The battery capacity, the new and old batteries directly affect the length of time the air conditioner can be used.
Now take a new 180AH battery as an example to roughly calculate the amount of electricity this battery can use for truck air conditioning.
Calculation of battery capacity: total power=180AH*24V=4320AVH=4.32kWh.
Calculation of the electricity available for truck air conditioning :
Available electricity = total electricity-car startup electricity = 4.32 (1--25%) = 3.24 kilowatt-hours of electricity.
If the storage capacity of the old battery is calculated at a loss of 20% per year, the usable capacity of the battery after 1 year of use can be roughly calculated as follows :
Available power = total power * 0.8-total power * 0.25 = 4.32 * 0.8-4.32 * 0.25 = 2.37 kWh
Power consumption of Truck Cab Air Conditioner :
The power consumption of the Truck Cab Air Conditioner changes dynamically. In order to accurately calibrate the power of the Truck Cab Air Conditioner , the country has a standard for the car air conditioner: the rated power consumption of the air conditioner refers to the internal temperature of 60.8 degrees Fahrenheit and the outside temperature of 100.4 degrees Fahrenheit (there are other conditions Limit) the power consumption of the air-conditioning operation. The measured power consumption of Coolpro Truck Cab AC under the above conditions is 830W (power consumption per hour is 0.83 degrees). Regardless of the influence of other factors, the calculation of the use time of the Truck Cab AC at 100.4 degrees Fahrenheit outside the car and 60.8 degrees Fahrenheit inside the car:
The new 180AH battery:
Use time = available power / air conditioner rated power consumption = 3.24/0.83 = 3.9 hours
180AH battery used for 1 year:
Use time = available power / air conditioner rated power consumption = 2.37/0.83 = 2.85 hours
The difference between good and bad Truck Cab AC : general common sense inverter air conditioners are more energy-efficient than fixed frequency air conditioners.
Nowadays, different brands of truck cab air conditioners on the market have a big difference due to factors such as technical strength. Under the premise of the same cooling capacity, rough statistics of good brand inverter air conditioners Compared with poor brand air conditioners, the input power of good air conditioners can be reduced by 20%.
Vehicle:
The factors of the vehicle include: the environment where the vehicle is located, the quality of the vehicle's thermal insulation, and the user's habit of using air conditioning.
The environment of the vehicle means that the lower the temperature inside and outside the vehicle when the Truck Cab AC is used, the longer the Truck Cab AC will be used. On the contrary, the higher the temperature inside and outside the vehicle when the Truck Cab AC is used, the shorter the time the Truck Cab AC will be used.
The thermal insulation of the vehicle is good or bad: the longer the Truck Cab AC with good thermal insulation is used, the shorter the use time of the Truck Cab AC with poor thermal insulation. In layman's terms: a car parked in the shade of a tree lasts much longer than an Truck Cab AC parked in the sun; a car with a heat-insulating sunshade on the glass in the car can last much longer than a Truck Cab AC without.
The higher the temperature of the Truck Cab AC set by the user, the longer the use time of the Truck Cab AC; the lower the temperature set the Truck Cab AC, the shorter the use time of the Truck Cab AC. For example, the user's Truck Cab AC set temperature is 78.8 degrees Fahrenheit. When the Truck Cab ACr reaches the set temperature, the Truck Cab AC compressor will stop running. At this time, the power consumption of the Truck Cab AC may be only 100W, which means that the power consumption per hour is only 0.1 kWh. If the user's air conditioner set temperature is 60.8 degrees Fahrenheit, the air conditioner compressor may run at high speed for a long time, and the temperature inside and outside the car is under very high conditions, the air conditioner may reach 1100W or higher at this time. Power consumption, so the power consumption per hour is as high as 1.1 degrees or more.
Specifically, what is the relative data of the above-mentioned factors on the length of air-conditioning use time, as a professional air-conditioning manufacturer, it is not possible to give accurate data.
If the owner of the Truck Cab AC makes full use of the above factors to increase the battery power, reduce the power consumption of the Truck Cab AC, and improve the Truck Cab AC environment: “Coolpro Truck Cab AC uses 3 to 4 hours during the day and 8 to 10 hours at night" is a common reality.
