Abstract
A hot-air supplying method that includes: generating, by means of a heat pump, hot air that is at a temperature lower than a desired target hot-air temperature; subsequently heating, by a heater, the hot air having been generated by the heat pump, while controlling the heater the temperature adjuster so as to adjust the temperature of hot air thus heated to the target hot-air temperature. This makes it possible to supply, with reduced energy loss and at low costs, hot air for processing a work, the hot air being necessary in a factory where processing and assembly or the like are carried out. Further, temperature control accuracy is enhanced.
Claims14
A hot-air supplying device for a processing device that processes a work, the hot-air supplying device comprising:
- a heat pump configured to generate hot air at a temperature lower than a target hot-air temperature necessary for the process, the heat pump being connected to both a suction path to suck air into the heat pump and a preheated hot air supply path;
- a heater configured to heat the hot air generated by the heat pump and supplied by the preheated hot air supply path;
- a temperature adjuster configured to control the heater so that the temperature of the hot air, generated by the heat pump, is further heated to adjust the generated hot air to the target hot-air temperature;
- and
- a bypass that directly connects the suction path and the preheated hot air supply path such that air from the suction path is directly introducible into the preheated hot air supply path.
A hot-air supplying method for supplying hot air to a processing device that process a work, the hot-air supplying method comprising:
- generating, with a heat pump, hot air at a temperature lower than a target hot-air temperature necessary for processing;
- connecting the heat pump to a suction path to suck in air and a preheated hot air supply path;
- subsequently heating the hot air generated by the heat pump and supplied by the preheated hot air supply path, while controlling a heater, which heats the generated hot air, with a temperature adjuster so that the temperature of the generated hot air is adjusted to the target hot-air temperature;
- and
- connecting the suction path and the preheated hot air supply path via a bypass so that air from the suction path is directly introducible into the preheated hot air supply path.
