Caravan Experts Take You Through Those Secrets Of Caravan Air Conditioner
1. Classification of RV air conditioners
(1) Driving air conditioner
It is the air conditioner used when the vehicle is driving, and the air conditioner used when the original vehicle engine is started. Generally, when the car is parked, the driving air conditioner cannot be used for a long time, otherwise it will cause the carbon monoxide concentration in the car to exceed the standard and cause suffocation. In addition, the cooling effect of the driving air conditioner is also very unsatisfactory when idling.
To ensure the cooling effect, generally a 5-meter RV is equipped with a driving air conditioner with a cooling capacity of 4,000 to 5,000 calories; for a RV with a length of 5.5 to 6 meters, when the cockpit and the passenger compartment are connected, the original car manufacturer generally They will all be equipped with "rear air conditioning evaporator: only when the cooling capacity reaches 8,000 to 10,000 kcal, the cooling capacity will be guaranteed.
(2) Parking air conditioner
Parking air conditioners are mainly car air conditioners used for parking. This type of air conditioner is generally installed on the top of the vehicle. The internal unit is on the top of the car and the outdoor unit is on the top of the outside of the car, so it is also called a roof-mounted air conditioner. Generally, the parking roof air conditioner increases the height of the RV by 23~30cm, so a few manufacturers install it under the seat. Since it does not need to change the appearance of the car, it is more suitable for friends who make personal modifications.
Parking air conditioners are generally divided into heating and cooling and single cooling air conditioners. RVs with a length of more than 5 meters generally choose heating and cooling air conditioners.
2. RV air conditioning Q&A area
(1) Q: Can a household air conditioning compressor be used in the original car air conditioning pipeline?
A: No. Household air conditioners use high-pressure copper tubes and copper tube evaporators and condensers; automotive air conditioners use rubber tubes and aluminum evaporator condensers. Pipes will burst.
(2) Q: Home inverter air conditioners are cheap and energy-saving. Can they be used on RVs?
A: Many car enthusiasts have made modifications when DIYing, but it is not recommended to do it in mass-produced RVs, because the design premise of household air conditioners is to be fixed, and vehicles are moving and bumpy, and the earthquake resistance level of household air conditioners is not designed to meet the requirements. Due to the requirements of vehicle driving and long-term use, the components of the air conditioner will loosen and deform during vehicle driving, causing hidden dangers to the user's safety.
(3) Q: What are the cooling and heating powers of the parking air conditioner? And what size of generator is suitable?
A: Single refrigeration air conditioner: the refrigeration power is generally around 1000W, which can be matched with a 1600W generator;
Hot and cold air conditioners: The heating power is about 2200W, the power when cooling is started is also 2300W, the cooling start time is about 10 minutes, and the power when cooling is running is 1200W. The generator that needs to match the 2200W power of the hot and cold air conditioner needs to be 2600W-3000W.
(4) Q: How to cool down without a generator?
A: 1. When the RV is parked, try to choose a safe place that can connect to the mains electricity, such as a canteen or near a farmer's house. Say a few polite words, pay some money, and connect the electricity;
2. If you go to a relatively wild place where there is no way to connect to electricity and you don't bring a generator, you can choose to use a micro fan to cool down.
