DEAKON R32 Full Inverter Air to Water Heat Pump is Ready!

R32, More Eco-friendly 

R32 HP is a low GWP refrigerant of 675, it can reduce 75% of global warming gas 

emissions, providing a lower carbon release than most other HFCs.

General

Deakon A2 Premium solar + air source heat pump extracts heat from the air 

and sun, even when the temperature is as low as -35C and converts it to 

useable heat to provide heating and hot water. (Please refer to our working 

principle diagram of heat pump.) 

Deakon A2 premium solar + air source heat pumps are inverter controlled 

which means they can operate at different outputs to suit the ambient 

weather conditions and the heating needs of the building. 

Suitable for projects of all sizes 

We provide heat pumps up to 22kW. If necessary, multiple units can be 

integrated into the system; No matter the size of the project you think of, we 

can design a suitable system.

Working temp range extended down to -35℃ 

Dual evaporator design - Compared to traditional single evaporator models, solar panel plus air source heat exchanger design further increases the ability to absorb heat from nature such as sunlight, rain and air. Inverter models can operate at -20 or -25 degrees outdoor environments, the Deakon A1 Premium dual source inverter models can operate at -35 degrees outdoor temperature and provide higher heat capacity and COP than only inverter model.

The average defrosting time was reduced by 50%

Thanks to the dual evaporator design, Defrosting time is reduced by 50% compared to traditional air source heat pumps. Deacon A1 Premium models hardly needs defrosting during the day, even when the temperature is below zero degrees

Hybrid inverter EVI technology 

The EVI compressor system can work at low ambient temperature but its operation speed is fixed, hence the efficiency is not so good. 

The Inverter compressor system has very high COP because its operation speed is adjustable according to the ambient and water outlet/inlet temperature variation, but the output heating capacity is not as good as EVI compressor at low temperature. 

The Hybrid inverter EVI compressor combined both advantages of inverter and EVI compressor which can work at very low ambient temperature meanwhile produce high capacity and COP

Low noise 

Deakon adopts large diameter sawtooth axial fan, which has lower vibration than conventional axial fan. In addition, the system adopts a flexible long U-shaped copper pipe with damper, and the inner surface of the cabinet is completely covered with rubber and plastic soundproof cotton. These methods considerably decrease vibration and noise.

Mobil APP remote control 

1.Hybrid Inverter&EVI compressor

High efficiency— inverter driven, compressor speed is adjusted according to the temperature and load changing. 

Suitable for ultra-low ambient temperature (-25℃) heat pump heating field Adopts Panasonic special piston self-sealing technology to replenish air, no moving parts, longterm high reliability 

The small liquid storage device is added on the air replenishment side, so the pressure is 

gentle during the replenishment and the noise and vibration are small. 

2.Reservoir

Collect the liquid refrigerant from the condenser to ensure the heat transfer area of the 

condenser.

3.Dc motor and silent fan 

Step-less Dc fans can maximize performance with lower power consumption and have the advantage of low noise. 

4.Electrical expansion valve 

The Saglnomlya electronic expansion valve is a self-locking type and is applicable to a wide range of refrigerants. It can flow forward or reverse, permanent magnet stepper motor drive; 

DC12V rectangular wave control voltage 

5.Stainless plate heat exchanger

Plate heat exchangers have the following advantages: high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, long service life; with the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, which covers an area of one third of the tube heat exchanger. 

6.Intelligent inverter controller 

3 Channel &3 phase interleaving PFC technology 

The core algorithm of compressor driver180° sine wave vector control technology 

Self-adapting vibration suppression technology 

High frequency flux-weakening technology 

Magnetic saturation control technology 

EVI control solution for-30℃ application environment 

Solar energy helps to increase capacity and reduce power consumption 

The solar panel uses metal materials, it is refrigerant circulation type not solar power type, it is used as the first evaporator, and there is a second evaporator inside the heat pump. The first evaporator absorbs heat directly from the sunlight then transfers the heat energy to the second heat exchanger. Its temperature is higher than that of the second evaporator, which absorbs heat from the air. That means that the two energy sources are combined into one and compressed by the compressor to generate high-temperature energy, which is then transferred through the condenser to heat water ( storage tank and room heating system). This is very efficient when there is sunshine during the day, even though the air ambient temperature is very low.

1. Electrical 3 way valve 1

2. Electrical 3 way valve 2

3. A Circulation pump A

4. A Circulation pump B

AUTO TANK HEATING +ROOM COOLING MODE :

The heat pump first runs in heating mode and produces hot water into buffer tank via three-way valve 1, then separates hot water into DHW cylinder via three-way valve 2 for tank heating. When its set temperature is reached, it automatically exchanges three-way valve 1 and the heat pump in cooling mode and produces cold water into fan coils for room cooling.

AUTO TANK+ROOM HEATING MODE:

The heat pump runs in heating mode and produces hot water into buffer tank via three-way valve 1, then separates hot water into DHW cylinder for tank heating. When its set temp is reached, then automatically exchanges three-way valve 2 and separates hot water into room heating system (radiator/floor pipe)
