The first decade of the 21st century, the whole world against global warming and energy conservation and environmental protection issues, finally evoke humans since the industrial revolution began to undermine the awakening of the earth, into the home in the solar hot water heater, air heat pump water heaters, LED energy-saving lampssolar power and wind power technology innovation such as full swing, more energy saving energy. Century craft of shoemaking industry, an important issue to look for leaner, more energy efficient, more environmentally friendly technology, naturally become contending. Following "after shoe equipment", the heat pump, how reporters will high temperature heat pump applications footwear oven to provide further understanding.

The thing is to understand the air heat pump principle. Figure 1 illustrates the air heat pump airconditioning while the outdoor emissions of heat like a normal air conditioners, indoor, outdoor air heat pump application is recycling the hot air is used to heat water or heated air, and the air-conditioning or cold water will produce. That air heat pump is a way to convert heating water or heated air through the compressor to absorb heat in the air, and this heating than the average electric wire, infrared lamps or steam heating methods must 50 »¥ savings on electricity consumption. High temperature heat pump by definition is the ability to produce a high temperature above 75 ℃ hot water equipment, do not think the general heat pump can be heated to a temperature above 60 ℃, heat pump water heaters on the market in general can only be heated to 55 ° C, widely used in showers and livelihood to use. I serve heart into mechanical hot water temperature can be heated to 85 ℃, even the exhaust temperature was raised to 120 ° C, 120 ° C exhaust gas temperature can heat exchange with the hot air up to 90 ℃ shoe process applications various oven.
