| The energy-saving control
system of central air condition |

[outline]
The central air condition has the extremely widespread application
in the large-scale market, the supermarket, the office building, the
hotels and the factory. Because of the different request to the refrigerating
output due to the great temperature difference between the different
quarters in a year and between morning, noon and evening in a day,
the central air condition has big waste. Along with the development
of science and technology, the main engine of present central air
condition has the function of automatic control, which may adjust
the output power with the change of external temperature, but the
circulatory system still depends on the method of the add-and-subtract
work pump, and then the problem between the large capacity and small
temperature difference has still not been solved. The ZNR intelligent
energy-saving control system for central air condition founds the
variable-frequency energy-saving system according to collect the temperature
parameters of inlet and yielding water, which may steplessly adjust
the flux of circulatory system and the wind rate of wind system with
the temperature change in the entire process to make the running of
whole system in the optimum condition.
[power-saving space]
When design the central air condition or chose the equipment lectotype,
it is deferred to the highest temperature in the history and preserves
the allowance of 15~20%. That is to say, even if in the hottest season,
the air conditioning has the allowance, which is called the design
allowance (except special circumstance).
In addition, in the several months of a
year when the air condition needs to turn on, the difference of temperature
is very large. For example, the allowance in May is larger than in
August, which is shown in Figure 1 (qualitative expression)
