1 Air-to-Water HP Split System 1.1 System Schematic Figure 1-1.1: System schematic Hydronic Box Fan Coil Units Under-floor Heating Loops M-Thermal Split outdoor unit Distributor By-pass Valve 3Way Valve Collector Cold Water Inlet DHWTank It is an integrated air-to-water heat pump split system which is one-stop solution for space heating, space cooling and domestic hot water.
1.2 System Configurations It can be configured to run with the electric heater either enabled or disabled and can also be used in conjunction with an auxiliary heat source such as a boiler. The chosen configuration affects the size of heat pump that is required. Three typical configurations are described below. Refer to Figure 1-1.2. Configuration 1: Heat pump only ▪ The heat pump covers the required capacity and no extra heating capacity is necessary.

4 System Design and Unit Selection 4.
4.2 Heat Pump Leaving Water Temperature (LWT) Selection The recommended design LTW ranges for different types of heat emitter are: ▪ For floor heating: 30 to 35⁰ C ▪ For fan coil units: 30 to 45⁰ C ▪ For low temperature radiators: 40 to 50⁰ C 4.
5 Typical Applications 5.1 Space Heating Only The room thermostat is used as a switch. When there is a heating request from the room thermostat, the unit operates to achieve the target water temperature set on the user interface. When the room temperature reaches the thermostat’s set temperature, the unit stops. Figure 1-5.
5.2 Space Heating and Domestic Hot Water The room thermostats are not connected to the hydronic box but to a motorized valve. Each room’s temperature is regulated by the motorized valve on its water circuit. Domestic hot water is supplied from the domestic hot water tank connected to the hydronic box. A bypass valve is required. Figure 1-5.
5.3 Space Heating, Space Cooling and Domestic Hot Water Floor heating loops and fan coil units are used for space heating and fan coil units are used for space cooling. Domestic hot water is supplied from the domestic hot water tank connected to the hydronic box. The unit switches to heating or cooling mode according to the temperature detected by the room thermostat. In space cooling mode, the 2-way valve is closed to prevent cold water entering the floor heating loops. Figure 1-5.
5.4 Space Heating and Domestic Hot Water (Bivalent) 5.4.1 Auxiliary heat source provides space heating only Figure 1-5.
5.4.2 Auxiliary heat source provides space heating and domestic hot water Figure 1-5.
5.4.3 Auxiliary heat source provides additional heating If the unit’s outlet temperature is too low, the auxiliary heat source provides additional heating to raise the water temperature to the set temperature. An additional 3-way valve is required. When the unit’s outlet temperature is too low, the 3-way valve is open and the water flows through the auxiliary heat source. When the unit’s outlet temperature is high enough, the 3-way valve is closed. Figure 1-5.
5.5 Space Heating Through Floor Heating Loops and Radiators The floor heating loops and radiators require different operating water temperatures. To achieve these two set points, a mixing station is required. Room thermostats for each zone are optional.With the help of hydronic adapter board(optional), maximum 8 thermostats for 8 rooms are available to control heat pump, which greatly improves the operation convenience. Figure 1-5.7: Space heating through floor heating loops and radiators RAD. 1 RAD.
5.6 Space Heating, Space Cooling and Domestic Hot Water Compatible with Solar Water Heater Floor heating loops and fan coil units are used for space heating and fan coil units are used for space cooling. Domestic hot water is supplied from the domestic hot water tank connected to both the hydronic box and solar water heater. Solar water pump is controlled by Tsolar temperature sensor. Balance tank temperature sensor is used to control on/off of heat pump.

1 Preface to Part 3 1.1 Notes for Installers Boxes The information contained in this Engineering Data Book may primarily be of use during the system design stage of a Air‐to‐Water Heat Pump Split project. Additional important information which may primarily be of use during field installation has been placed in boxes, such as the example below, titled “Notes for installers”.
2 Installation 2.1 Acceptance and Unpacking Notes for installers ▪ When units are delivered check whether any damage occurred during shipment. If there is damage to the surface or outside of a unit, submit a written report to the shipping company. ▪ Check that the model, specifications and quantity of the units delivered are as ordered. ▪ Check that all accessories ordered have been included. Retain the Owner’s Manual for future reference. 2.
2.3 Outdoor unit 2.3.1 Placement Considerations Placement of the outdoor unit should take account of the following considerations: ▪ Outdoor units should not be exposed to direct radiation from a high-temperature heat source. ▪ Outdoor units should not be installed in positions where dust or dirt may affect heat exchangers. ▪ Outdoor units should not be installed in locations where exposure to oil or to corrosive or harmful gases, such as acidic or alkaline gases, may occur.
▪ Fix the unit securely to foundation by means of the Φ10 expansion bolt. It is best to screw in the foundation bolts until their length is 20 mm from the foundation surface. Figure 3-2.3: Outdoor unit fixing Φ10 Expansion bolt Rubber shocking proof mat Solid ground or roofing Concrete basement h≥100mm (unit: mm) 2.3.
Figure 3-2.5: 8-16kW models drainage hole Drain hole This drain hole is covered by rubber plug. If the small drain hole can not meet the drainage requirements, the big drain hole can be used at the same time. 2.3.7 Transportation support For 12/14/16kW model, there is a transportation support which is used to protect tubes from breaking during transportation and this support should be taken off before turning on the heat pump. Figure 3-2.6: 12-16kW models 2.3.

2.4 Hydronic box 2.4.1 Placement Considerations ▪ Hydronic box should be installed in positions that are as close as possible to the heat emitters. ▪ Hydronic box should be installed in positions that are sufficiently close to the desired position of the wired controller that the controller’s wiring length limitation will not be exceeded.
2.4.3 Service space requirement The service space requirements refer to Figure 3-2.15. Figure 3-2.15: Service space requirement (unit:mm) 2.4.4 Drainage The drainage connections of hydronic box refer to Figure 3-2.16. Figure 3-2.
3 Refrigerant Pipework 3.1 Permitted Piping Length and Level Difference The piping length and level difference limitations that apply are summarized in Table 3-3.1. Before installation, it is necessary to check if the piping length and height difference are meeting the requirements. Table 3-3.1: Permitted Piping Length and Level Difference Models 4-16kW Max. piping length 30m Max. difference in height 20m Figure 3-3.1: Connect method Outdoor Unit Indoor Unit max.
3.3 Procedure and Principles 3.3.1 Installation procedure Notes for installers Installation of the refrigerant piping system should proceed in the following order: Pipe insulation Pipe brazing and installation Pipe flushing Gas tightness test Joint insulation Vacuum drying Note: Pipe flushing should be performed once the brazed connections have been completed with the exception of the final connections to the indoor units.
3.4 Storing Copper Piping 3.4.1 Pipe delivery, storage and sealing Notes for installers ▪ Ensure that piping does not get bent or deformed during delivery or whilst stored. ▪ On construction sites store piping in a designated location. ▪ To prevent dust or moisture entering, piping should be kept sealed whilst in storage and until it is about to be connected. If piping is to be used soon, seal the openings with plugs or adhesive tape.
3.5.3 Expanding copper piping ends Notes for installers ▪ Ends of copper piping can be expanded so that another length of piping can be inserted and the joint brazed. ▪ Insert the expanding head of the pipe expander into the pipe. After completing pipe expansion, rotate the copper pipe a few degrees to rectify the straight line mark left by the expanding head. Caution ▪ Ensure that the expanded section of piping is smooth and even. Remove any burrs that remain after cutting. Figure 3-3.
3.5.5 Bending piping Bending copper piping reduces the number of brazed joints required and can improve quality and save material. Notes for installers ▪ Piping bending methods ▪ Hand bending is suitable for thin copper piping (Ф6. 35mm - Ф12. 7mm). ▪ Mechanical bending (using a bending spring, manual bending machine or powered bending machine) is suitable for a wide range of diameters (Ф6. 35mm - Ф54.0mm). Figure 3-3.
3.7 Brazing Care must be taken to prevent oxide forming on the inside of copper piping during brazing. The presence of oxide in a refrigerant system adversely affects the operation of valves and compressors, potentially leading to low efficiency or even compressor failure. To prevent oxidation, during brazing nitrogen should be flowed through the refrigerant piping.
… box continued from previous page Piping orientation during brazing Brazing should be conducted downwards or horizontally to avoid filler leakage. Figure 3-3.7: Piping orientation during brazing Braizing Braizing Braizing Piping overlap during brazing Table 3-3.5 specifies the minimum permissible piping overlap and the range of permissible gap sizes for brazed joints on piping of different diameters. Refer also to Figure 3-3.8. Figure 3-3.
3.8 Pipe Flushing 3.8.1 Purpose To remove dust, other particles and moisture, which could cause compressor malfunction if not flushed out before the system is run, the refrigerant piping should be flushed using nitrogen. As described in Part 3, 3.3.1 “Installation procedure”, pipe flushing should be performed once the piping connections have been completed with the exception of the final connections to the hydronic box.
3.9 Gastightness Test 3.9.1 Purpose To prevent faults caused by refrigerant leakage, a gastightness test should be performed before system commissioning. 3.9.2 Procedure Notes for installers Warning Only dry nitrogen should be used for gastightness testing. Oxygen, air, flammable gases and toxic gases must not be used for gastightness testing. Use of such gases may result in fire or explosion.
3.9.3 Leak detection Notes for installers The general methods for identifying the source of a leak are as follows: 1. Audio detection: relatively large leaks are audible. 2. Touch detection: place your hand at joints to feel for escaping gas. 3. Soapy water detection: small leaks can be detected by the formation of bubbles when soapy water is applied to a joint. Figure 3-3.
3.10.2 Procedure Notes for installers During vacuum drying, a vacuum pump is used to lower the pressure in the piping to the extent that any moisture present evaporates. At 5mmHg (755mmHg below typical atmospheric pressure) the boiling point of water is 0°C. Therefore a vacuum pump capable of maintaining a pressure of -755mmHg or lower should be used. Using a vacuum pump with a discharge in excess of 4L/s and a precision level of 0.02mmHg is recommended.
3.11 Charging Refrigerant 3.11.1 Calculating additional refrigerant charge Calculate the added refrigerant according to the diameter and the length of the liquid side pipe of the outdoor unit/indoor unit connection. If the length of the liquid side pipe is less than 15 meters it is no need to add more refrigerant, so calculating the added refrigerant the length of the liquid side pipe must subtract 15 meters. Table 3-3.
… box continued from previous page Step 4 ▪ Open the three valves on the pressure gauge to begin charging refrigerant. ▪ When the amount charged reaches R (kg), close the three valves. If the amount charged has not reached R (kg) but no additional refrigerant can be charged, close the three valves on the pressure gauge, run the outdoor unit in cooling mode, and then open the yellow and blue valves.
4 Water Pipework 4.1 Water Circuit Checks Hydronic box are equipped with a water inlet and outlet for connection to a water circuit. Heat Pump Split units should only be connected to closed water circuits. Connection to an open water circuit would lead to excessive corrosion of the water piping. Only materials complying with all applicable legislation should be used. Before continuing installation of the unit, check the following: ▪ ▪ ▪ ▪ ▪ ▪ The maximum water pressure ≤ 3 bar.
4.3 Water Circuit Connection Water connections must be made correctly in accordance with the labels on the hydronic box, with respect to the water inlet and water outlet. If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following when connecting the water circuit: ▪ Use clean pipes only. ▪ Hold the pipe end downwards when removing burrs ▪ Cover the pipe end when inserting it through a wall to prevent dust and dirt entering.
Uninhibited glycol will turn acidic under the influence of oxygen. This process is accelerated by presence of copper and at higher temperatures. The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system. It is of extreme importance: ▪ That the water treatment is correctly executed by a qualified water specialist. ▪ That a glycol with corrosion inhibitors is selected to counteract acids formed by the oxidation of glycols.
5 Electrical Wiring 5.1 General Notes for installers Caution ▪ All installation and wiring must be carried out by competent and suitably qualified, certified and accredited professionals and in accordance with all applicable legislation. ▪ Electrical systems should be grounded in accordance with all applicable legislation. ▪ Overcurrent circuit breakers and residual-current circuit breakers (ground fault circuit interrupters) should be used in accordance with all applicable legislation.
