Programmable constant temperature and humidity test chamber refrigeration system: 1. The refrigeration machine adopts a fully enclosed French Taikang (or semi enclosed German Gulun) compressor. 2. The refrigeration system adopts a unit or binary low-temperature circuit system design. Adopting air-cooled single machine compression/air-cooled stacked compression refrigeration method

Humidification and dehumidification system: 1. Humidification: External isolated all stainless steel shallow surface evaporative humidifier, which forms wet vapor humidification through heating and detects humidity through a probe. 2. Dehumidification: Adopt evaporator coil dew point temperature laminar contact dehumidification method. 3. Water supply: Hidden water tank for water supply, small water pump automatically draws water to the humidification tank, and can recycle residual water Water conservation and consumption reduction.

Heating system: 1. Finned heat dissipation tube shaped nickel chromium alloy stainless steel electric heater. The independent cooling, circulation, humidification, dehumidification, and heating systems can improve efficiency, reduce testing costs, increase lifespan, and reduce failure rates.

Temperature and humidity controller: LCD touch screen programmable controller, in both Chinese and English, with high contrast and adjustable backlight function LCD display controller.

Wind circulation system: 1. Adopting a multi wing centrifugal fan for strong air circulation to avoid any dead corners and ensure even temperature and humidity distribution in the testing area. 2. The design of air circulation for air outlet and return ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature and humidity at the moment of opening the door. 3. Use adjustable air deflectors that can be adjusted up, down, left, and right to ensure even distribution of temperature and humidity.

Introduction to Programmable Constant Temperature and Humidity Test ChamberAdopting a high-precision microcomputer touch based temperature and humidity controller, coupled with a high stability platinum temperature measurement antibody and a wind speed circulation system for temperature sensitivity testing, to achieve uniform, accurate, and stable temperature and humidity control. There are also independent heating, cooling, humidification, and dehumidification systems that can be used for different environmental tests such as high temperature, low temperature, and constant temperature and humidity.
