1.1.2 Introduction

HITACHI proudly announces the newest complete range of air-to-water heat pumps in its award-winning YUTAKI range.

YUTAKI units produce heating and domestic hot water like any oil or gas boiler, but transforming renewable energy from the outside air into heat. Air to water heat pumps extract the free energy present in the air, which is enough to heat a home up to a comfortable temperature, even on the coldest winter day. Every kW of electricity used to power the heat pump can yield up to more than 5 kW of energy for heating; this provides savings of up to 80% on heating expenses compared to a traditional fossil fuel boiler.

The new YUTAKI series, based on state-of-the-art technology, does not only achieve an outstanding performance in space heating but also provides domestic hot water with high efciency. Additionally, cooling operation for summer can also be provided installing

the dedicated “Cooling kit” accessory of HITACHI.

The system is simple to control; its new user controller (PC-ARFHE) improves the acclaimed and successful design used with the existing LCD controller and provides a great deal of new functions like: wizard start-up conguration, auto cool/heat, improved timer,

etc.

1.1.2.1 Overview of YUTAKI system

The wide range of YUTAKI products is basically divided in two types of system:

• Split system

• Monobloc system

Split system - YUTAKI S, YUTAKI S COMBI, YUTAKI S80



It consists of one outdoor unit and one indoor unit. The outdoor unit extracts the heat present in the air, increases its refrigerant temperature and transmits it to the water circuit using the plate heat exchanger of the indoor unit where the heat is taken to radiators (fan-coils), underoor heating components or both (2nd temperature area).

Three types of indoor unit can be used in heating split systems:

YUTAKI S

The indoor unit of YUTAKI S is designed for space heating, in wall-mounted installation. It is convenient for new installations with low capacity requirements (Well isolated installations, high efciency radiators...).

YUTAKI S COMBI

The indoor unit of YUTAKI S COMBI is conceived as a oor standing unit. It is prepared for heating operation as well as for domestic hot water production. For this purpose, it has a built-in domestic hot water tank available in two sizes (200 or 260 L). In line with YUTAKI S units, it meets the needs of installations with low capacity requirements.

Furthermore, special YUTAKI S COMBI models have been designed with a specic solar tank for the use of solar panels.

Also, new models of YUTAKI S Combi have been specially designed for the UK market that meet the requirements referred in the UK Building Regulations.

GENERAL INFORMATION

YUTAKI S80

The YUTAKI S80 is a standalone indoor unit that generates hot water up to 80ºC; the hottest water temperature in the domestic heating market using renewable energy.

The extra innovation in the YUTAKI S80 lies in that it has two compressors, working in a smart cascade system, with two refrigerant cycles (R-410A and R-134a). To maximize seasonal efciency, the second refrigerant cycle is only operated as a booster, when very high water temperature is required - the rest of the time, only one cycle is used.

The YUTAKI S80 is ideal for existing properties, in particular older installations where high water supply temperatures may be required to keep the house warm – as well as for new buildings. It is designed for the replacement of boilers, offering heating and sanitary hot water all year round, without boiler back-up.

Two different models have been designed for different purposes: one model for space heating only and the other one for space heating as well as for DHW operation. For DHW operation (optional), HITACHI offers two specic YUTAKI S80 DHW tanks (DHWS200S-2.7H2E and DHWS260S-2.7H2E) which may be placed on top of the indoor unit or besides it, as an integrated unit to provide high-temperature domestic hot water enjoying the benets of the high efciency of the heat pump.

Monobloc system - YUTAKI M



YUTAKI M is a monobloc air to water heat pump system, composed by only an special outdoor unit, which carries out the function of an air-to-water heat pump. This results in an excellent solution when installation space available is limited.

YUTAKI M is designed to be installed outdoors, in any kind of dwelling (house, apartment, villa,…), whether in a new construction or in an existing building. Installation work is greatly simplied thanks to the lack of refrigerant piping connections.

1.1.2.2 Summary of operations

Space heating

YUTAKI units are factory-supplied ready for space heating operation. Different heating installation congurations can be selected providing a comfortable atmosphere all year long even in the coldest climates:

• Mono-valent system

The air to water heat pump is sized to provide 100% of the heating requirements on the coldest day the year.

• Mono-energy system

This is the most popular conguration. The air to water heat pump is sized to provide 80% of the heating requirements on the coldest days of the year. An auxiliary electric heater is used to provide the additional heating required on cold days. This option usually results in an ideal balance between installation costs and future energy consumption, as proven by its popularity in colder climates than ours, such as Sweden and Norway.

• Alternating Bi-valent system

For installations with an existing heating system by boiler, and when is needed to heat the supplied water temperature to the circuit up to high temperatures (80ºC), the boiler can be congured to alternate with the air to water heat pump.

Selecting the different conguration types it is possible to adapt the system to all customer requirements, providing a wide application range from the simplest conguration to complete conguration: Radiator, heating oor or both (2nd temperature area).

Domestic hot water production

YUTAKI models also give the option of domestic hot water production, allowing the user to benet from the heat pump’s high efciency and achieve domestic hot water.

This is made possible by a domestic hot water tank. In case of YUTAKI S COMBI, the domestic hot water tank is built in the indoor unit. In YUTAKI S80, a specic DHW tank is designed for combination with the indoor unit. For YUTAKI S and YUTAKI M, the HITACHI accessory “DHWT-(200/300)S-3.0H2E” can be used for the production of DHW.

An electric heater is incorporated inside the tank in order to allow an immediate heating of the domestic hot water in accordance with the user’s needs.

PMML0335A rev.1 - 04/2016

GENERAL INFORMATION

Space cooling

YUTAKI units can also be operated in cooling operation The dedicated “Cooling kit” accessory has been designed for this purpose. Combining the heating only models with these cooling kits, the reversible models become available. In this case, combination with fan-coils, refreshing oor or both (2nd temperature area) can be applied.

Combination with solar panels

YUTAKI system can be combined with solar panels. The solar combination enables to heat up the DHW by means of the sun. The solar combination is designed to transfer the heat from the solar panels (sun radiation) to the heat exchanger of DHW tank.

In case of YUTAKI S COMBI, a specic model with integrated tank for solar combination has been designed, as explained before.

Swimming pool water heating operation

For summer session period, YUTAKI system can be used to heat the water temperature of swimming pools up to a value between 24 and 33ºC.

3.3.1 Considerations

• The sound data is based on the following conditions:

- Outdoor ambient temperature (DB/WB): 7/6ºC.

- Water inlet/outlet temperature: 47/55ºC (mark: *1); 30/35ºC (mark: *2).

- Distance of the unit from the measuring point: At 1 meter from the unit’s front surface; 1,5 meter from oor level.

- The sound pressure level is measured in an anechoic chamber, so reected sound should be taken into consideration when

installing the unit.

- The sound power level is measured in a reverberant room, in accordance with the standard EN12102. Used environment

conditions are the same that specied in EN14511 for performance test.

• The nominal water ow rate is calculated under the following conditions:

- Outdoor ambient temperature (DB/WB): 7/6ºC.

- Water inlet/outlet temperature: 47/55ºC (mark: *1); 30/35ºC (mark: *2).

• Regarding data market with (mark: *3), it corresponds to the height of the unit with the minimum mounting foot height. This value

can be adjusted up to +30 mm.

• For specic details about data corresponding to the working range, please refer to the chapter “4 WORKING RANGE”.

6.1.2 Precautions in the event of gas refrigerant leaks

The installers and those responsible for drafting the specications are obliged to comply with local safety codes and regulations in

the case of refrigerant leakage.

! CAUTION

• Check for refrigerant leakage in detail. If a large refrigerant leakage occurred, it would cause difculty with breathing or harmful gases would occur if a re were in the room.

• If the are nut is tightened too hard, it may crack over time and cause refrigerant leakage.

Maximum permitted concentration of HFCs

The refrigerant R410A (charged in the outdoor unit) and the refrigerant R134a (in case of YUTAKI S80 indoor unit) are incombustible and non-toxic gases. However, if leakage occurs and gas lls a room, it may cause suffocation.

The maximum permissible concentration of HFC gas according to EN378-1 is:

Refrigerant Maximum permissible concentration (kg/m3)

R410A 0.44 R134a 0.25

The minimum volume of a closed room where the system is installed to avoid suffocation in case of leakage is:

8 HP 11.4

10 HP 12.1

The formula used for the calculation of the maximum allowed refrigerant concentration in cases of refrigerant leakage is the following:

R — = C

R: Total quantity of refrigerant charged (kg) V: Room volume (m³) C: Refrigerant concentration

If the room volume is below the minimum value some effective measure must be taken into account after installing to prevent

suffocation is case of leakage.

Countermeasure in the event of possible refrigerant leakage



The room must have the following features to prevent suffocation in case a refrigerant leakage occurs:

1 Provide a shutterless opening which will allow fresh air to circulate into the room. 2 Provide a doorless opening of 0.15% or more size to the oor area. 3 There must be a ventilator fan connected to a gas leak detector, with a ventilator capacity of 0.4 m³/min or higher per Japanese

refrigeration ton (= compressor displacement volume / (5.7 m³/h (R410A) or 14.4 m³/h (R134a)) of the air conditioning system

using the refrigerant.

? NOTE

Always take the maximum value between the R410A and R134a.

4 Pay special attention to the place, such as a basement, etc., where the refrigerant can stay, since refrigerant is heavier than air.
