DL compressors

Compressor Overview

Technical specification
Many vehicles for transportation of goods or recreation, such as trucks, caravans, boats, cars, etc. are often equipped with cooling appliances.
These compressors are designed to operate silently, efficiently and reliably even up to angles
of tilt of 30º, working with refrigerant R134a. The compressors for such mobile applications must be designed to operate from a low voltage DC power supply. These compressors must also be compact in their dimensions, highly reliable and yield high performances.
The DL series of compressors are not designed for
off-road applications. Special approval is required
by Danfoss Commercial Compressors for this type
of application. The maximum tilt angle allowed in
DL compressors (stopped or running) is 30º. DL19H, DL22H and DL30H are the answer to the users’ needs requiring comfort and reliability in their travelling, either on holidays, at work or in any other circumstance where Direct current is

General rules and wiring connections

Voltage drop in the power leads

DL series must always be powered through the dedicated electronic driver, which is supplied with the compressor as a separate device.
• Never connect the compressor’s hermetic pins (fusite) to the terminals of a battery or any other dc or ac source directly.
• Do not try to fit an electronic driver different than the electronic driver supplied with the compressor. the compressor will not operate and irreversible damage may occur.
the power input terminals of the electronic driver
• “-“ Power input terminal of the electronic driver should be connected to the chassis of the vehicle as well as the appliance frame
• A fuse must be placed between the “+” pole of the battery or dc power supply and the “+” power input terminal of the electronic driver:
- 12V systems: 12A fuse
- 24V systems: 7.5A fuse
• Always respect the polarity of the battery with
To avoid excessive voltage drop in the leads, their length and cross section must be related to the voltage supply as indicated in Table below.

* The positive side of the fan is connected to the (F +) end of the controller, and the negative terminal of the controller is connected to the (F-) terminal of the controller. A terminal of the controller (F +) and (F-) can be connected with a 12V DC fan The When the input voltage of the controller exceeds 12V, the output value between the terminals (F +) and (F-) is always kept at 12V.
Regardless of whether the input voltage system is 12V or 24V, the fan must be a 12V DC fan. B, the controller can continue to output 0.5A fan drive capability.

There is a protection system for the battery that prevents the compressor from operating if the available voltage becomes too low. The electronic driver will start and stop the compressor as needed by detection of the voltage between the input terminals (+) and (-) to protect the different power supply batteries.

Temperature Switch

The recommended standard battery protection values are listed in table 6. Other voltage can be set by adjusting the controller terminal (C) and (P) connection resistance (9), the specific value of Table 5.

• The controller terminal (+) and (D) can be connected between a 10mA LED (6) for the display fault, LED anode connected to the controller (+) side, the cathode connected to the controller (D) end.
• When the failure occurs, LED every 3 seconds for the cycle, continuous flash in each cycle, according to different failures flash different times, each flashing for 0.4 seconds, continuous flashing for 3.2 minutes. The number of specific codes and blinks is shown in Table 8.
