Outlet temperature of hot water to 80 °C even with outdoor temperature -20 °C.
It is ideal for boiler replacement in existing facilities,
operated heaters, high temperature (AKAN, steel panels, aluminum). |
| |
|
Smart cycle sequential Operation compressors (smart cascade), which combines the best Capasity 1 cycle (R410A-H2O) for Low Temperatures and combinatorial Operation 2 cycles (R410A-R134a and R134a-H2O) for High Temperatures of water. So there is a greater degree capasity COP from the conventional systems. |
| |
|
| |
The high temperature of 80 °C water and the high degree of COP, is feasible even in colder outdoors Temperatures.
The Yutaki S80, can maintain constant heating capacity even at low ambient outdoors Temperatures (-20 °C), without the need to use other existing means of water heating and domestic hot water (DHW) such as electrical heater or boiler etc.
Multiple Operation:
space heating, heating water for use in residential installations, a combination of solar energy, combining with existing boiler installation or electrical resistances. Moreover some combination of Yutaki S80 systems with different heating: radiator / fan coil, Underfloor heating or combination thereof. |

floor support units with multiple connectivity options:
Autonomous Indoor unit with or without integrated hot water tank
use (ZNX) house Hitachi, and autonomous Indoor unit while
connection and floor support, tank DHW other firms (after market).
Small Dimensions and footprint (Width 595 mm), suitable for indoor
auxiliary residential areas (<600 mm).
Easy maintenance and repair: major functional components
the unit is accessible from the front side. For instance,
the electrical box unit, easily removable from the front side, just disconnecting plug suitably.
Easy connection piping (and potential cross connection through flexible member of the firm Hitachi) akomakai in installations with limited access.
Easy wiring and powering the unit: great design with electrical
connections and schematic diagrams.
Fingertip control and programming unit via a wired controller with integrated LCD display and advanced menus easy handling
(plug & play). |

System high capasity
The combination of inverter scroll compressor used by heat pumps Yutaki S80, smart successive cooling cycle (smart cascade), the use of three (3) heat exchangers and high capasity of water pumps (circulators) Low power consumption, leading to a system extremely high energy efficiency has the largest COP degree capasity market.
|
| |
High heating capasity
The series Yutaki S80, provides the highest Heating capasity market in heating systems with high Temperatures water outlet.
It is available in a wide range of temperatures outdoorerikon suitable for even the coldest conditions (-20 °C). |
| |
|
| |
|
| |
|
The outlet temperature of the water, can achieve 80 °C even in outdoor temperature -20 °C.
The Yutaki S80, can replace the boiler in existing facilities, is the ideal solution for old heating systems that work with old-style radiator with low insulation and large losses.
|
|
|
|
The Hitachi, with rows Yutaki S80 and Yutaki S, covering the whole range of needs that exist in the heating market, either for hot water production with high Temperatures, either for hot water production with low Temperatures.
Moreover the series Yutaki S, covers and cooling requirements and cooling (underfloor cooling system / water terminal units FCU). |

| Simple sequential refrigeration cycle (Cascade) |
|
|
The market needs so far, in installations where the refrigeration cycle is required to work at very low Temperatures Exhaust established expertise principle of simple sequential cooling cycle. In these types of installations, a simple Refrigerant, is not able to evaporate at low Temperatures with positive pressure (greater from 1 atm), or to condense at high Temperatures and pressures after being influenced by the performance.
The solution in these cases, a facility was composed from two refrigerant cycles (high and low temperature), thermally bonded via an intermediate heat exchanger. This system is known as a simple sequential refrigeration cycle. |
| |
| The cycle low temperature, using as Phreon Refrigerant R-410A, which allows the evaporation at low temperature and a positive pressure. Condensation of R-410A is in the intermediate heat exchanger at a relatively low pressure, however metaPherontas heat in the evaporator circuit of the cycle high heating, which uses as diaPhoretiko Phreon Refrigerant R-134a. The concentration of the low temperature refrigerant R-410A, causing the evaporation of the high temperature R-134a. |
| The simple sequential cycle, working continuously and simultaneously using the two circuits, which provides an optimal functional outcome but with great power Consumption. |

Innovation HITACHI
Smart sequential refrigeration cycle (Smart Cascade) |
|
|
The Hitachi innovating, presents the series Yutaki S80 technologically advanced smart successive cycle (smart cascade), satisfying the best possible result in heating & hot water needs, combined with maximum savings Energy.
This innovation allows the exploitation of maximum capasity of the system, depending on the outlet temperature of the water or require any appliances. |
| |
| In this way, when the facility will require a low temperature water outlet, only one cycle will run (R410-H2O), and when required a high temperature will be activated and the two circles (R410A, R134a and R134a-H2O). |
| The control of these two circuits is done through remotely controlled valves SV1 and SV2. When the unit is to be operated with just one cycle, the valve SV1 = ON and SV2 = OFF. When installation needs require Operation and 2 circuits then the condition of the valves is SV1 = OFF and SV2 = ON. |
| |
|
|
Moreover, this innovative sequential cycle Yutaki S80, leads to several best grade capasity COP, as it exploits the best conditions and Operation capasity every time. |
