioned water-circulating pump 1, what water-circulating pump in the present system used is all the redundancy of N+1, uses a flood to follow
The heat radiation circulation of ring pump load all liquid refrigerator.In CN105258332A patent, the redundancy of liquid cooling heat radiation system water-circulating pump is
2N, the water inlet of each plate type heat exchanger is with two little water-circulating pumps, the most not only wastes space, also add into
This, reduce reliability.Present water-circulating pump is by concentrated controling management, only need to install additional individual before each plate type heat exchanger
Water regulating valve, the aperture of electromagnetic valve is controlled by the feedback signal of control centre, and valve is board-like by collecting in automatic control equipment
The temperature of heat exchanger water inlet pipe and water outlet pipe is adjusted control.When automatic control equipment calculates, and present flow rate meets plate type heat exchanger
During radiating requirements, then it is not required to carry out the increase of valve opening；If present flow rate cannot meet the radiating requirements of plate type heat exchanger
Time, then need to increase valve opening, strengthen flow of inlet water.Simultaneously equipped with y-type filter before the entrance of water-circulating pump, its effect was
Impurity in drainage.
Above-mentioned oil circulating pump 5, what oil circulating pump in the present system used is all the redundancy of N+1, it is achieved a big oil follows
The circulation of oil in the whole Oil Tank of ring pump load.In CN105258332A patent, the redundancy of liquid cooling heat radiation system oil circulating pump is
2N, the oil-in at each plate type heat exchanger is equipped with two little oil circulating pumps, the most not only wastes space, also add into
This, reduce reliability.Present oil circulating pump is all by concentrated controling management, and the oil-in at each Oil Tank is equipped with oil
Regulation valve, carries out Flow-rate adjustment distribution according to the temperature that each Oil Tank feeds back.Arrived by the returning-oil temperature sensor feedback in cabinet
The information of automatic control equipment carries out Flow-rate adjustment, and when temperature is higher than design temperature, the aperture of regulation valve increases, and strengthens the circulation of oil
Amount；When temperature is less than setting value, the aperture of regulation valve reduces.Simultaneously equipped with y-type filter before the entrance of oil circulating pump, it is made
With the filtration for impurity.
Ye Leng data center residual neat recovering system do not have cooling tower device, compressor, fan, cold-producing medium.Water follows simultaneously
Ring pump and oil circulating pump have the most all carried out concentrated controling management, use the redundant mode of N+1.Therefore native system is without compression
Machine, the pollution of fan noise, improve space availability ratio simultaneously and decrease input cost, improve the efficiency of heat transmission,
Improve the reliability of system, reduce the loss of the energy.
And Ye Leng data center residual neat recovering system uses conduction oil and directly exchanges with server heat, then pass through
Plate type heat exchanger transfers heat to waste-heat recovery device, and directly the heat exchange pattern of contact substantially increases heat exchange efficiency.Work
Time only have the participation of conduction oil, oil circulating pump, water-circulating pump, be different from patent CN103249284A must have consumable accessory pressure
Contracting machine and consumable accessory fan, pump, cold-producing medium.
