Abstract
The invention discloses an electrothermal heating thermal frequency converter. The frequency converter comprises a power module unit, a frequency adjustment unit, a microcomputer module unit, a temperature control unit and a temperature sensor unit, and is characterized in that the microcomputer module unit is respectively connected with the power module unit, the frequency adjustment unit, the temperature control unit and the temperature sensor unit; the frequency adjustment unit is connected with temperature control unit to output variable frequency alternating currents. The operating temperature of heating equipment is collected, then alternating current frequency used for changing of a heater is calculated, energy consumption of the heater is reduced, meanwhile the surface temperature of the heater is controlled within the range of 90 DEG C+/-5 DEG C.
Description
Technical field
The present invention relates to electroheat technology field, is the hot frequency converter of electrothermal heating specifically.
background technology
At present, the various electrothermal heating equipment of China mostly adopts the form (national standard 90 ℃ ± 5) of heater temperature from limit, thermistor control appliance surface temperature or temperature switch control appliance surface temperature, the energy conservation standard of its equipment own is low, energy consumption is larger, only have by indoor temperature expander and realize energy-conservation (6-8h works every day), generally, it is the heating equipment every day (24h) of 1kw, work 6-8 hour, that is: 1kw × (6-8h)=6-8(kw.h), for example: usable floor area 20m
2room, in the cold north, winter heating needs 120w/m
2heat energy,
That is: 20m
2× 120w/m
2=2400w
2400w/1000×(6-8h)=14.4-19.2（kw.h）
In the electricity price situation of 1(kw.h)=0.5362 yuan/kw.h: every day, (24h) needed 7.7-10.3 unit
150 days (northern heating phase), usable floor area 20m
2room needs 1155-1545 unit, square metre expense 57.75-77.25 unit/m
2, existing northern heating expense is 29.55 yuan/m
2, find out thus and adopt the expense of electrothermal heating considerably beyond the expense of ordinary hot water warm.
Our country widelys popularize clean heating technology now, can be crucial be exactly that operating cost problem has restricted the paces that advance, this contradiction is particularly outstanding.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, and a kind of simple in structure, hot frequency converter of the obvious electrothermal heating of energy-saving effect is provided.
The hot frequency converter of electrothermal heating of the present invention, it comprises power module unit, frequency adjustment unit, micro computer modular unit, temperature control unit and temperature sensor unit, it is characterized in that: described micro computer modular unit respectively with power module unit, frequency adjustment unit, temperature control unit, temperature sensor unit connect; Described frequency adjustment unit is connected with temperature control unit, the alternating current of output frequency conversion.
The hot frequency converter of aforesaid electrothermal heating, is characterized in that: described frequency converter is arranged on the frame place of heat collector.
Wherein said electric heating device hot frequency converter one end and 220V power supply join, power module unit provides working power to micro computer modular unit, frequency regulation block unit, temperature control modules unit, temperature sensor unit by gather transfer of data to micro computer modular unit, micro computer modular unit is by calculating, instruction is issued to frequency regulation block unit and temperature control modules unit, frequency regulation block unit changes the frequency of heat collector alternating current, and temperature control form unit piece guarantees that heat collector surface temperature is 90 ℃ ± 5.
Technique is the operating temperature by gathering heating equipment, then changes the ac frequency of heat collector by calculating, reduces the power consumption of heat collector, reaches simultaneously and controls heat collector surface temperature in 90 ℃ ± 5 objects, and its device energy conservation is reached more than 45%.
That is: 1kw power consumption=0.55(kw.h)
Usable floor area 20m equally
2room, in the cold north, winter heating needs 120w/m
2heat energy,
That is: 20m
2× 120w/m
2=2400w
Electricity consumption of equipment amount=2400w/1000 × 1h × 0.55=1.32(kw.h)
Install additional after indoor temperature controller=1.32(kw.h) × (6-8h)=7.92-10.56(kw.h)
In the electricity price situation of 1(kw.h)=0.5362 yuan/kw.h: every day, (24h) needed 4.25-5.62 unit.150 days (northern heating phase), usable floor area 20m
2room needs 637.5-843 unit, square metre expense 31.88-42.15 unit/m
2, existing northern heating expense is 29.55 yuan/m
2, find out thus and adopt the electrothermal heating expense of hot converter technique only to surpass ordinary hot water warm expense 2.33-12.6 unit/m
2.The heat collector time of working at night accounts for 70%, if can use time-of-use tariffs, its operating cost is definitely lower than traditional hot water heating expense.
