Problems solved by technology

There is a problem with this method. When the evaporation heat is converted into condensation heat release, the original condensation heat release is also converted into evaporation heat absorption. During the defrosting process of the air energy water heater, the heat energy in the water tank will be absorbed by the refrigeration system, and the water temperature will drop.
When the defrosting is over, the four-way switching valve restores the original refrigerant flow direction, and the hot and cold refrigerants in the heat exchanger pipeline are neutralized, and part of the heat will be lost.
The heat loss in the whole defrosting process is very large, which is not conducive to energy saving

Embodiment 1

[0019] Embodiment 1: as figure 1 As shown, the air energy water heater of the present invention includes a housing 1, a main controller 2 located in the housing 1, a compressor 3, a fan 4, a preheating device 5, a water temperature sensor 6, an ambient temperature sensor 7 and a disk A tube temperature sensor 8, and a display operator 9 communicated with the main controller 2 is provided on the outer wall of the housing 1. The main controller 2, as the core component of the air energy water heater, communicates with the The compressor 3, the fan 4, the preheating device 5, the water temperature sensor 6, the ambient temperature sensor 7 and the coil temperature sensor 8 are electrically connected. 9. Turn on the air energy water heater, and display various working information, such as water temperature, time and so on. Among them, the water temperature sensor 6 , the ambient temperature sensor 7 and the coil temperature sensor 8 all use R25°C=5kΩ, B=3470 type sensors, which h...

Embodiment 2

[0026]Embodiment 2: This embodiment differs from Embodiment 1 only in that: the standard water temperature Tw1 for preventing frost formation is set at 25° C., the standard ambient temperature Ta1 is set at 6.5° C.; the standard ambient temperature Ta2 for defrosting is set at 6.5° C. °C, the coil temperature Tp1 is set to 3.8 °C during standard frosting.

[0027] The standard water temperature Tw1, the standard ambient temperature Ta1, Ta2 and the standard coil temperature Tp1 during frosting are all relatively higher than that of Example 1, and the effects are basically the same.

Embodiment 3

[0028] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the standard water temperature Tw1 for preventing frost formation is set at 18° C., the standard ambient temperature Ta1 is set at 5.5° C.; the standard ambient temperature Ta2 for defrosting is set at 5.5° C. °C, the coil temperature Tp1 is set to 3.2 °C during standard frosting.

[0029] The temperature of the standard water temperature Tw1, the standard ambient temperature Ta1, Ta2 and the standard coil temperature Tp1 during frosting is relatively lower than that of Example 1, and the effects are basically the same.

Description

technical field [0001] The invention relates to an air-energy water heater, in particular to an air-energy water heater, a method for preventing frosting, and a method for defrosting. Background technique [0002] The air energy water heater uses the heating principle of the air conditioner to absorb the heat in the air to generate heat through the evaporation of the medium. It has the advantages of energy saving, environmental protection and safety of the solar water heater, and solves the problem of the solar water heater relying on sunlight for heating and inconvenient installation. Since the air-energy water heater heats through the exchange of heat between the medium and the air, there is no need for electric heating elements to contact water, there is no danger of electric water heater leakage, and the hidden danger of poisoning and explosion of gas water heaters is also eliminated, and there is no air pollution caused by exhaust gas from fuel water heaters. . Because...
