Abstract
A three-point temp measuring household calorimeter for heat supply is composed of CPU, clock pulse generator connected to CPU, semiconducor temp sensor with output connected to input of CPU for measuring the temp of incoming and outgoing water of heat radiator, semiconductor temp sensor for room temp, display and power supply. Its advantages are low cost, less electric consumption, long service life and convenient installation and application.
Description
The present invention relates to a kind of three-point temp measuring type household calorimeter for heat supply, belong to the calorimetric determination technical field.
When measuring user side heating heat consumption, traditional calorimeter must be with flowmeter, so that measure heating hot water amount.As the applying date be 1996.5.3, the Chinese utility model patent that authorizing day be 1998.9.30, by name " family with heating calorimetric device " discloses a kind of including in order to heat hot water amount's the heating-amount table of water meter of mensuration.Its shortcoming is that power consumption is big, cost is high, the life-span is short and installs and uses inconvenience.
The purpose of this invention is to provide a kind of economize on electricity, cost is low, the life-span is long and easy to install three-point temp measuring type household calorimeter for heat supply.The present invention is based on a known radiator heat-dissipation area computing formula:

This shows: to obtain its mean value again be t as long as record the temperature of heat radiator water-in and water-out
Pj, measure room temperature t simultaneously again
nThe heat dissipation capacity that can obtain heat radiator is the heating heat consumption that the family is used, the heating heat consumption assay method of Here it is 3 temp.-measuring types of user side, we can design three-point temp measuring type household calorimeter for heat supply thus, and needn't re-use traditional hot water flow meter determination method
The invention is characterized in: it is by central processing unit 1, and the heat radiator water-in and water-out temperature sensor 3,4 of the semiconductor-type that the clock signal generator 2 that links to each other with central processing unit 1, output terminal link to each other with the respective input of central processing unit 1 respectively and semiconductor-type temperature sensor 5, display 6 and power Vcc constitute.
Use proof: it has reached intended purposes
In order in conjunction with the embodiments the present invention to be done detailed describing below, now as follows employed accompanying drawing title of present specification and numbering brief introduction:
Fig. 1, the circuit theory diagrams of three-point temp measuring type household calorimeter for heat supply.
Embodiment:
Ask for an interview Fig. 1, central processing unit 1 adopts the extremely low chip AT89C51 of power consumption; Clock signal generator 2 adopts chip DS1305 (16); Its clock end SCL, sheet choosing end SCE, input end SDIO links to each other with the respective end of central processing unit 1 respectively, be sent to the RESET end of central processing unit 1 after the Sheffer stroke gate 7 of the dividing potential drop output terminal PW UP of its pin 6 and power supply VCC through constituting with chip 74HCOO, the mensuration heat radiator advances, the semiconductor transducer 3 that leaving water temperature is used, 4 and to measure the semiconductor-type sensor 5 that room temperature uses all be to constitute with chip DS1821, their output terminal successively respectively with the T1 of central processing unit 1, T0 links to each other with the RXD end, and its input end advances with heat radiator respectively, rising pipe links to each other with the room temperature measuring end; Display 6 adopts XK-2 type LCD, links to each other with the P00-P07 end of central processing unit 1, can show heat radiator water-in and water-out temperature t at random

nQ is the heat radiator heat dissipation capacity with the heating heat consumption; Its P27 that measures control knob S and central processing unit 1 links to each other.
This calorimeter is under clock signal generator 2 is demarcated, press per minute by central processing unit 1 and measure a relevant temperature value, " performance number " that mark current heat dissipation capacity Q multiply by Measuring Time again, can obtain calorific value, and then the measured calorific value that adds up gets final product, and now is exemplified below:
If: heating radiator is selected " four posts 813 " for use, and 8 every group, go out under homonymy is enterprising, bright dress but top have window to cover, and heating radiator is 150mm apart from the windowsill height
