What Are the Reasons for Poor Air Conditioning Cooling in New Energy Vehicles?
1 Answers
New energy vehicle air conditioning may not cool properly due to insufficient or too little refrigerant, or minor refrigerant leakage. Excessive refrigerant can also cause the air conditioning to not cool; because there is a required proportion of refrigerant volume in the air conditioning system. Solutions for insufficient or too little refrigerant: 1. It can be observed from the sight glass on the top of the dryer. During normal operation of the air conditioning, if there are continuous, slow bubbles in the sight glass, it indicates insufficient refrigerant. 2. If obvious bubble flipping occurs, it indicates severe refrigerant shortage. 3. If the refrigerant is insufficient or too little, the solution is to add refrigerant. However, it should be noted that if adding from the low-pressure side, the refrigerant bottle must not be inverted; if adding from the high-pressure side, the engine must not be started.
