Two grades of net water return pipelines between end, the two grades of net supply channels being connected between node b and heat user end, it is connected to node a
And mixed water pipe between node b, described mixed water pipe is provided with manual modulation valve.
This utility model connects owing to using mixed water when radiant floor heating system thermal substation heat-exchangers of the plate type type selecting
Mode so that heat-exchangers of the plate type is imported and exported the temperature difference and is increased to 20 DEG C by original 10 DEG C, which reduces and flows through heat exchanger
Rate-of flow so that heat-exchangers of the plate type area reduction, and the thermal substation heat-exchangers of the plate type import and export mixed sailor of increase bypass is dynamic
Regulation valve, has simple in construction, the advantage such as cost-effective, reliable.
Accompanying drawing illustrates:
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is this utility model one-level net and two grades of net temperature and flow distribution schematic diagram.
Detailed description of the invention
Shown in accompanying drawing 1: this heating system includes heat-exchangers of the plate type 1 and heat user end 2, is connected to heat-exchangers of the plate type
The one-level net supply channel 3 of 1 one end and one-level net water return pipeline 4, be connected to two grades of screen plate heat of heat-exchangers of the plate type 1 other end
Exchanger inlet ductwork 5 and two grades of screen plate heat exchanger outlet pipelines 6, two grades be connected between node a and heat user end 2
Net water return pipeline 9, the two grades of net supply channels 10 being connected between node b and heat user end 2, be connected to node a and node b it
Between mixed water pipe 7, described mixed water pipe 7 is provided with manual modulation valve 8.
This utility model calculates thermic load according to area of heat-supply service and unit heating index, during heat-exchangers of the plate type type selecting, and one
Level net supply channel 3 and one-level net water return pipeline 4 medium are temperature-resistant, two grades of screen plate heat exchanger inlets pipeline 5 intermediaries
Matter temperature t3 is equal to two grades of net water return pipeline 9 medium temperature t1, two grades of screen plate heat exchanger inlets pipelines 5 and two grades of web plates
Formula heat exchanger outlet pipeline 6 medium temperature difference can calculate according to radiator heating system, i.e. 20 DEG C or 25 DEG C of temperature difference, so
Reserved 10% area margin, can calculate the area needed for heat-exchangers of the plate type.
Mixed water pipe 7 medium flow and two grades of screen plate heat exchanger inlets pipeline 5 medium flows typically each by etc. flow
Amount design, i.e. flows through that the flow of mixed water pipe 7 and two grades of screen plate heat exchanger inlets pipelines 5 is equal is the 1/ of system total flow
2.According to changing heat Calculation formula:
Q5=C*m5*(t5-t1)
Q4=C*m4*(t4-t3)
The heat exchange amount that Q4: heat-exchangers of the plate type is confessed, W
The heat exchange amount that Q5: heat user end needs, W
The average specific heat at constant pressure of C: fluid, kj/ (kg k)
M1: two grades of net water return pipeline mass flows, Kg/s
M2: mixed water quality flow, Kg/s
M3, m4: flow through the mass flow of heat-exchangers of the plate type, Kg/s
M5: two grades of net supply channel mass flows, Kg/s
T1: two grades of net water return pipeline medium temperature, DEG C
T2: mixed water lines medium temperature, DEG C
T3: heat-exchangers of the plate type inlet ductwork medium temperature, DEG C
T4: heat-exchangers of the plate type export pipeline medium temperature, DEG C
T5: two grades of net supply channel medium temperature, DEG C
According to law of conservation of energy:
Q5=Q4
C*m5*(t5-t1)= C*m4*(t4-t3)
When the timing of total heat exchange amount Q mono-, calculate, if flowing through the mass flow of heat-exchangers of the plate type 1 by mixed water connected mode
M4 is the 1/2 of two grades of net supply channel mass flows m5, and t1 is equal to t3, in the case of average specific heat at constant pressure C is constant.
=2*t5-t1
According to calculating heat exchange amount, according to 10 DEG C of temperature difference, calculate radiant floor heating system global cycle flow, determine two grades of nets
Water return pipeline 9 and the pipeline diameter of two grades of net supply channels 10, count according to the medium no more than 2.5m/s of the flow velocity in pipeline
Calculating, upwards rounding is standard nominal diameter.
Two grades of described screen plate heat exchanger inlets pipelines 5 and two grades of screen plate heat exchanger outlet pipelines 6, according to meter
Mass flow in the pipeline calculated, calculates according to the medium no more than 2.5m/s of the flow velocity in pipeline, and upwards rounding is mark
Quasi-nominal diameter.
Described manual modulation valve 8 and mixed water pipe 7, according to two grades of screen plate heat exchanger inlets pipelines 5 and two grades of web plates
80% calculating pipeline diameter of formula heat exchanger outlet pipeline 6.
Engineering is illustrated
Certain residential quarter, one-level net is designed for/and return water temperature is 110/70 DEG C, and design area of heat-supply service is 100,000 m2, design
Heating measurement takes 60 W/m2, and calculating design heat exchange amount is 6000kW.Use Radiant Floor Heating System, be designed for/backwater
Temperature is 60/50 DEG C.When heat user end uses the common mode that is directly connected to and mixed water connected mode with secondary network, use
Specialty Selection Software carries out type selection calculation.When meeting two grades of collateral resistances and requiring 50KPa, heat exchanger type selection calculation the results are shown in Table 1.
From data in table, in radiant floor heating system, it is directly connected to selection method according to tradition, needs on the contrary
Heat exchanger area to be strengthened is to reduce the resistance of two grades of sides, and this wastes beyond doubt.Heat user end and two grades of nets use mixed water to connect
Form greatly reduces cost of investment, it is achieved that optimize design.
