Air heaters have any classification
What classification of air heaters air heaters have any classification currently applied in the field of engineering, the air heater (heat pump water heaters) classification is no uniform classification, divided according to the structure and other characteristics of the heat pump, and can be divided into the following species: divided from the heat pump principle of operation: a vapor compression heat pumps, absorption heat pump, and heat a semiconductor chemical heat pump. From the hot water heating, and features to point: static heating, heating cycle, direct thermal heating (i.e. thermal open i.e., maximum efficiency). From the heat source by source: heat pump, heat source soil, waste water source heat pump, air source heat pumps, solar heat. From the heat storage to the embodiment wherein point: hot water thermal storage type, a phase change thermal storage. From the place of use of the heat pump points: Small and medium-sized business units and home machines into two categories. From the heat pump structure: split and monolithic. Different purposes from the use of sub-: domestic hot water heat pumps, heating pump, water pump, heat pump and pool breeding dedicated heat pumps. There are many methods of classification. For example, the heat pump system according to the number of units, but the system can be divided into two systems and a heat pump (heat pump system and some have four); sub-parts from the wind, the wind can be divided into a top, side wind and the wind swash type; the like from the level, type of refrigerant, the compressor structure water temperature, whole or split, aspects of fixed or variable frequency, may be many appropriate classification. The most common engineering classification is in accordance with the heat source to the division: water source heat pump, earth source heat pumps, waste water source heat pumps, air source heat pump and solar heat. Broadly speaking, the water source heat pump, earth source heat pump and waste water source heat pump is the water source heat pump, differ only source of water. For example, the soil source heat pump via the liquid brine after absorbing heat from the soil to a predetermined strand evaporator in a heat pump system.
