1, Project Overview

This of Weifang residential heating in the building area of ​​115 square meters. 2, the electric compensation parameters

Complementarity of solar heating heating system is running, cold, rain, snow, cloudy meteorological impact of solar

heat at night is insufficient to take electric compensation. The following is a group of Shandong Weifang 115 square

meters of residential operating parameters: design ideas

The design system for the love of sun solar heating and bath system. Used a total of 16 square meters of outdoor

solar. To meet the daily hot water and heating needs.

4, the love the sunnier computer intelligent control and electronic complement of six leading international technology

We all know that love more than the sun solar heating in the domestic sales of the first and only indoor temperature

in winter can reach 18 to 25 degrees, the solar total energy consumption 70% to 90% of the solar heating business, why

on the market today modeled on the love of multi-sun solar heating manufacturers to add solar electric boilers or

electric heating, the maximum heating temperature can only reach 12, 13 ° C, the highest solar energy can only reach

20% ~ 30% utilization?

The main reason is: my company to integrate the most advanced solar energy, home appliances, electronic six technical

perfection in a solar heating control and electrical complement system: inverter technology; speed heat and thermal

technologies; automatic mixing with water technology ; parameters of energy conservation and a key energy-saving

technologies; room temperature, water temperature dual optimization control technology; water temperature, water flow,

fuzzy control technology.

First, the United States and Japan from air conditioning inverter technology:

The air conditioning industry s most popular inverter technology, the company inverter technology used in solar

heating control system, the advantage of the control system according to room temperature, the temperature difference

between water temperature and set temperature, intelligent fuzzy adjust the heating power, in the same effect, saving

1/3 or more than ordinary heating. For example, when need electricity to make up the variable frequency heating, as

the temperature approaches the setpoint, the heating power from 100% to 0% intelligent switching, the higher the

temperature the lower input power, until the room temperature reaches the set temperature.

Second, from the Europe-speed heat and thermal technologies:

Eight years ago, Europe began to rise-speed thermal water heaters, its advantages is the rapid increase in water

temperature, with the number of burn Heat the whole bucket of 60 liters or 80 liters of water, unlike traditional

storage water heaters before use to be, do not heat the hot water wasted. I will speed heat and thermal technology

used in solar heating control system, the advantage to make up heat much faster rate once it reaches a set temperature

heating needs, you automatically enter a state of the heat retaining, as fountains of heat retaining can make the room

temperature, water temperature in the case of extremely low power consumption is maintained at a quasi-constant

temperature to meet heating demand for heat.

, Automatic mixing water technology:

Solar heating control system, advanced automatic tracking water temperature automatic mixing with water, the water

temperature of solar heating and electricity make up the water temperature is always maintained relatively constant

temperature. Temperature flow pressure measurement and control pump operation. Automatic mixing with water to extend

the utilization of solar energy time, reduce the frequency and duration of electric heating, to avoid the solar water

heating, hot water and electricity make up invalid waste, greatly enhance the effective utilization of solar heat

source and heating source.

Fourth, the parameters of energy-saving and a key energy-saving technologies:

(1) the four parameters of energy-saving: The system panel temperature of the solar collectors, solar collector

temperature difference, heating water supply temperature, indoor temperature and other control programs in order to

set parameters. Scientific and reasonable parameter settings can improve the utilization of solar energy to reduce

electricity consumption. A brief description is as follows:

(1) solar collector temperature is set according to the method of heating to set the start temperature of the solar

heating. Started using geothermal coil radiant heating, set up solar circulating pump temperature 35 ~ 40 ℃ is

appropriate for wall radiators or fan coil heating, to set up solar circulating pump start temperature of 45 ~ 50 ℃

is appropriate.

② solar collector temperature difference is set according to the solar collector area to set up operational control

of the temperature difference between solar collector system. Larger solar collectors, solar heating time is longer,

the temperature difference can be set between 5 ~ 9 ℃; solar collector area of ​​less solar heating time is shorter and

has a stage run, the temperature difference can be set in 2 ~ 4 ℃.

(3) heating water supply temperature to set the size setting is set according to the heating thermal load. Heating

heat load should be set higher water temperature, the heating heat load should be set to a smaller water supply

temperature is lower. The water temperature is set high energy consumption will increase the water temperature is set

low the energy saving effect. Each increase or decrease the 1 ℃ energy consumption will increase or decrease by about

17%. Heating water temperature and solar collectors at the same temperature or low 1-2 ℃ appropriate.

Requirements set the ④ room temperature according to the heating room temperature. If not using the room temperature

control mode or not set.

(2) a key energy-saving technologies: In the winter 70% to 90% of the time using energy-efficient power of 2/3 or less

of the total system power for heating, greatly reduces the electrical energy consumption in the running.

Five at room temperature, water temperature, the dual optimization control technology:

This system at room temperature and water temperature are set preferred room temperature operation, due to room

temperature can be selected between 8 ~ 28 ℃ or even higher, herbs processing (such as a user need to room

temperature 37 degrees, the annual temperature). Office evenings or school holidays, villas usually do not live can be

based on the actual room temperature is set at 8 to 15 degrees, while maintaining the indoor warm ice-free, but also

save operating costs.

Selective water temperature can also be used as low temperature, frost and energy-saving protection settings to apply.

6, water temperature, water flow fuzzy control technology:

The first heat source of this system is the solar collectors provide solar heat source; second heat source is provided

by the electric auxiliary heat source.

The operating principle is as follows: under the management control system, as long as the solar collector temperature

to meet the temperature requirements set, the system will work with the first heat source, the second heat source does

not work; only the temperature of the solar collector can not meet the set when needed the second heat source in

operation. Second heat source in the role of automation systems, when the indoor temperature is below the set

temperature 1 ° C, the electric compensation 1 ℃ temperature difference input variable frequency 1/16 power put into

operation, if the water temperature can not be reached very quickly on the request or at room temperature continued to

decline to re-enter 1/16 power, and so gradually put into power, until room temperature or water temperature reaches

the set temperature.

Water temperature flow of the design through the topological principle of fuzzy control technology, to achieve the

organic combination of the temperature probe and flow valves, circulating pumps in the system, the entire heating

season, if you do not control buttons, and can make the entire solar heating system and hot water system in accordance

with the initial setup to run automatically, unattended, and significant savings in labor costs.
