ZM6158 Split System Air Conditioner Refrigeration Training
Equipment Teaching Equipment
1. Overview
* Modern air conditioning unit with heat pump function: cooling and
heating1
* 6 different operating modes
2. Technical Description
Split system air conditioners are used to cool, dehumidify and also
heat
rooms. The consist of an inner and outer unit.
In the inner unit there is a heat exchanger with fan working as an
evaporator in the refrigeration circuit during cooling operation.
During heating operation it works as a condenser. The outer unit
contains a compressor, another heat exchanger, expansion element
(e.g. Capillary tube) and an element enabling the change-over from
cooling to heating operation. In cooling operation the evaporating
refrigerant in the heat exchanger of the inner unit withdraws heat
from the room air. In the outer unit the heat in the heat exchanger
is discharged to the ambient air by condensing the refrigerant.
During heating operation the heat transport is Reversed.
It includes a dividing wall onto whose front and rear panel a
modern split system air conditioner has been mounted. To better
demonstrate its operation, an additional two pressure displays are
available for the refrigerant. The operating mode, fan stage of the
inner unit (fan operation) and desired room temperature are
selected via a remote control. During automatic operation the
actual room temperature is recorded and an operating mode
automatically selected to achieve the specified room temperature.
In addition the following functions are set at the remote control:
Timer
for the regular switching on and off, single remaining operating
time in
hours (sleep mode; suitable for energy-saving operation) and
horizontal
position of the lamella at the air outlet for air distribution
(swing mode;
fixed or movable).
3. Learning Objectives / Experiments
- design and operation of a split system air conditioner
- 6 operating modes
* cooling
* dehumidifying (slight cooling)
* heating
* ventilation (only the fan of the inner unit)
* automatic (operating mode suitable for the room temperature)
* test of cooling function
- 3 additional functions
* "sleep" (switch-off after several hours)
* "swing" (air outlet lamella position)
* timer for switching on and off
- remote control functions
