Regardless of the on-vehicle air conditioner and the parking air conditioner, the RV is composed of compressors, condensers, evaporators, controllers, refrigerants, etc., and the principles are basically similar.
Parking air conditioner: the compressor works by electric power, which is an electric compressor;
On-vehicle air conditioner: It is a mechanical compressor that relies on a car engine to drive a compressor. The following is the specific cooling method:
1. Mobile air conditioner
Advantages: low price, and some air-conditioning parameters have a large cooling capacity. It is portable and easy to install, and it can be used at home when the RV is not in use.
Disadvantages: Since the mobile air conditioner compressor is built-in, the operating noise is higher than that of the ordinary wall-mounted air conditioner. Mobile air conditioners have the disadvantage of costing electricity, and mobile air conditioners with high cooling capacity take up too much space.
2. Air-conditioning fans with ice, fans, circulating fans
Advantages: The price is cheaper, and it is cooled by adding ice, the principle is different from that of the air-conditioning compressor. The ice-filled air-conditioning fan is similar to the rural water air-conditioning. It saves electricity, only a blower has a power of tens of watts, and has the function of heating and humidifying in winter.
Disadvantages: The humidity is relatively high, and it is said that it is only cool where the cold wind blows.
3. The original car parallel electric air conditioner
Advantages: Shared evaporator and condenser, cheap, and save space.
Disadvantages: a certain amount of hands-on ability is required. Trucks are used more often because of low cooling capacity and low energy efficiency, rather than installation technical problems.
4.DC air conditioner
Advantages: Save the inverter, save the cost,
Disadvantages: Although major manufacturers have invested in research and development, there is still a gap between the research and development of tens of thousands of household air conditioners and the investment of hundreds of millions of yuan, and the price is expensive.
5. Household air conditioners
Advantages: cheap and affordable, large cooling capacity, and quiet and energy-saving.
Disadvantages: It takes up too much space and is not developed for RVs. The secondary accidents that may be caused by using on RVs are not covered by insurance.
Actual RV riders use a lot of home air conditioners. They are easy to install, and the external machine is damped, and the air inlet and outlet are reserved. Here is a reminder that the R32 refrigerant is flammable and explosive.
6.Dedicated overhead air conditioner for RV
Advantages: Many domestic and foreign brands of dedicated top-mounted air conditioners for RVs, foreign brands have passed more than 100 years of testing and testing, and they have good reliability and save RV space.
Disadvantages: With the price reduction of solar photovoltaic panels, from 40 yuan a watt in the early years to less than 3 yuan a watt now, overhead air conditioners occupy the position of photovoltaic panels, and those flashy range hoods also occupy photovoltaics Board position.
7.Bottom-mounted air conditioner for RV
Advantages: small size, hidden installation does not take up space; flexible installation methods; very low noise; comfortable air-conditioning; modular structure, the easiest maintenance.
