Industrial Solar Solutions
Pakistan is a deficient piece of the land regarding energy. The country’s energy crisis is the result of constant negligence and mismanagement of successive governments. The energy crisis has put a deep effect on the county’s economy. In Pakistan, this crisis is increasing day by day Everyone is thinking of different ways to solve this crisis. Some believe that this can be solved by saving energy and others have the intention to increase the use of alternative sources of energy. Some of them argue about generating electricity using hydroelectric power and coal. Each strategy has its own merits and disadvantages.
The shortest possible way to combat energy shortages is to improve the use of solar energy applications in the industrial and commercial sectors. There are many obstacles to growth, such as upfront costs due to taxes and obligations, correct designs, awareness and quality standards that require government attention to eliminate them. Heating the water from solar radiation is one of the applications of Solar Energy.
Types of Solar Water Heaters
Solar water heaters (SWH) are generally available in two types. One is non-pressurized water heating and the other is solar water heater under pressure. In a non-pressurized solar water heater, the collector (vacuum tubes or flat plate) and the tank are mounted in a luminaire and are in an integrated unit. The tank is mounted on the upper part of the collector. No pump is used in this type of system. This system works on the flow of water by gravity from the tank on the solar water tank (stainless steel tank with 55 mm polyurethane insulation) and from this tank to the vacuum tubes.
By the natural convention process, the Hot water circulates and heats the entire tank. It usually takes four hours to heat the water from 300 to 45 degrees in the high season and 60 degrees in the warm season and 90 degrees in the high season. Then the water temperature varies from the ambient temperature. Usually, 50 litres per person per day are taken during the design of the system for domestic use. For the industrial washing and cleaning application, the total water load in terms of flow is calculated to design the system. The total number of solar panels or series connected in parallel depends on the daily water consumption and the required temperature.
The collectors that are used in the pressurized solar boilers can be flat or vacuum tubes. In pressurized solar boilers, the tubes are made of copper and the tubes close and the upper top has a lamp submerged in a water tank through which the heat is radiated into the water in the tank. Copper tubes are filled with ether that expands rapidly when solar radiation falls on the tubes. Then, in this type of system, the water does not end in the copper tubes and, therefore, there is no possibility of oxidation. In systems under pressure, the tank is separated from the collecting unit and no gravity is required.
Types of Circuits
There are two types of circuits: one is a primary circuit and the other is a secondary circuit. In the primary circuit to move the glycol through the circulation pump by the controller, and in the secondary circuit, the water moves through the pump or without a pump for the endpoints. These systems are used in solar pools, solar preheating for boilers, solar heating of spaces, sustainable applications in industries and buildings. Tanks in systems under pressure can have a cage reel or two coils, depending on the type of applications. In large systems where rapid heat exchange is required repeatedly, heat exchangers are also used.
