What is ATW heat pump?1

1-1. Compare with conventional fossil fuel boiler

• Heat pumps produce water at 30°C – 60°C

• Ideal for underﬂ oor heating

• Average underﬂ oor heating circuit 35°C

• Fossil fuel boilers heat water to 80°C

• Flow temp in rads design temp approx 70°C

• Heat pumps can still be used with radiators

• Larger surface area to emit heat from lower temp water

1-2. Points to notice

1-2-1. Design (Radiator sizing)

• Careful consideration must be given to appropriate application of this technology to maximise its beneﬁ ts – it will not suit all properties, especially many retroﬁ ts

• Heat emitters may need to be larger

• Lower ﬂ ow temperatures maximise COP

• Various regulations apply to the design and installation of such systems

• Because the ﬂ ow temp. of heat pump is low compare to fossile fuel boiler, the temperature difference between the primary (ﬂ ow water) and secondary (room air) becomes little, it makes the heat emission little. To emit the same amount of heat energy, it is needed to select the radiator that has a larger surface area. Be especially careful of the surface area when you design the radiator.

1-2-2. Defrost

Note: Occasionally, vapor that is made by the defrost operation may seem as if smoke come up from the outdoor unit.

1-2-3. Water Pressure loss (for packaged type outdoor unit)

• Water pressure lose of the heat exchangers are as follows.

Be aware of the inﬂ uence when you design total pipng system.

Notiﬁ cation to design/select HEX (Refrigerant - Water)

• Speciﬁ cations of AHU and compatibility with regulations must be conﬁ rmed by your company.

• Selection of an apporopriate AHU (with appropriate speciﬁ cations to match those of units connected to the AHU such as conﬁ guration, dimension, life-span, vibration, noise level, or features) must be made by your company.

• Mitsubishi Electric shall not be liable for any damage to the entire system or the AHU main body caused by connected AHU with wrong speciﬁ cation or wrong usage of AHU.

• Mitsubishi Electric shall not be liable for any damage to the outdoor units caused by AHU damage.

( AHU : hydro box or refrigerant - water HEX )

Heat exchanger

(1) Withstanding pressure

Designed pressure of outdoor unit is 4.15 MPa. Following must be satisﬁ ed for burst pressure of connecting application. Burst pressure : More than 12.45 MPa (3 times more than designed pressure)

(2) Performance

Secure the heat exchanger capacity which meets the following conditions. If the conditions are not met, it may result in malfunction caused by the protection operation or the outdoor unit may be turned off due to the operation of protection system.

1. Evaporate temperature is more than 4: in max. frequency operation under *1 the cooling rated conditions.

2. In case of hot water supply, condense temperature is less than 58: in max. frequency operation with the outside temperature 7:D.B./6:W.B. *1. Outdoor: 35:D.B./24:W.B.

(3) Heat exchanger internal capacity

Heat exchanger internal capacity must be within the capacity range shown below. If the heat exchanger below the minimum capacity is connected, it may result in the back ﬂ ow of liquid or the failure of the compressor. If the heat exchanger above the maximum capacity is connected, it may result in the deﬁ ciency in performance due to lack of refrigerant or overheating of the compressor. Minimum capacity : 10 х Model capacity [J] / Maximum capacity : 30 х Model capacity [J] e.g. When connecting to PUHZ-HRP100 VHA2

Minimum capacity : 10 х 100 =1000

Maximum capacity : 30 х 100 =3000 Model capacity 60(2.5HP) 71(3HP) 100(4HP) 125(5HP) 140(6HP) Maximum capacity [J] 1800 2130 3000 3750 4200 Minimum capacity [J] 600 710 1000 1250 1400

Warranty for SPILIT solution

(4) Contamination maintenance

1. Wash the inside of heat exchanger to keep it clean. Be sure to rince not to leave ﬂ ux. Do not use chlorine detergent for wash.

2. Be sure that the amount of contamination per unit cubic content of heat transfer pipe is less than the following amount. Example) In case of [ 9.52mm Residual water : 0.6M/C, Residual oil : 0.5M/C, Solid foreign object : 1.8M/

Note:

• Install the hydraulic ﬁ lter at the water intake.

• Use the inlet water of higher than 5 ˚C and lower than 55 ˚C.

• The water in a system should be clean and with pH value of 6.5-8.0.

• The followings are the maximum values; Calcium : 100mg/L Chlorine : 100mg/L Iron/manganese : 0.5mg/L

• Refrigerant pipe diameter from outdoor unit to refrigerant-water HEX (Only for SPLIT type) Use the pipe with same diameter size as the refrigerant pipe connection diameter of outdoor unit.(Refer to outdoor unit installation manual.)

• Make sure to perform the frozen prevention measure for water pipe system.(Water piping insulation, back-up pump system, using of a certain % ethylene glycol instead of normal water)

[Reference]

TB142 has for “Forced Comp. OFF” function as the EXTERNAL INPUT(Contact signal). To input the abnormal signal of water pump or the abnormal lowering of water ﬂ ow amount with non-voltage contact signal makes the outdoor unit stop forcibly. For details, refer to each part of I/F or FTC on this manual.

• The water velocity in pipes should be kept within certain limits of material to avoid erosion,corrosion and excessive noise generation. Be aware, and take care of , that local velocities in small pipes, bends and similar obstructions can exceed the values of previous page.

e.g.) Copper : 1.5m/s

Warning

• Use clean enough water which meets water quality standards. The deterioration of water quality may result in the system breakdown or the water leakage.

• Never use anything other than water as a medium. It may cause a ﬁ re or an explosion.

• Do not use heated or cooled water that is produced by the air to water heat pump directly for drinking or cooking. There is a risk to damage your health. There is also a risk that installing the water heat exchanger may corrode if the necessary water quality for air to water heat pump system cannot be maintained. If you wish to use the heated or cooled water from the heated pump for these purposes, take measure such as to the second heat exchanger within the water piping system.

2. Interface controller and outdoor connecting wires have poIarities, make sure to match

terminal numbers(S1, S2, S3) for correct wirings.

3. Since the outdoor side electric wiring may change, be sure to check the outdoor unit

electric wiring diagram for servicing.

4. This diagram shows the wiring of Interface controller and outdoor connecting wires.(specification of 230V),

adopting superimposed system of power and signal.

Notes on system controller side in I/F connection system (1)Please do not transmit “STEP 0” during defrost operation.

Defrost operation might be interrupted, and frost remain. (Please demand the planned capacity step even when the system controller receives defrost signal from the heat pump (outdoor unit)).

(2)Please do not transmit “STEP 0” when the outdoor unit(H/P) is abnormal.

Abnormal detection data is reset, and an Abnormal point cannot be conﬁ rmed.

1. System outline

With PAC-IF011B-E, local units can be connected with the outdoor units manufactured by MITSUBISHI ELECTRIC. The commands, such as Remote switch, Varistor, 4-20mA/1-5V/0-10V and etc., allow the inverter outdoor unit to operate, to stop and to switch capacity. By outputting the operation state, the interface can be connected with the local unit.Also, the interface can be connected with wired remote controller for maintenance so that the maintenance information is obtained. Only the outdoor units with self-controlled S/W are connectable.

2. System structure

System structure(1)

Outdoor unit capacity switch

Remote switch

Capacity switch of outdoor unit according to the remote switch

When auto stop being set, the difference between room temperature and set temperature of interface, and the pipe temperature switch the capacity of outdoor unit automatically.

Wired remote controller (Auto step mode only)

The difference between room temperature and set temperature of wired remote controller, and the pipe temperature switch the capacity of outdoor unit automatically.

As with the remote controller for air conditioner, the interface performs ON/OFF operation, and changes operation mode (cooling, heating ,fan) and set temperature.

Adjustable resistor(0-10k)
