Air energy water heater and control method thereof

Abstract

The invention discloses an air energy water heater, which comprises a control device (1), a compressor (2) and an external air blower (3), wherein the control device comprises a main controller (1.1), a temperature detection module (1.2), a clock module (1.3) and a wired controller (1.4) which can set a timing on/off time and system time with at least one timing interval. The clock module (1.3) is in electric connection with the main controller (1.1) which is connected with the wired controller (1.4). The invention also discloses a control method of the air energy water heater, and the core thereof is as follows: as the current system time is in each timing interval, the system controls power on/off of the compressor (2) and the external air blower (3) in accordance with a temperature detection control mode; and as the current system time is out of each timing interval, the main controller keeps the compressor (2) and the external air blower (3) at a power-off state and the system does not heat. The air energy water heater is used conveniently and simultaneously can reach the energy-saving and economic effects.

Description

technical field [0001] The invention relates to an air energy water heater and a control method thereof. Background technique [0002] The water heaters commonly used in the market are electric water heaters, gas water heaters and solar water heaters. Among them, the heating efficiency of electric water heaters is not high, and the heat loss is relatively large; gas water heaters have potential safety hazards; solar water heaters can only achieve heating effects when the sky is sunny, and hot water cannot be used on cloudy or rainy days. The air energy water heater is a device that absorbs heat from the air to produce hot water using the principle of refrigeration. It is efficient, energy-saving, safe and reliable, and can be used all day long, making up for the shortcomings of the above water heaters. [0003] A general air source hot water includes a control device, a compressor and an external fan, and the control device includes a main controller, a temperature detectio...

AI Technical Summary

Problems solved by technology

The control method of this kind of prior art air source water heater has the following defects: because the prior art air source water heater works according to the temperature detection control mode, and the temperature detection control mode is based on the upper limit temperature set by the main controller and If the lower limit temperature is used to control the compressor and the external fan to work, since the hot water in the air source water heater will slowly cool down with time, as long as the power switch of the air source water heater is not turned off, the water heater will continue to cycle heating

Under normal circumstances, users will use hot water in three specific time periods in the morning, noon and evening, so it is troublesome to press the switch at least six times a day to turn it on and off. The water heater is always on, and some users usually forget to turn off the power after use, which will waste electricity and greatly increase the electricity bill, thus increasing the financial burden on the user
