Aircooler and dehumidifier

For profund training in air-conditioning it is necessary to understand the processes aircooling and airheating. Aircooling is a precondition for dehumidifying and airheating a precondition for humidifying. These physical facts base on the effect that air absorbs the more water the higher is its temperature . Exceeding the limits effects condensate or rain. TeLC has designed two units to do training in these subjects. Both devices can be used combined or isolated. The above photo shows the aircooler.

Systems:

Aircooled evaporator
Aircooled condenser
Speed control of both axial fans
Manometers for liquid and vapor pressure
Wattmeter for the compressor electric power consumption
Turnflap for the reheating using the compressor heat dissipation

Measuring systems:

The unit can be equipped with electronic sensors digitally connected to the internal controller, sending serial data to an external PC. Stand control and data acquisition is performed by Windows-software. Measured quantities are:

Volume measurement of the dehumidifying (condensate)
Dry bulb temperature 0-120°C
Relative humidity, humidity ratio

Details:

Benchtop unit 2m x 0.5m x 1.1m
Weight: 63kg

The above photo shows the combined build-up. The airheater unit on the right is blowing into the aircooler unit on the left.

Systems:

Steam generator with drowned electrodes
Processor- and selfcontrolled system with fast reaction on steam-requests
Overtemperature and airflow safety system
Axial fan with continous speed control
Removable steam mixing channel
Transparent channel side wall
3-stage low temperature heating system

Measuring systems:

Dry bulb temperature 0-120°C
Relative humidity, humidity ratio

Aircondition test stand

Aircondition unit in industrial segmented design with modern steam humidifying, cold water coolers / dehumidifiers and detailed measuring devices. Wide range of airtreatment through combination of 2 treating units: One for the production of the environmental condition, the second for the conditioning of the entry situation. The entry situation is independant from the room or the outside climate. The two conditioners contain the same treating equipment. The cold water generator for the cooling exists only once for the sharing or concentrated cooling only in the one or the other part. The cold water unit is very practical for the reversing and the measuring. Additional equipment like air mixing section or cooling tower are possible, also reduction of equipment.

Measuring and control systems:

All equipment is of industrial standard and grant for high efficiency, long life and little maintenance. Heaters, fan, humidifiers and valves are controlled by PC and touch-screen.
The measuring devices are digitally connected to the internal controller, sending serial data to the comprised portable PC. Stand control and data acquisition is performed by Windows-software. Measured quantities are:

Dry bulb temperature 0-120°C
Relative humidity, humidity rati
Volume and mass flow rates
Volume measurement of the condensate/ rain

Technical details:

Channel cross section size:	0.5m x 0.5m
Dimensions:	5.0m x 1.0m x 1.8m
Weight:	600 kg
Services:	400 V 3-ph. AC, cold water
