HEAT+: Optimized Heat Interface Unit (HIU) for Central Space Heating and Domestic Hot Water Preparation Systems with a Dedicated Electronic Equipment

Description of the project offered: 
An Italian Sme located in Lombardy is developing a Heat Interface Unit that provides on-demand heating and hot water by two integrated heat exchangers, whose instantaneous power is adjusted by valves modulated by smart electronic equipment.
In multi-dwelling residential complexes, central heating solutions are more and more encouraged, since using a number of local heat generators proved to be less cost effective and more polluting than using a single appliance of equal efficiency. Furthermore, local solutions do not allow to easily integrate different energy sources, like renewable or alternative sources. To ensure each user the necessary independence, a heat interface unit (HIU) can be installed at the entrance of each household including regulation, control and metering devices. HIUs equipped with heat exchanger are particularly interesting because they provide on-demand hot water, prepared instantaneously for each user without the need for cylinder storage.
The purpose of this proposal is to develop and put forth an optimised HIU fulfilling the needs of a modern household. Solutions adopted to optimise its operation include the possibility to exert differential pressure control over different segments of the system, the use of two heat exchangers instead of just one (indirect HIU), and the control of domestic hot water temperature and heating fluid temperature by means of modulating two-port valves. In this configuration, each valve is installed on the primary side of the relative heat exchanger and adjusts the boiler flow rate so to keep the secondary fluid flow temperature stable to the desired value. This solution allows to save pumping energy with respect to fixed-flow rate configurations and optimises the temperature difference across the primary side by keeping the return temperature as low as possible, which improves the operation of condensing boilers and is often a prerequisite by district heating companies or contractors.
The use of two-port valves for temperature control requires the development of a dedicated electronic equipment that must be capable of independently managing the services and to easily interconnect with smart systems for remote control. 
System performances will be assessed by a full test campaign including field testing.
Making the product known and giving the operators information on system requirements, correct use and implications of choosing this system arrangement are of fundamental importance, too. This information process can be tackled by transparent advertising campaigns and by widespread training sessions tailored to all the stakeholders involved – designer, installer, servicer and end user.
Project's aims
• Design of the mechanical and hydraulic equipment: development and engineering of components, with particular attention to control valves; design of the assembly 
• Development of a dedicated electronic control equipment, consisting of electronic servomotors, sensors and controllers
• Prototype manufacturing
• Full test campaign to assess the HIU performances and to define the product in detail, including field testing
• Supply chain definition
• Production definition
• Creation of technical, marketing and advertising documentation
• Planning of training sessions targeted at technical designers, installers, servicers
• Creation of installation, commissioning, technical assistance after-sale services
• Definition and delivery of information sessions targeted at the end users.
