ENERGY SAVING UNITS

ENERGY-SAVING UNIT FOR AIR CONDITION Energy-saving principle: 1. It is known from the running curve of compressor that while compressor approaches lower limit temperature during running, the temperature of the compressor will rise, current grows and the consumed power increases, but the cooling temperature doesn't descend or descend little, by now the output signal of power saver control and stop it and this part of power source is saved. At the same time, fully cool the systems of compressor. 2. The cooling temperature for power saver is 20 ? . After compressor stops running, residual cold air remains in the system. By now the indoor fan keeps working all the time, so the air blown out is cold. When the residual cold air in the system us used up, the output signal of power saver starts the control compressor to work. Such circles achieve the energy-saving purpose up to 30%, after 4h it will be 30%-48%. 3. To avoid frequent start for compressor: Starting and stopping to compressor is controlled by temperature control and frequency conservation of power saver. It stops when indoor temperature is higher than target temperature. It starts when indoor temperature is lower than target temperature. Actual observation is one back and forth several minutes' frequency observation, which belongs to frequent start and produces high impulse current and also consumes electric energy. But the work period of power saver is one back and forth several minutes, which prevent high current against frequent impulse to compressor and extend the age of compressor. Working principle and applicable range: The product adopts the advanced frequency conversion parameter control technology of Honda company in Japan, regulate through the corresponding frequency conversion with the specific requirements of range of temperature to human body, control the range percent of room temperature to an applicable one, set up the optimal regulating rule for power expenditure control range for compressor to make the system be in the optimal working status with least power expenditure. You can choose proper mode of operation by yourself according to your personal specific requirements to living room temperature, change passive consumption to subjective control, which not only can reach the optimal energy-saving effect, but also can obtain comfortable room temperature. Type 01 energy-saving unit for air condition is applicable to hotels/households with areas of 15 m 2 . Type 02 energy-saving unit for air condition is applicable to guest hall/marketplace/office/public places etc with areas of 15-60 m 2 . Type 03 energy-saving unit for air condition is applicable to the condition that special air condition shutting down after starting. Because there are too many people, big fluctuation of thermal load and bad airproof performance in the above mentioned sites, which make the air condition run without stop and cause a great deal of power consumption. This type of saver will make the air condition run in the optimal working status through the control of microcomputer intelligent power saver under the precondition of not affecting temperature and comfortable sensation, simultaneously avoid the man-made improper operation which may cause the lose of electric energy. The power saving rate will up to 30%-48%, which can largely reduce your operational cost. Type 04 is suitable to more than 100 types of air conditions with brand. But the compressor of several special types of air condition keeps working after the air condition start, however the air condition blows out cold air, but no cold blast. Under this condition, only this type of energy-saving unit is applied.
