Technology overview – Compressor

Toshiba DC-inverter compressors, Twin-rotary

for the larger sizes (all but size 4kW), for improved reliability,

smooth and vibrations-free operation, from 20 up to 120%

of their nominal capacity.

AIR HP DC inverter uses IPDU hybrid inverter technology, combining PAM + PWM for optimized compressors operations in all conditions, minimized temperature fluctuations and providing perfect comfort with significant reduced energy consumption


AIR HP


Technology overview – Compressor

LESS VIBRATIONS MAKE THE LIFE OF THE COMPONENT LONGER, WHILE ENSURING REDUCED NOISE


AIR HP


AIR HP combines two electronic management logic control systems

PAM : Pulse Amplitude Modulation

Goal: maximum power at the start up and in peak load conditions

Benefit: fast reach of the set point (desired temperature)

How: frequency is fixed and voltage is increased. Compressor works at high

speed to rapidly achieve the set point

When: in max load conditions

Result: HIGH POWER

PWM : Pulse Width Modulation

Goal: maximum efficiency and comfort

Benefits: energy saving + no temperature fluctuation once obtained the set

temperature

How: load voltage is fixed and frequency is varied to fine tune compressor speed

When: in partial load conditions

Result: HIGH EFFICIENCY

Sensors

Several sensors placed in key positions on the refrigerant circuit electronically detect the

operational state of the system.

A Micro Controller Unit receives the inputs from the sensors, elaborates them using advanced algorithms

and optimizes the refrigerant flow and the functioning of core components: compressor, fan

motors and the pulse modulation valve.

GMC control continuously analyzes the water, indoor ambient conditions and the

customer requests and sends commands to the CDU control.

GMC control also manages all the system input/output, user

interface, and compressor operation management.

The CDU control takes care of the system reliability and

satisfies the requests coming from GMC control driving fan motor, PMV and compressor.The CDU control continuously

sends back signals to the GMC control.

A number of parameters determine how and under which conditions the HP will ask the support of the auxiliary heater (electric, gas boiler, a.s.o.) and activates the additional water pump.

Whatever is the outdoor temperature the HP will be the only one working should a DHW request come.

Controls – Logic


AIR HP


Controls – Internal safetiesSeveral routines are built-in in the PCBs so to grant at any time the best working conditions of all the components and to protect both the machine and the installation while maximising the comfort for the user.

-MAIN and ADDITIONAL pump anti-seizing function- Room anti-freeze function- Compressor Short Cycling Protection (Timeguard): to protect the compressor form

short cycles and too often on/off. The maximum allowed number of cycles every hour is SIX

- Minimum Compressor Run Time: to protect the compressor form short cycles and too often on/off. The compressor is forced to work for a minimum of three minutes even if in the meantime the heat request has stopped

- Water anti-freeze protection: should the water in/out the plate heat exchanger go below a certain value, the compressor is stopped

- Water over-temperature protection: should the water in/out the plate heat exchanger go over a certain value, the compressor is stopped

- Water anti-frost protection due to outdoor temperature. The trace heater, the water pump, the machine are turned ON in sequence according to the probes readings.

- Discharge temp release control: compressor protection due to over-temperature of the refrigerant temperature reading.

- Current release control: compressor protection due to over-current absorbed


AIR HP


Controls – Comfort functions.

- In all the machines the fans speeds are modulated so to reduce the noise: 4;6;8 kW machines – modulation along a continuous range of values; 12;15 kW units: the two fans are modulated with different speeds

- compressor warm up procedure: it warms up the compressor to avoid a slackness of refrigerant inside the component. The procedure is monitored and stopped reading the current absorption

- defrost control on the fanned heat exchanger, so to grant constantly the efficiency of such exchanger.

WEEE (2003/108/EC)Units must be collected separately after its use is completed, and cannot be disposed as unsorted municipal waste. Objectives:

• to tackle the fast increasing waste stream of electrical and electronic equipment,

• to increase recycling of electric & electronic equipment (“EEE”),• to limit the total quantity of waste EEE (“WEEE”) going to final disposal.

The crossed out wheeled bin symbol that is affixed to the product means thatthis product falls under the Directive. The user is responsible for returningthe product to the appropriate collection facility, as specified by your municipality or the distributor.In case of installation of a new product, it may be possible to have the distributor pick up old WEEE directly.

In the following slides there are a few installation schemes with the purpose to give a flavour of the different possible installations of the machine inside a (new or renovated)

system.

It is important to notice that there is the need for the installer to complete the system with a handful of components, among which the most important is probably the WATER

FILTER.It is in fact extremely important to avoid that any dirt, metal shavings, sludge, dirt end

up in the plate heat exchanger, to avoid its seizing.
