Description

A heat pump solar water heater

technical field

The utility model belongs to the technical field of solar energy utilization and relates to a solar water heater, in particular to a heat pump solar water heater.

Background technique

A solar water heater is a heating device that converts solar energy into internal energy of water, and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. On the one hand, it reduces the coal, natural gas or electric energy used in the water heating process. On the other hand, the solar water heater has a relatively long life, and the one-time investment will benefit for a long time. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure, and vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. The vacuum heat collector uses the principle that hot water floats up and cold water sinks, so that the water can generate microcirculation to achieve the required hot water.

Because solar water heaters rely solely on sunlight to work, they have relatively high environmental requirements and must have sufficient light, otherwise solar water heaters cannot work effectively. In recent years, due to the deterioration of environmental pollution, the number of haze days in the northern weather has continued to increase, which also means that there is no sufficient sunlight for a long time. In this environment, the function of solar water heaters is obviously insufficient.

In response to the above-mentioned status quo, solar water heaters and air energy water heaters with electric energy auxiliary heating functions have begun to appear in the market, but these types of solar water heaters still need to consume other forms of energy during the reuse process, making solar water heaters no longer a real " green product".

Utility model content

The utility model provides a heat pump solar water heater to solve the deficiencies of the prior art, which uses solar energy to generate electricity to provide electric energy for an air heater, changes the single heating mode of the traditional solar water heater, and enhances the applicability of the solar water heater.

The technical scheme of the utility model is as follows:

A heat pump solar water heater is composed of a water storage tank, a vacuum heat collecting tube, a photovoltaic panel, a water inlet, a water outlet, an exhaust port, an incubator, an air heater and a storage battery.

The outer wall of the water storage tank is an insulated box. The water inlet, water outlet and exhaust port are installed on the left and right ends of the water storage tank. The vacuum heat collecting tube is connected to the water storage tank. The photovoltaic panel is installed under the vacuum heat collecting tube and fixed with the bracket. The board is connected with the air heater, and the air heater is connected with the water storage tank through a pipeline.

Further, the air energy heater also includes an air energy water inlet and an air energy water outlet. The air energy water inlet is located at the bottom of the water storage tank, and the air energy water outlet is located at the top of the side end surface of the water storage tank. The cold water in the water storage tank enters the air heater through the air energy water inlet, and flows back into the water storage tank from the air energy water outlet after being heated.

Further, the electric energy generated by the photovoltaic panel is stored in the storage battery, and the storage battery provides electric energy for the air energy heater for its normal operation.

Effect and benefit of the present utility model are:

(1) In the heat pump solar water heater, a photovoltaic panel is installed under the vacuum heat collecting tube, and the photovoltaic panel is used to convert solar energy into electrical energy and store it in the battery to improve the utilization rate of solar energy;

(2) The air energy heater uses the electric energy in the battery to heat the water source in the water storage tank, and can also heat the water source when the light is not sufficient, which enhances the environmental adaptability of the solar water heater;

(3) Solar water heaters directly heat water or use air heaters to heat water. The energy is all obtained from solar energy, which is energy-saving and environmentally friendly, green and pollution-free.
