24V-12V RV and Truck Parking Cooler DR3

1. What's parking air conditioner?

 

Parking air conditioning (also known as parking cooler/ electric cabinet air conditioner) refers to battery powered air conditioner, consuming electricity from the vehicle battery (DC 12V/24V/36V/48V/60V/72V) instead of taking power from engine. It’s normally used in vehicle parking to control the temperature, humidity, flow rate to create a comfortable environment for drivers.

 

Parking air conditioner is widely used for trucks, construction machinery, campers, motorhomes, and other confined spaces. Compared with traditional vehicle air conditioners, parking air conditioners do not need to rely on vehicle engine power, which can save fuel and reduce environmental pollution.

 

Parking air conditioners are mainly for single-cooling, constituted of condenser, evaporator, electronic control system, compressor, fan and piping and others parts. For rooftop air conditioners, refrigerant HFC134a/R410A is prefilled in the air conditioning system. For split parking air conditioners, prefilled and un-prefilled types are for option.

 

Parking air conditioners are divided into rooftop air conditioners, split/backpacks air conditioners, and hidden and parallel air conditioning systems. While rooftop air conditioners require cutting the ceiling, for customers who cannot accept this situation, clients prefer split air conditioners.

 

To avoid vehicle not starting due to low battery power, all parking air conditioners are equipped with low-voltage/high-voltage protection, current overload protection and other protection functions. If there is any problem with the air conditioning system, the corresponding error code will show on the screen. According to the error code, the error code explanation and solution will be provided in the manual, which makes air conditioner repairment easier. The error code definitions for each model are different, so clients need to refer to different instructions.

 

2. Specifications for 24V Truck 12V RV Parking Cooler DR3

 

24V Truck 12V RV Parking Cooler DR3 was launched in 2024. It's with scroll compressor, double size aluminum condenser and evaporator. It's with 4 adjustable cold air outlet holes. For 24V, 48V, 60V and 72V types, it can be with both cooling and heating functions.

24V Truck 12V RV Parking Cooler DR3 was designed according to market feedback in the past few years. 4 cold air vents type is more acceptable by customers becuase it's easy to handle, so this design was kept. When market demands stronger cooling capacity, we adjusted the previous model and upgraded it with double fans to provide more air flow. To make the refrigerant circulation faster, we make the condenser 2 times big as before. Also for some heavy machinery users, they require 48V-72V air conditioning system, and we make this model with 48V-72V version. Besides, for 24V, 48V-72V types, both heating and cooling AC is avaible.

3. Notes for using parking air conditioners

In using parking air conditioner, please follow the instructions as below:

 

To set the air-conditioning temperature within a suitable range. Low temperature not only easily causes physical discomfort, but also increases energy consumption.

 

To choose proper operation mode: Parking air conditioners are with eco mode, sleep mode and strong mode. Clients can choose the appropriate mode according to their needs.

5. Installation Instructions

 

* Clean the surrounding area of the skylight to ensure that there is no debris, dust and concave and convex deformation.

* sunroof, the paste high elastic sealing sponge article (article sponge than skylight uplift side) - the high elasticity sponge article according to the days out of the window profile against (skylight on sealing sponge to level off, do not have crack, incomplete, deformation, wrinkling, etc., affect the sealing of air conditioning host and skylight otherwise cause air leakage, water leakage, and so on and so forth.)

* Put a circle of glass glue on the surface of the high elastic sponge strip. (I suggest typing more)

* air conditioning machine part (including four fixed screws) into the skylight, adjust the front, back, left, right position, with decorative plate than, make decorative plate installed can cover the air conditioning outlet outside the other internal exposed position.

* the use of pull lining fixed air conditioning host (fixed torque can not be too large, too large will cause deformation of air conditioning floor, air conditioning drainage failure, serious will lead to air conditioning water leakage.) . After the main air conditioner is fixed, check whether the glass glue between the bottom plate of the air conditioner and the high elastic sealing sponge overflows in the whole circle from the car. If the glass glue overflows in the whole circle, it proves that the seal is intact, otherwise it needs to fill the glue. Finally install the decorative plate.

* connect the cable to the battery 48V or 60V or 72V (voltage V number varies according to different models, positive and negative poles shall not be connected, otherwise it will cause air conditioning damage!)

Note again: when fixing the lining strip, the torque should not be too large, as long as the glass glue between the base plate of the air conditioner and the high elastic sponge strip overflows in full circle.

 

Attention: Refrigerant oil is filled in the rooftop/split air conditioner before delivery. After first time installation, do not fill more refrigerant. In case of any refrigerant leakage in using the parking air conditioner, add 80ml refrigerant oil POE68 again. The refrigerant oil must be of high quality.

6. How to maintain parking air conditioner?

 

Before cleaning it, make sure the air conditioner is turned off, powered off and unplugged.

 

* To clean indoor unit evaporator surface:

Wash the cleaning cloth in clean water, dry it and wipe the surface of the unit. The cloth can be dipped in the water solution of neutral cleaner.

 

* To clean the core of evaporation tank:

Remove the indoor unit case and blow off the dust on the surface with compressed air.

 

* To clean outdoor unit:

Remove the unit case and clean the condenser with compressed air. Avoid any bump against the condenser.

If you don’t use the parking air conditioner for a long time, unplug the air conditioner and wrap the outdoor unit and avoid any bump

 

* To use the parking air conditioner after long-time storage:

Clean the unit body, condenser, and evaporation unit; check if there is foreign matter at the air inlet/outlet of the indoor and outdoor unit; check if the drain pipe is clear; put batteries in the remote control; make inspection and power it on.

 

Tips:

Clean the air conditioner once every month. If there is too much dust in the working environment, increase the cleaning frequency accordingly. Please make regular cleaning to make sure it can run normally.

 

7. RFQ

 

● How many hours will the parking air conditioner work?

For scroll compressor type, sleep mode power consumption is 600W, strong mode power consumption is 800-1000W. For rotor compressor, sleep mode power consumption is 400W, strong mode power consumption is 700-800W. For example, 24V 400Ah battery, scroll compressor parking air conditioner will last 10-12 hours, and rotor compressor parking air conditioner will last 14-16 hours.

 

● Do I need to buy other parts after I receive the parking air conditioner?

It’s a whole package with all parts needed. For rooftop parking air conditioners, Freon is prefilled, so all you need to do is install and connect it to battery. For split air conditioners without Freon, all you need to do is ask a mechanic to install and fill Freon at suggested amount.
