The general rule for all users of air conditioners is to disable the device at a temperature of less than - 5 ° C. Neglecting to do so could lead to premature failure of the device due to the structural features are not designed to work in cold weather. To overcome this drawback of the device to increase efficiency on the air conditioner must be installed winter set to operate at cold weather.
Contrary to popular belief, this kit does not turn the air conditioner in the room heating device. Its positive effect is to remove the restriction on the cooling operation at low temperatures. This is true for industrial premises, where even during the cold season accumulates excess heat, but is limited by the possibility of airing. Standard winter kit consists of three main elements:
Mounted on the air conditioner winter kit allows you to operate it in the winter and does not allow the emergence of common problems in these conditions:
- reduction in productivity;
- increasing the length of the transition mode;
- appearance of the refrigerant in the compressor crankcase;
- inclusion in cold weather;
- drainage blockage.
Acquired such equipment:
- separately;
- with split system;
- piecemeal.
installation Procedure
Winter kit is mounted on the external unit. This allows to use a conditioner for cooling a cold (up to - 30 ° C).
To connect the set to an external module you must dismantle it, remove the outer and the side cover, front panel. You can then move on to the connection:
- Heating device crankcase of the compressor;
- temperature sensor with connecting it to the fan;
- cable for heating the drainage tube.
Upon completion of all connections earlier removed elements of the housing back in place and the unit is placed on the brackets.
Installation of the compressor crankcase heater
Due to the heater of the oil bath temperature is higher than the heat exchanger, which prevents the oil mixed with freon. It is located in cooler parts of the design and when starting does not take away from an oil. This provides the necessary lubrication when the air conditioner starts to operate and saves his working life. The location of the heating of the lower part of the compressor where lubricant is going to idle apparatus.
Connecting the controller
Retarder controller or reduces air flow through the condensing unit portion. This prevents freezing of radiator grilles, ice formation and hypothermia devices. Retarder consists of:
- Sensitive sensor which picks up the temperature of the heat exchanger.
- Variator determines the fan speed and temperature of condensation.
Sensor
It begins with the installation of the moderator with the sensor. To do this:
- select medium heat exchanger coil located between the inlet and outlet tubes;
- mounted on the sensor therein;
- process thermal paste;
- thermal insulation of flex.
This setup protects the sensor from the effects of external factors and provide better contact with the heat exchanger.
Variable speed drive
Installing the controller is carried out by an external module wiring diagram and connect the retarder.
When reading regulator circuit note the difference in connecting the single-speed and multispeed fans.
According to the scheme (Fig. 1) connect:
- yellow regulator input cable to the respective terminal of the fan;
- regular orange connect wire with a black output regulator.
When multi-speed fan (Fig. 2):
- Yellow input to the sensor cable are placed all fan speeds;
- on black connects the maximum speed.
If the heating mode is present, include its wire to the terminal according to the scheme without isolating and fastened on the housing. At times fasten the remaining wires (blue, brown), heating wire, power is supplied to them.
Drainage installation of heating cable
This cable is needed if drainage displayed outside. heating wire drainage tube supports required temperature to prevent ice plugs and inward penetration condensate system with its output down. There are two types of wires heats:
- with internal mounting in a drainage tube cavity;
- with the outside, reaching the surface of the pipe.
To install the wires necessary to:
- seal the ends to create a robust waterproof insulation;
- plastic clamps to fix it to the drain pipe;
- connected to a terminal on the external power supply unit.
If no such terminals need an additional power supply cable, which is held on the indoor unit together with the inter wiring.
After performing the installation work all the elements are returned to their original location, and checks the operation of additional equipment:
- fan speed;
- heating functionality;
- the pressure in the condenser.
In normal operation of the device can proceed to the daily operation of the improved split-systems.
