Energy-saving System Using Fresh Air- constant temperature series
1、Working Principle
The basic working principle of this product is in the following
case: We make use of the temperature sensor to detect the air
temperature outside the equipment room. When the temperature falls
below a set value, the inlet valve of the inlet unit will be opened
and the inside air-condition will be closed. As a result , the cold
air out of the room will be brought into the equipment room through
the air blower. Then the cold air will be exchanged with the hot
air emanating from the equipments inside of the room. At the same
time, exhaust valve of exhaust unit will be opened and the heat air
will be expelled in the room so as to meet the temperature
requirement of the equipment room. It will be handled by the filter
when the cold air is allowed in. So the cleanliness of the
atmosphere will also meet the environmental requirement of the
equipment room. It can shorten the operation time of the
air-condition and improve the energy efficiency of the equipments
with the purpose of meeting all the energy-saving requirements of
the equipment room and saving the energy.

6、Analysis of the saving for electricity
①According to the data from Climate Center of Zhejiang Province, the
average perennial temperature is 17 ℃, 2004 ~ 2006, the average temperatures of the province are 17.9 ℃, 17.7 ℃, 18.3 ℃;the time at which the temperature is lower than 20℃(including the whole day in winter and the time at which the
temperature is lower than 20℃ at night in spring and autumn) will not be less than 50% whole year ;
② According to the environmental conditions of communication
equipment room (Temporary Provisions)”, GF014-95 of Ministry of
Posts, surroundings temperature of B-type room is18 ~ 28 ℃.And it was written by the article 76 of "The Prescript and Constitution to Maintain the Power Supply and Air-condition of China
Telecom (for trial implementation)" that the surrounding
temperature of the second-class is 10 ~ 28 ℃;
③Energy-saving system using fresh air-constant temperature series
starts working when the temperature outside the equipment room is below 20℃.The system will supply cooling capacity to the equipment room not
less than 4040W / h ,within a electricity of 0.22KWh;
④Taking the equipment room equipped with an air-condition of 5P as
an example, the in
