SPH / SPH-R

HOW DOES IT WORK?
Air accumulates heat energy throughout the year as a result of solar radiation, water and wind. Therefore, this natural element represents an inexhaustible, clean and most importantly a free source of energy, which can now be exploited thanks to thermodynamic heating, also known as aerothermic heating. The Airwell SPH / SPH-R Split air to water heat pump range, enables this natural form of heat energy to be transferred into the residential environment: energy saving, comfort and respect for the environment are the primary advantages of this technology.

Technical Description

Introduction

The SPH and SPH-R split heat pumps complete the MCH and RCH packaged heat pumps by offering products that avoid the necessity of protecting the water circuits against freezing. All the technical advantages that have contributed the success of the packaged heat pumps are retained in the SPH and SPH-R models, i.e. :

Bodywork and frame

The steel bodywork is coated with oven-hardened epoxy paint. Indoor unit : Removable bodywork panels on all sides of the unit provide easy access to hydraulic and refrigerant circuits as well as electrical cabinet. When fully closed, the bodywork structure complies with IP 24 protection requirements. Outdoor unit : The base of the outdoor unit has large openings beneath the exchanger coil for effective condensate water or defrosting water drainage.
Genuine heat pump system design, as opposed to a simple reversible chiller. Simplified refrigerating circuit, with an easily-accessible electrical cabinet for maintenance purposes and a regulation system designed for maximum heating comfort and economy. Readily-available, premium quality components. Coaxial heat exchanger selected for its excellent performance and low sensitivity to clogging. Use of R407C refrigerant fluid to obtain high outlet water temperatures for applications in conjunction with a hot water boiler.

Compressors

The Scroll type compressors are deigned to provide a high output at low noise levels, and are maintenance-free. Vibration-absorbing pads under the compressor prevent vibrations being transmitted to the unit bodywork. As an option, the compressor can be encased in a soundproof jacket.

Scope of application

SPH model : This type of heat pump is intended for new homes equipped with under-floor heating/cooling, fan coil or radiator systems. These units are heat pumps with integrated 2 kW+4 kW additional electrical heating systems. SPH-R model : Intended to operate in conjunction with a hot water heating boiler, these models only provide heating. The electrical cabinet is pre-wired for regulation management kits (option) to control heating in conjunction with a hot water heating boiler. The SPH and SPH-R heat pumps are composed of two units linked by refrigerant piping. The outdoor unit contains only :

Water heat exchangers

Of the coaxial type with counter-current circuitry for winter mode, the heat exchangers provide excellent heating performance while offering all the proven advantages of coaxial design: low sensitivity to clogging and freezing, as well as low pressure losses.

Air heat exchangers

Exchangers are finished with a hydrophilic coating to assist condensation water runoff. Exchanger fins are of the slat-free waffle type to prevent clogging and maintain performance during sub-zero conditions and to reduce defrosting time and frequency : defrosting at only three hours intervals at an outdoor temperature of 2 C and a water temperature at 40 C - 45 C.

2 or 3-row finned coil, 2 fans, Liquid tank, Thermostatic expansion valve (heating function) and capillaries (cooling and defrosting function).
Reinforced polypropylene axial fans with an optimised blade profile that run at low speeds to provide the required airflow at extremely low noise levels. The fully-closed motor is maintenance-free and equipped with automatic reset thermal overload protection. The fan blades are protected by plastic grilles in accordance with health & safety standards. An all-seasons control system acts on fan speed to maintain chilled water production condensing pressure (Summer mode on SPH version) down to outdoor temperatures of 10 C, and to limit the evaporator load in heating mode under high outdoor temperatures.
All other equipments are located in the indoor unit. The refrigerant linking pipes are of "to be brazed" type. They are not supplied with the unit. The heat pump is charged for use with 8-meter refrigerant pipes.
Advantages of split heat pumps
The outdoor unit has only fans. Its sound level is considerably low, causing then a minimum trouble with the neighbourhood. The compressor sound treatment is easier in the indoor unit itself located in the technical room. All the electrical components are inside : ease of wiring and maintenance. The discharge line stays confined in the indoor unit; no heat losses unlike the discharge inside the linking pipes between the two units. During the off periods, the compressor is not in the cold part of the circuit, there is no risk of liquid accumulation; thus, less risks at re-starting. Controls, measurements, interventions on the electrical and refrigerant components are possible whatever the weather conditions.

Refrigerant circuit

The indoor and outdoor units are tested together and matched for shipment. The refrigerant charged at the factory is suitable for linking pipes up to 8 metres. For higher distances, complete the charge on the basis of 30 g of R407C per metre. Maximum pipe length : 30 metres. The pre-charged and factory-checked circuit includes a dryer filter, a thermostatic expansion valve, as well as high and low pressostats. The exchanger circuitry is designed for counter-current flow in heating mode in order to optimise unit performances in the most frequently used mode, i.e. winter mode.

Technical Description (continued)
Pipe insulation (not supplied)
The heat pump installed in the house is linked to the outdoor unit by 2 refrigerant pipes. The pipe of smaller diameter (12.7 mm) is for "liquid" line. That of bigger diameter (19 mm for models 08 and 10, 22 mm for model 12) is for "gas" line. In heating mode of the heat pump operation, the refrigerant runs through the "gas" lin at a temperature lower than 3 K in comparison with outdoor air. The rise of this temperature during the refrigerant passage to the compressor, located inside the indoor unit, decreases the system performance of about 1% for each degree of increase. It is thus very important to insulate this tube with a quality product in conformity to the EN ISO 8497 standard (thermal conductivity <0.036 W/m.K). In addition, the insulation shall be thick enough notably inside the house, the most critical part, since it is the hotest part of the piping. The following data, for an evaporating temperature of 1 C and a condensing temperature of 40 C, allow the insulation thickness to be calculated precisely : SPH 08, mass flow= 40.4 g/s SPH 10, mass flow= 58.9 g/s SPH 12, mass flow= 72.4 g/s In pratice, we recommend an insulation thickness of 13 mm ( of insulating material is 0.036 W/m.K). With this thickness, the capacity drop, for a pipe length of 30 metres, is lower than 4%. Concerning the "liquid" line (1/2"), the refrigerant circulates inside the tube at a temperature lower than 5 K in comparison with the condensing temperature; thus, at a temperature higher than indoor and outdoor air. The liquide cooling in heating mode does not lead to any capacity loss. However, in cooling mode, we recommend an insulation thickness of 9 mm for the "liquid" tube in order to limit the capacity losses.

Controlling condensing pressure in the summer (SPH version). Controlling evaporation pressure (output regulation) in heating mode.

Regulation

SPH version

Summer/Winter mode selection via the ambience thermostat :

SPH-R version

This version of the heat pump system only provides heating in conjunction with a hot water boiler. The SPH-R can be connected to an ambience thermostat or to a regulation management kit.

Summer regulation

The regulator maintains the temperature of the inlet (return) water flowing to the unit at the requested "COO" set temperature. Acceptable temperature range for the set inlet (return) water temperature in summer mode : 12 C to 25 C. In addition, the ambience thermostat stops the unit when the ambient air temperature reaches the value requested by the thermostat.
Case of connection with an ambience thermostat only
In case of use with a thermostat alone, without the regulation management kit, heat pump regulation does not take account of boiler management. The regulator maintains the temperature of the inlet (return) water in accordance with a water logic based on outdoor temperature. All the various parameters of this water logic can be set, i.e. : - Setting the outdoor temperature used as the base benchmark for the water logic. Above this benchmark outdoor temperature, the inlet (return) water temperature is maintained at the "HEAT" set temperature point. - Setting the outdoor temperature offset between the beginning and end of temperature compensation. - Setting the rise in inlet (return) water temperature between the beginning and end of temperature compensation. The heating function remains permanently under the control of the ambience thermostat that has priority in stopping the unit when the ambient air set temperature is reached. The SPH-R versions are equipped with an "automatic forced shutdown" function that limits the use of the unit depending on the outdoor temperature. This shutdown temperature is set at the factory at -5 C or -15 C depending on whether it is installed with an under-floor heating or radiator system. These values are increased to -10 C and -20 C with the ZH compressors option.

Winter regulation

The regulator maintains the temperature of the inlet (return) water in accordance with a water logic based on outdoor temperature. All the various parameters of this water logic can be set, i.e. : - Setting the outdoor temperature used as the base benchmark for the water logic. Above this benchmark outdoor temperature, inlet (return) water temperature is maintained at the "HEAT" set temperature point. - Setting the outdoor temperature offset between the beginning and end of temperature compensation. - Setting the rise in inlet (return) water temperature between the beginning and end of temperature compensation.

Functions provided by the regulation management kit : Heating mode selection in relation to outdoor temperature - Above the factory-set balance point of +4 C (specific value for each installation to be inputted into the regulation management kit), the unit operates on its own. - Below the balance point, the unit continues to operate with priority over the boiler. Furthermore, if the inlet (return) water temperature does not correspond to the value calculated by the controller, the boiler is solicited as additional heating. - Below the outdoor temperature for unit forced shutdown, only boiler operation is authorised. Recap of forced shutdown temperatures for the SPH-R : - Standard compressors : For radiator application : -5 C For under-floor heating application : -15 C - ZH compressors (option) : For radiator application : -10 C For under-floor heating application : -20 C

Outdoor temp. [C]
If the inlet (return) water temperature calculated by the water logic cannot be reached by the compressor operating on its own, the regulator switches on the additional electrical heating system. The additional electrical heating system is divided into two stages, i.e. 2 kW + 4 kW. These stages can only be triggered when the following conditions are present : - Difference between the ambient temperature and the set thermostat temperature greater than 0.9 C. - Outdoor temperature below outdoor thermostat set temperature. (KA6). This outdoor thermostat set temperature is adjustable (factory setting : +5 C). There is a 30 minute time delay before the second stage (4 kW) is triggered. Emergency function : An "emergency heating" switch located near the regulator is used to engage the additional electrical heating resistances based solely on water logic, without any other condition. The ambience thermostat has priority for stopping the unit when the ambient air set temperature is reached.

Regulation (continued)
SPH-R shutdown control in relation with off-peak electricity tariffs With the aid of a dry contact switch to be connected in the regulation management kit box, the unit can be shut down during "EJP" or "TEMPO" days (French special electricity tariff days for high energy consumers). During these peak periods the boiler can be controlled by outdoor temperature conditions. Zone valve management The regulation management kit controls the zone valve available as an option. This three-way, ON-OFF valve creates a bypass to prevent water reheated by the unit entering the boiler when the latter is not in operation. Emergency heating function management The regulation management kit includes an "emergency heating" switch that renders boiler operation independent of outdoor conditions.
Unit operating mode when connected with the regulation management kit
When the SPH-R is installed with the regulation management kit and the ambience thermostat supplied with the kit, its operation is identical to that described in the previous paragraph : Case of connection with an ambience thermostat only.
Boiler regulation operating mode
The boiler can be linked to the ambience thermostat supplied with the regulation management kit or left under the control of its own regulation system. Comment : The thermostat supplied with the regulation management kit can be of the standard hardwired connection (3 wires) type or with an optional wireless (radio) link.
