1. Product Description

1.1 Overview

SFF flat solar collector is a device that absorbs solar radiation energy and transfers heat to the working medium. After adding the circulating pipe and the insulated water tank, the water temperature is raised.

1.2 Structure

SFF flat solar collector is composed of a heat absorbing core, a casing, a transparent cover, an insulation material and related components.

SFF-p1.2

1. Frame: Alunimum Alloy,

2. Board Inner Core: Purple Copper

3. Layer: Plating Black Chrome (Absorptance 95%, Emittance 10%)

4. Cover Board: 4mm Toughened Glass

5. Heat Conservation: Rock Cotton (Back), Polythene (Side);

6. Back Board: 0.5mm Galvanized Board

1- Ordinary TXT coating: Absorptance 93%, Emittance 45%~50%;

2- Plating Chrome plating coating: Absorptance 95%~96%, Emittance 10%;

3- TINOX (Germany) coating: Absorptance 96%, Emittance 6%.

1.3 working principle

The sunlight is irradiated onto the surface of the heat absorbing body with coating layer through a transparent cover plate, and most of the solar radiation energy is absorbed by the absorber, converted into heat energy, and transmitted to the working fluid in the runner. Thus, the cold working fluid from the bottom of the collector is heated by the solar energy in the runner, and the temperature is gradually increased, and the heated working fluid is discharged from the upper side of the collector into the storage tank. At the same time, due to the increase in temperature of the heat absorbing body, heat is dissipated to the environment through the transparent cover and the outer case, thereby constituting various heat losses of the flat solar collector.

2. Features and Specifications

2.1 Characteristics

Pressure-type solar collector, working pressure 0.6Mpa, test pressure 0.9Mpa.
With selective absorption coating, high absorption, low reflectivity.
Suitable for medium and low temperature requirements below 50 °C.
Due to the structural characteristics, the insulation performance is poor, the heat dissipation is fast when the temperature is high, and the heat loss is large.
In the winter icy area, it is generally do emptying disposal.
Because the heat collecting components are in direct contact with the air, they are easily corroded.
Perfectly integrated with the building and integrated into one.Suitable for installation on flat roofs, pitched roofs and on the ground.
