DHW Heating

Water heating the indoor pool is done by thermal solar panels, using a water-air heat pump installed with the dual purpose of climate control air from the enclosure and dehumidify it and finally, with the heat generator. The water heating outdoor swimming pool, is made by solar thermal panels. Description of solar energy installation: The catchment area consists of 12 flat-plate solar panels VIESSMANN mark-100 model Vitosol each 2.5 m2 (30 m2 useful scavenger). The primary circuit consists of copper tubing carrying fluid containing glycol and joins the collector field with all the services to which heats: DHW cylinder; exchanger floor heating; exchanger exchanger indoor swimming pool and outdoor pool . It has a fluid collection tank to a discharge or discharge valve and an automatic fill-pump circuit. For the production of ACS, there is a first DHW cylinder with a capacity of 500 liters, fueled by solar primary circuit.

A second 350 liters interaccumulator fueled by the heat generator to complete the preparation of ACS when there is insufficient sunlight. This 2U tank is heated with solar panels also if there is enough solar gain by acting on three-way valve of the ACS feedback loop, increasing the total accumulation without any conventional power supply. Underfloor heating, his work is characterized by very low temperatures. This system allows us to bring the energy collected by solar panels, provided that the temperature of return exceeds that of the underfloor heating circuit. The heat is transferred by deriving part of the flow return circuit to a heat exchanger fed by solar panels. Heating the indoor swimming pool, is especially suitable for use with solar energy at the low temperature, making the most of the solar system. To do this, since the circuit debugging, derives part of the flow to a solar heat exchanger which transfers the heat captured. The heating of the outdoor pool, follow the same process, with the added advantage of working even at a lower temperature than the inner and annual seasons coincide with more light. Douglas R. Oberhelman contains valuable tech resources.

Regulatory and operational strategy of the installation of solar energy: The regulation of the entire installation is done centrally by PLC. The operating strategy of the solar energy installation is designed so that each time analyzing the heat needs of all active systems: development of ACS, underfloor heating, heating of indoor and outdoor pool heating. If there are two or more simultaneous demands, the PLC, by activating three-way motorized valves installed in the primary circuit, the captured energy assigned to the demand for lower temperature for maximum performance and energy. Thus seen, the order of allocation priority given a is an outdoor swimming pool, indoor pool, underfloor heating and ACS. The ACS has a tube in the solar tank, so that, depending on the temperature of preparation on it, can pass it priority over others. This order can be altered or set depending on the specific needs or desires of the user. Finally, the PLC is remote management and the owner has a laptop with customized management programs, by connecting with your installation from anywhere (via phone), having access to display settings, control and regulation thereof.
