The water temperature circulating by the pipes during heating and cooling mode is 52 °C and 7 °C, respectively. For this reason, during heating PCM for cooling is completely in liquid state, while in cooling mode PCM for heating is acting as a solid.
Chilled water systems typically store supply water at 39°F to 42°F, which is compatible with most water chillers and distribution systems. Return temperatures are typically in the range of 55°F to 60°F or higher. Stratified low-temperature-fluid TES systems operate similarly but with lower supply temperatures, typically between 29°F and 36°F.
Heat storage in separate TES modules usually requires active components (fans or pumps) and control systems to transport stored energy to the occupant space. Heat storage tanks, various types of heat exchanges, solar collectors, air ducts, and indoor heating bodies can be considered elements of an active system.
Fig. 25. Application of 600 mm EPS insulation to STES . Solar energy is first used to meet the DHW requirements, and then the space heating requirements (either via the wet underfloor heating system or via the heat exchanger (HX) in the HRV system). Any surplus solar heat is diverted to the STES.
Chilled water is typically sup-plied to air-handling units at 44°F (6.7°C). An ice plant can provide chilled water temperatures at nominal 32°F to 36°F (0 to 2.2°C), and its larger Delta T is wasted.
The amount of energy stored (Eq. (1)) is proportional to the temperature difference, the mass of the storage medium, and its heat capacity: (1) Q = m · C p · Δ T where Cp is the specific heat of the storage material (J/kg·°C), ΔT the temperature gradient (°C), m the mass of storage material (kg).
