What is the current refrigerant used in air conditioners?
1 Answers
Currently, air conditioners use R22 Freon refrigerant and R410 environmentally friendly refrigerant. Common knowledge for air conditioner maintenance and cleaning is as follows: 1. Pre-operation maintenance: Typically, household air conditioners are turned off after September and not used again until May or June of the following year, remaining idle for over half a year. Therefore, a comprehensive inspection must be conducted before turning on the air conditioner to check for any issues. Based on the inspection results, and under the guidance of professional technicians, thorough maintenance and cleaning should be performed, covering the exterior shell, body, and filter screens of both the outdoor and indoor units. After this, a trial operation should be conducted to observe the cooling speed and effectiveness. 2. Maintenance during operation: After the air conditioner is turned on, the frequency of maintenance depends on various factors such as environmental conditions, climate, operating hours, surrounding dust levels, air cleanliness, and the cleanliness of the room. Poor environmental conditions, hot weather, older air conditioners, and extended operating hours will increase the need for maintenance, typically once every month and a half. If environmental conditions are good, the air conditioner is relatively new, dust levels are low, and the air conditioner is used reasonably—alternating with electric fans—the maintenance cycle can be appropriately extended, requiring only 1–2 maintenance sessions from startup to shutdown. Maintenance should be thorough and meticulous, leaving no dead spots, to ensure compliance with standards, improve cooling speed and effectiveness, and achieve energy efficiency, freshness, and comfort. 3. Post-operation maintenance: As the weather warms up, air conditioners are turned on, and as it cools down, they are turned off—this is a perennial pattern. Before shutting down the air conditioner, a comprehensive and careful inspection of both the outdoor and indoor units should be conducted. For high-quality split units and cabinet units from well-known brands, special attention should be given to ensure optimal energy-saving performance.
