Thermal Simulation of Heat Pumps

Thermal Simulation of Heat Pumps

Siemens Digital Industries Software solutions enable Sanden to lower development costs and maximize product performance. Heat pump manufacturer uses Simcenter STAR-CCM+ to rapidly explore design space and bring products to market faster. Gaining market share in an established, competitive market – like the one for domestic hot water heaters – is always a challenge, even when you’re introducing customers to higher-performing, environmentally-friendly product options. In cooperation with advanced development engineers, the thermal engineers at SANDEN Manufacturing Europe (SME) met this challenge by relying on computational fluid dynamics (CFD) simulations to design a key component of an innovative heat pump that uses carbon dioxide (R744) as the working fluid. They used Simcenter STAR-CCM+ software from Siemens Digital Industries Software to perform the simulations. Additionally, the SANDEN engineers performed fully automated CFD-based design explorations – using Design Manager, a multidisciplinary design exploration tool that is part of Simcenter STAR-CCM+ – to determine the optimum shape of the passageways that direct air through the heat pump’s evaporator to maximize the heat transfer that occurs in the evaporator.
