Abstract: This disclosure generally relates to an automatic bicycle, particularly to a hydraulic automatic transmission bicycle which can automatically and adaptively change gear ratios. More particularly, this disclosure relates to those hydraulic automatic transmission bicycles which use fluid pressure to change such gear ratios, and which include various hydraulic automatic transmissions which may be provided in various configurations and may operate in various methods and sequences to provide automatic and infinitely variable gear ratios.

Abstract: A heat pump configured by connecting a circuit including a variable capacity compressor, a condenser, an expansion valve, and an evaporator through a closed refrigerant line, includes a condenser fan, an evaporator fan, a refrigerant amount adjusting means for charging or recovering a refrigerant in or from the circuit, and a controller. Roles of the controller include setting a target pressure inside an outdoor heat exchanger y referring to an outside temperature and a load, setting a target pressure inside an indoor heat exchanger by referring to an inside temperature and a set temperature, setting a target sub-cooling degree and a target super-heating degree, and controlling both of the fans to either adjust temperature or adjust pressure.
