Product Name
PV humidity-freeze test chamber | solar PV module humidity-freeze test chamber
Application
The PV humidity-freeze test chamber is suitable for thermal cycling, humidity-freeze cycling and high-temperature high-humidity double-85 tests of PV modules (solar panels), to confirm whether the modules can withstand the subsequent negative-temperature effects after high temperature and high humidity, and the fatigue and thermal failure caused by repeated temperature changes; and to determine the thermal stress generated when PV modules are exposed to high humidity and their ability to resist long-term moisture penetration. It is essential test equipment for the PV module industry.
Control System
- Controller: true-color 7.0-inch TFT LCD touch-screen controller with Chinese/English display. For program setting, only the temperature and time parameters need to be set, without extra commands to start the compressor, etc.
- Program capacity: 1,000 program memories, each with 1,000 steps and 100 cycles, and a linking function for 10 programs.
- Communication interface: 1 USB port and 1 LAN port, allowing monitoring of the test process and functions such as automatic start/stop.
- Control mode: PID auto-tuning and FUZZY control, with data acquisition, export and graph viewing functions.
Refrigeration System
- Compressor: the refrigerator uses French Tecumseh fully hermetic compressors. (The compressor is automatically controlled in segments by temperature high/low points to reduce energy consumption and extend compressor service life.)
- Refrigerant: non-fluorocarbon environmentally friendly refrigerant (US DuPont R-404A, R23).
- Condenser: water-cooled shell-and-tube type (cooling tower and its system are provided and installed by the customer).
- Evaporator: fin-type multi-stage with automatic load capacity adjustment.
- Expansion system: refrigeration system with solenoid valve + expansion valve capacity control.
Standards
PV module IEC 61646 test methods:
- a. Thermal cycling test: (Purpose: to determine the ability of modules to withstand thermal mismatch, fatigue and various stresses caused by repeated temperature changes.) Cycle the modules between -40°C±2°C and +85°C±2°C. The temperature change between the maximum and minimum temperatures shall not exceed 100°C/h.
- b. Humidity-freeze test: (Purpose: to determine the ability of modules to withstand high temperature and high humidity followed by sub-zero temperatures.) Change the temperature between +85°C and 25°C at a rate not exceeding 100°C/h, and between 25°C and -40°C at a rate not exceeding 200°C/h.
- c. Damp-heat test: (Purpose: to determine the ability of modules to withstand long-term moisture penetration.) Test temperature: 85°C±2°C; test humidity: 85%±5%; test duration: 1,000 h.
