Light-controlled thermostatic integrator

Abstract

The invention mainly discloses a light-controlled thermostatic integrator. The integrator, an optical sensor, a water level sensor, a temperature sensor, a workpiece display panel, a bidirectional circulating pump, an electric heating bar, and an inner water tank, a plurality of control valves, a plurality of one-way valves, a filter valve, an exhaust port, multiple access pipeline ports, an automatic booster pipeline and the like serving as accessories form the whole running system, wherein the sensors correspond to the integrator. The external rays are detected through the optical sensor, and automatic control and operation of the whole system are finished by the integrator through detection of each sensor according to programming. The integrator has the characteristics of capabilities of allowing a solar water heater to synchronize with light and keeping constant temperature duly by adopting electric heating, strong practicability, high automation degree and the like.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a light-controlled constant temperature integrated controller. Background technique [0002] As a clean and pollution-free green environmental protection device, solar water heaters are becoming more and more popular. At present, most of the popular solar water heaters on the market are desktop or pressure-bearing wall-mounted. The main form of the desktop is that the water tank is connected with the vacuum tube; the pressure-bearing wall-mounted structure is that although the water tank and the collector are separated, the vacuum tube of the collector and the water tank are connected together through a closed metal tube. The working principle of the desktop is: the vacuum glass is irradiated by sunlight, which makes the water in the tube heated and buoyant, and exchanges heat with the water in the heat preservation water tank to achieve the temperature rise of all the water. There are f...

AI Technical Summary

Problems solved by technology

[0003] First, the heat exchange of water in the vacuum glass tube is a natural exchange in a single body tube. When the temperature is not high, the speed of this heat exchange transfer is very slow, and the heat exchange efficiency is very low.

[0004] Second, because there is no integrated controller installed, it cannot perform automatic operation, nor can it run synchronously with the actual light, and its thermal efficiency is low

[0005] Three, since the water tank is connected with the vacuum tube, and the water tank is above the vacuum tube, the water in the vacuum tube can never flow back to the water tank for use

Moreover, the water in the vacuum tube is never replaced, so its scale is serious, and its water quality continues to deteriorate over time.

[0006] Fourth, the solar water heater is placed outdoors, and the heat dissipation of the water tank is large. Under low temperature and low light in winter (such as at night), the solar water heater and the indoor water inlet and outlet pipes are easy to freeze and crack

[0007] Fifth, the water heater cannot control the water level of the water tank during the electric heating process, so the electric energy consumption in the electric heating process is large, the waste is also amazing, and the heating rate is very slow

[0009] First, the thermal efficiency of natural circulation is low

[0010] Second, the temperature sensor equipped with a temperature difference controller is easily damaged under high temperature and air drying conditions, and the sensor is easy to affect the control operation due to the decrease in sensitivity of the dirt.

[0011] Third, it requires secondary heat exchange, so its thermal efficiency is not high

[0012] Fourth, because the water tank is always fully loaded under pressure, the water level in the water tank cannot be controlled during the electric heating process, and only the whole bucket of water can be heated, so the consumption of electric energy is huge and the waste is amazing, and the heating speed is also very fast slow

[0013] Fifth, due to the need for high-pressure and pressure-bearing operation in the circulating metal pipeline, and the high-pressure and pressure-bearing operation in the water tank, the safety is low, and once there is a fault, the maintenance is difficult, highly professional, and the cost is also very high
