Problems solved by technology

[0003] At present, solar energy and air energy hot water devices on the market are generally affected by the weather. The excess hot water in summer causes the equipment to be idle, and the hot water in winter is not enough.

Solar energy and air energy hybrid water heaters are generally equipped with only one water tank, and tap water is used as the collector medium. When not in use, the water heated to a sufficient temperature in the collector will be replenished into the water tank, and then the tap water will be supplied to the collector. In general, when the water in the water tank is full, the water in the water tank and the water heated in the collector will circulate to ensure a constant water temperature. Once water is used, the water level in the water tank will drop, and then The water in the collector is replenished to the water tank. Once the water in the collector is used up, the tap water will be replenished in the water tank, which will cause the hot water with sufficient temperature in the water tank to mix with the tap water, so that the water temperature in the water tank will drop, thereby starting the air energy unit. Due to the slow heating effect of the air energy heating device, the rising speed of the water temperature is not obvious, so that the user uses less hot water. At the same time, the premature use of air energy increases the power consumption, and the circulation between the collector and the water tank It is done by the circulation pump, the circulation pipeline is too long to cause heat loss, excessive use of electric energy, and the long-term operation of the circulation pump requires high maintenance costs
