When the surface temperature of the outdoor coil in an air source heat pump (ASHP) unit is lower than both freezing point of water and the air dew point, frost can be formed and accumulated over outdoor coil surface. Frosting affects the energy efficiency, and periodic defrosting therefore is...

Experiments were carried out to investigate the performance of a low-temperature radiant floor heating system with different heat storage materials (sand and phase change material) and heating pipes (polyethylene coils and capillary mat) in the floor structure of a test room. Detailed...

Although many real bargaining situations involve more than one person on each side of the bargaining table, much of the theoretical and experimental research concentrates on two single players. We study a simple extension: bilateral bargaining of four people (two two-person groups) with...

Multiple group memberships are the rule rather than the exception. Within a linear public good game, we experimentally investigate two possible factors that impact the decision to cooperate in a smaller, local or a larger, global group: diverging marginal per capita returns, resulting in...
