For the first time ever, Odds Farm Park is using renewable energy to heat their indoor Playbarn Gallery and children’s soft play area. Generously donated by Ice Energy, the new heating system releases stored solar energy held up to 85 metres beneath ground.
Stage 1 Odds Farm Park have 2 pipes installed 85 metres underground that contain a water/glycol mix at a low temperature. Below ground the surrounding soil is at a higher temperature, typically 12°C and gently warms the glycol mix as it is pumped around the ground loop.
Stage 2: As the liquid leaves the ground, it is fed into a heat exchanger that takes the heat out of the liquid and returns the cooled liquid to the pipe for it’s next cycle.
Stage 3. The heat is moved into the compressor which increases the heat of the gas by reducing its volume. Temperatures of between 75°C and 125°C are achievable through this process.
Stage 4. Feeding the hot gas through a condenser allows the gas to turn back into a liquid. As it condenses it cools and releases its heat through a heat exchanger, directly into the central heating system.
Stage 5: To release the pressure in the Condenser, an expansion valve is used.
