DESCRIPTION

What is a split pressure solar water heater?

In the case of a split pressure system, hot water storage tank and collectors are installed separately from each other. Split pressure system is equipped with a recirculating pump which circulates the water through the roof-mounted collector and back into the hot water tank.

Split solar energy is the solar energy that separates the water tank and the heat collector. The heat collector and the water tank are connected by pipelines. The energy of the electromagnetic radiation of the sun is forced to circulate through the water pump to gradually collect the heat of the heat collector into the water tank, thereby heating the water. , To meet the market demand for domestic hot water. Household split solar energy is generally divided into wall-mounted solar energy and rooftop solar energy. Split solar energy is basically pressure-bearing, and most of them use flat-plate collectors.

Split pressure solar water heater uses principle of water pressure. By absorbing heat and change pressure balance of water tank and solar collector,cold water and hot water circulate as per pressure difference, water temperature is adjusted to realize heating.

Work theory

Working principle

The split pressurized solar water heater composes of solar collector, storage tank, controller, working station and installation parts.

1) When the discrepant temperature of the solar collector and water tank reaches the set value, the controller shall start the circulation pump automatically.

2) The circulation pump makes heat-conducting liquid circulate automatically.

3) The heat-conducting liquid transfers heat to water by heat exchanger in the water tank.

4) In case the temperature of the water tank does not reach Tmax, then start the auxiliary heating device.

If discrepant temperature of the collector and the water tank does not reach the set value, the circulation pump shall be shut automatically.

1. Heat absorption: The split solar water heater absorbs heat through the glass cover, and the absorbed heat will be concentrated in the pipe wall and transferred to the water in the hot water pipe through the pipe wall. The temperature of the heat absorption tube is greatly increased, and the water will be heated regardless of the temperature. The heated water will drop greatly through the water storage tank, and it will still be replenished with the low-temperature water. In this way, the water in the tank will slowly reach the same temperature.

2. Heat collection box: Split type solar water heater has water inlet and outlet. It has a heat collection box. The water in this heat collection box flows in through the heating pipe when there is no sunlight. Split-type solar water heaters will use circulation pipes for heating. The circulation pipeline will store the heat absorbed by the solar energy, and circulate the operation when there is no sun to heat the water.

3. Pressure bearing device: The split solar water heater has a pressure bearing device, which mainly uses the principle of water pressure. By absorbing heat, the fluid in the water tank and the heat collecting tank is transformed to form a circulation of cold water and hot water, thereby heating. This device is to adjust the cold water and hot water to control the temperature of the water.

1. Absorción de calor: El calentador de agua solar dividido absorbe calor a través de la cubierta de vidrio y el calor absorbido se concentrará en la pared de la tubería y se transferirá al agua en la tubería de agua caliente a través de la pared de la tubería. La temperatura del tubo de absorción de calor aumenta considerablemente y el agua se calentará independientemente de la temperatura. El agua calentada caerá en gran medida a través del tanque de almacenamiento de agua y aún se repondrá con el agua a baja temperatura. De esta manera, el agua del tanque alcanzará lentamente la misma temperatura.

2. Caja de recolección de calor: El calentador de agua solar tipo split tiene entrada y salida de agua. Tiene una caja colectora de calor. El agua en esta caja de recolección de calor fluye a través de la tubería de calefacción cuando no hay luz solar. Los calentadores de agua solares de tipo dividido utilizarán tuberías de circulación para la calefacción. La tubería de circulación almacenará el calor absorbido por la energía solar, y hará circular la operación cuando no haya sol para calentar el agua.

3. Dispositivo de soporte de presión: El calentador de agua solar dividido tiene un dispositivo de soporte de presión, que utiliza principalmente el principio de presión de agua. Al absorber calor, el fluido en el tanque de agua y el tanque colector de calor se transforma para formar una circulación de agua fría y agua caliente, calentando así. Este dispositivo sirve para ajustar el agua fría y el agua caliente para controlar la temperatura del agua.

Disadvantages of split solar water heater

In winter or rainy days, because the water temperature in the water tank is too high, the water temperature will drop quickly, and electricity must be used for auxiliary heating. The thermal fluid must be replaced regularly. Generally, the thermal fluid must be replaced once every five years, otherwise it will negatively affect the heat transfer efficiency.

With the development of the times and the advancement of science and technology, the company is committed to the application of new concepts, new thinking and new technology with the purpose of "pursuing excellence", fully implementing new breakthroughs in European Standard Split Pressure Solar Water Heater products, and striving to provide users with New equipment with high grade, high performance and commercial efficiency to promote the rapid development of the national economy. We sincerely hope to establish some satisfactory relationships with you in the near future. Our company follows the development policy of 'talent, management, technology and service', and the enterprise goes up to a new level every year.
