Air energy water heater

Abstract

The invention discloses an air energy water heater which comprises an inner container and a heat exchange coil. The heat exchange coil is located in the inner container, two ends of the heat exchange coil penetrate through the inner container, and the heat exchange coil is of a double-layer coil structure. The double-layer coil is built in the inner container to perform heat exchange, the length of a heat exchange tube in the inner container is increased through the double-layer coil, a heat medium can perform full heat exchange in the inner container, and meanwhile the whole air energy water heater is invariant in size, simple in structure, high in heat transfer efficiency, low in energy consumption and manufacture cost. Compared with a traditional air energy water heater box in which clean keeping, sterilization and descaling cannot be achieved, a detachable inner coil heat exchanger is assembled in a heat storage water tank of the enamel inner container of the air energy water heater, can be used for daily dismounting and cleaning, descaling, sterilization and disinfection and maintenance and enables each hair follicle respiratory system on the body of each consumer using the air energy water heater to enjoy clean and sanitary heat accumulation warm water.

Description

technical field [0001] The invention relates to a water heater, in particular to an air energy water heater. Background technique [0002] In the prior art, the heat exchange tube and the inner tank of the air energy water heater usually adopt an external heat exchange, that is, the heat exchange tube surrounds the inner tank to heat the water in the inner tank. This heating method is not sufficient for heat exchange. , the loss of heat is very large and the energy consumption is high. There is also a built-in heat exchanger, that is, the heat exchange tube coil is used to exchange heat inside the inner tank. Due to the limitation of the inner space of the inner tank, the length of the heat exchange tube is relatively short in this way, and it is also unable to perform sufficient heat exchange. , Therefore, a heat exchange device adopting multi-stage heat exchange appears, and this method has the defects that the heat exchange device occupies a large space, has a complicate...

[0002] In the prior art, the heat exchange tube and the inner tank of the air energy water heater usually adopt an external heat exchange, that is, the heat exchange tube surrounds the inner tank to heat the water in the inner tank. This heating method is not sufficient for heat exchange. , the loss of heat is very large, and the energy consumption is high

There is also a built-in heat exchanger, that is, the heat exchange tube coil is used to exchange heat inside the inner tank. Due to the limitation of the inner space of the inner tank, the length of the heat exchange tube is relatively short in this way, and it is also unable to perform sufficient heat exchange. Therefore, a heat exchange device using multi-stage heat exchange appears, and this method has the defects of large space occupied by the heat exchange device, complex structure and high manufacturing cost
