General Specifications

TEKNOPOOL units are designed by R&D Department in 8 models for pools with water surface between 50m2-500m2. They used for dehumidification process of the pools. They come with automation panel. Thereby, the cost for installation and operation will be minimized thanks to plug and play design. It consist of three sections, Fan, Heat Recovery and Dehumidification.

Fan Section

The return air goes into dehumidification process and comes to Fan section. Fan section blows dehudified air back to pool area. There are three different types of application in this secton; Belt driven, Plug fan and EC Plug fan.

Heat Recovery Section

Two types of heat recovery systems are available with TEKNOPOOL units; Heat Pipe and Plate Type.It is possible to consume less energy while reaching higher dehumidification values by using heat recovery systems in swimming pool air handling units.

Dehumidification section

TEKNOPOOL units have two types of dehumudification systems; In heat recovery systems and with mechanical cooling. R407C refrigerant is used in mechanical cooling systems. The components of the systems are; compressor,condenser, evaporator,expansion valve,dryer,selenoid valve,suction accumulator, liquid tank . High performance scroll compressors are preferred in this system.

Components

Body

The body of TEKNOPOOL units consist of eloxal coated corrosion resistant aluminium profiles . The panels are produced with special gasketing to prevent any contact between inner and outer sheet metals. The 50mm panels which has 70kg/m3 rockwool in density . The sheet metal which is 275gr/m2 galvanised coated and RAL9002 coated is used as standard component for all sheet metal applications.Thereby TEKNOPOOL units offer corrosion resistance.

Compressor

High performance Scroll compressors are used in TEKNOPOOL units. Cooling chamber and compressor are designed at the same cell . This design offers easy start up of the unit. R407C refrigerant is used in the system.Pressure sensors at the suction and forcing side saves compressor and the system.

Evaporator

Direct expansion exchangers are used in TEKNOPOOL units for dehumidification of return air. The surface of the evaporators are hydrophilic coated. The body is epoxy painted.

Drain System

Due to high condensation,TEKNOPOOL Units has a safe,easy and fast drain system to discharge water from the system. The drain pan designed by R&d department of TEKNOGEN is made up of stainless steel and it collects water to a single point and discharge water immediately. Syphon is a standard application in all TEKNOPOOL units and it easily removes drain to water network.

Components

Fan/Motor

Three types of fan applications are possible in TEKNOPOOL units; belt driven,Plug Fan,EC Plug Fan.

Condenser

The refrigerant gas is vaporised during cooling process of air and it condensates(turns to liqid) again in condenser.

Heat recovery

Two types of heat recovery systems are available with TEKNOPOOL units; Heat Pipe and Plate Type. Both systems work on same principle. Thye produce energy efficiency through bringing condenser and evaporator inlet air temperatures to optimum working conditions by using energy coming form dehumidifiated return air.

Filter

G4 Panel filters are standard in TEKNOPOOL units on fresh air and return air directions. M5, M6, F7, F8, F9 bag filters are optional.

5

Automation

TEKNOPOOLunits are produced with full automation control system. All scenarios are defined in automation system which lets the user have plug and play unit. Thereby , start procedure will be very easy after duct,drain and power connections. There are four different scenarios for dehumidification prcess in TEKNOPOOL units;

Winter(Night)-Dehumidification On

This scenario is active during non-common usage of the pool. The unit works with %100 fresh air. The cooling chamber works and dehumidification is on.

Winter(Night)-Dehumidification Off

This scenario is active if pool is not used. The unit works with %100 fresh air. The cooling chamber does not work and dehumidification is off.The heater is on.

Winter(Day)-Dehumidification On

This scenario is active during common usage of the pool. The unit works with %75 fresh air and %25 return air. The cooling chamber Works and dehumidification is on. The heater will start if it is needed. This is the scenario that the unit works with full capacity.

SummerThis scenario is active if outer and inner temperaturs are close to each other.The unit works with %100 fresh air. The cooling chamber does not work . The heater will start if it is needed.

Components Used for Automation

• Humidity and temperature sensors• Differential Pressure sensor• Frequncy converters(In Plug Fan Applications)• Damper Motor(Proportionally Controlled)• Low/High Pressure Controls for Compressor• MCC Board• DDC Board

Automation System

TEKNOPOOL units specially designed automation cards. This card can control ,blowing and suction fans, safety of cooling chamber, damper on the unit,constant flow of the fans. The control panel could be connected till 200m . away from the unit. Weekly programming, filter dirtiness alarm, operation and fault signals are available.
