Description
Product Introduction:
With the upgrading of the solar thermal industry and strong national support for the development of solar‑thermal application products, R&D and quality requirements are continually rising. It is no longer sufficient to merely impose stringent quality controls on the thermal and optical performance of solar water heaters and collectors; rigorous quality assurance and testing must also address their outdoor durability and freeze‑resistance. In response to relevant testing standards, a dedicated freezer‑box test system has been developed. This system is primarily used to simulate the harsh natural conditions encountered in outdoor applications, enabling assessment of whether solar water heaters or collectors exhibit leaks or damage.
Results such as damage, deformation, distortion, cracking, and water leakage. While measuring the thermal performance and energy efficiency ratio of solar water heaters or collectors, the system can simultaneously conduct durability and physical‑property tests on two to three units, thereby overcoming the limitation that thermal‑performance and efficiency measurements cannot be performed concurrently, significantly improving work efficiency and saving time. This system is suitable for a wide range of solar water heater manufacturers, quality‑inspection institutes, testing centers, research institutions, and major universities.
For industry‑specific and other types of testing.
Product Features:
1. It features an exceptionally wide temperature control range, accommodating a variety of user requirements, and offers rapid heating and cooling rates, ensuring high testing efficiency.
2. It employs a unique balanced temperature‑control method, enabling adjustment to an ideal ambient temperature. Featuring stable, equilibrium‑based cooling, it delivers highly precise and consistently reliable temperature regulation.
3. Equipped with an intelligent controller, thereby significantly improving setting accuracy;
4. Automatic selection of the refrigeration circuit: The control system automatically selects the appropriate refrigeration circuit based on the set temperature, enabling direct startup of the chiller for cooling under high-temperature conditions. The refrigeration unit employs a air-cooled Bitzer compressor package.
5. The door is equipped with a lighted observation window, allowing convenient monitoring of the test sample’s condition.
6. One set of manually operated, double-sided color steel sliding door, with a doorway dimension of 1800×1700;
7. Observation Window: An observation window measuring 200×300 mm (width × height) is installed in the door, equipped with a fully transparent, coated anti-frost device. During low-temperature testing, the outer surface automatically heats evenly, allowing real-time monitoring of changes in the test product inside.
8. The pump features an advanced structural design that completely eliminates impurity‑induced blockages; its motor employs a sealed construction for extended service life; it is equipped with a heat‑dissipating fan, making it suitable for boosting high‑temperature water (up to 100°C); it utilizes a specialized centrifugal impeller that generates very low noise (whereas domestically produced pumps tend to be noisy and less reliable); and its hydraulic components are crafted from special materials and coated to resist corrosion.
9. Dry‑burn prevention and no‑load rotation protection device: 1 circuit/set, high‑temperature type. Used to protect the insulation control cabinet of the mixing pump, it effectively prevents dry burning inside the heater and ensures safe no‑load operation of the mixing pump, among other functions.
10. Equipped with a high-performance microprocessor as the main control CPU, a large-capacity data memory, and a data sampling rate exceeding 0.3 seconds per channel, it features a standardized control design, a large-screen Chinese-character LCD display, and simple operation. It is well-suited for use in harsh industrial environments.
11. The software complies with national standards such as GB/T 19141-2003, GB 6424-2007, and GB 17581-2007, and can run on Windows 2000 or later. It provides real-time display of data from all channels, automatically stores test results (with adjustable storage duration), shows test outcomes in real time, and generates reports. It can be connected to a printer to output test reports, and its data is saved in the standard Excel format, enabling compatibility with other software applications.
