Description

Energy-saving air source water heater

Technical Field

The invention relates to an air source water heater, in particular to an energy-saving air source water heater, and belongs to the field of application of air source water heaters.

Background

An air source water heater, also called as an air source heat pump water heater, is characterized in that heat in air is conveyed into water through a refrigerant, the traditional electric water heater and a gas water heater obtain heat energy by consuming gas and electric energy, an air energy water heater achieves the purpose of heating water by absorbing the heat in the air, and the heat energy which is about three times of the electric energy can be absorbed to heat the water under the condition of consuming the same electric energy.

The air source water heater has the characteristics of high efficiency and energy saving, the quantity of produced hot water is 4-6 times that of common electric water heaters, the annual average heat efficiency ratio is 4 times that of electric heating, and the utilization efficiency is high.

The new product overcomes the defects that the solar water heater collects heat by depending on sunlight and is inconvenient to install. Because the air source water heater works by medium heat exchange, an electric heating element is not required to be in direct contact with water, the electric leakage danger of the electric water heater is avoided, the possible explosion and poisoning dangers of the gas water heater are also prevented, and the air pollution caused by the exhaust gas discharged by the gas water heater is more effectively controlled.

The air source water heater does not require sunlight and therefore can be placed at home or outdoors. After the water stored in the solar water heater is used up, hot water is difficult to generate immediately, if the electric heating is carried out, a long time is needed, and the air energy water heater can operate in all weather and under pressure for 24 hours as long as the temperature is above zero centigrade. Thus, even if a tank of water is used up, an air-powered water heater can produce a further tank of hot water in about an hour or less. Meanwhile, the safety hidden troubles of electric leakage, dry burning of the electric water heater, harmful gas generation during the use of the gas water heater and the like can be fundamentally eliminated,

the traditional air source water heater is only provided with one water storage cavity, water in the water storage cavity needs to be heated for more than one hour after being used up, and after the heating temperature reaches the set temperature, if a power supply is not switched on, the water storage cavity can be continuously heated in a heat preservation way, and electric energy is lost; in addition, traditional air source water heater need drill fixedly on the wall body during installation, and not only the installation is loaded down with trivial details, has still destroyed the pleasing to the eye and the integrality of wall body.
