Patent JP-S6152538-A (JP)
Title: Ventilator
Inventor: MIYANARI MASAHARU
IPC: F24F7/08
Filed: 1984-08-23
Abstract: PURPOSE:To make it possible to carry out a heat recovery ventilation by the low output operation of a heat pump due to the natural ventilation at night-time where the ventilation load is small by providing a condenser at a lower conducting port and an evaporator at an upper conducting port respectively, and enabling the changeover of the heat pump to the low output operation. CONSTITUTION:Conducting ports which communicate the indoor side and the outdoor side with each other are provided at the upper part and the lower part. A condenser 4 is provided in the lower conducting port 12, and an evaporator 2 in the upper conducting port 18. Further, on at least one of these conducting ports is provided a blower 7. The condenser 4 and the evaporator 2 are connected to each other by means of a coolant pipeline of a heat pump including a compressor 1 and an expansion valve 3. When the blower comes to a stop, a natural convention occurs due to the relation between the room temperature and the external air temperature to enable the heat recovery ventilation in such a natural ventilation. Therefore, a bypass valve 5 is opened to reduce the turn-down quantity of the coolant. When the ventilator is used in a case where the ventilation load is small such s during sleeping, the blower is stopped and the heat pump is changed over to the low output operation, whereby the ventilation of high efficiency can be carried out.

Title: Resonant converter and its output voltage control method
Inventor: TAGUCHI TAKAYUKI
IPC: H02M3/28
Filed: 1990-07-04
Abstract: PURPOSE:To keep output voltage at a second output voltage set value practically without lowering the power efficiency even at light load or no-load by equipping, on input side, a capacitor voltage control circuit, which lowers the voltage of a capacitor for resonance depending upon the magnitude of the signal from an error amplifying circuit. CONSTITUTION:When it becomes light load or no load and the voltage between DC output terminals To and To' exceeds the second output voltage set value V2 higher than the first output voltage set value V1, an error amplifying circuit 8 gives the signal S2 equivalent to the voltage difference between them to a capacitor voltage control circuit 10 through an isolation circuit 9. At this time, a transistor 11 is controlled by the voltage of a resistor 7 proportionate to the magnitude of the error signal S2 from the error amplifying circuit 8 and proportionate to the current. On the other hand, a capacitor 13 is connected to a capacitor 3 for resonance through a diode 14, and also since the voltage by resonance is set to be higher than the input voltage between input terminals Ti and Ti', the capacitor 13 is charged to the voltage approximately as high as the voltage of the capacitor 3 for resonance.
