Evaporators controlled by a thermostatic expansion valve can exhibit an undesirable oscillating behavior, known as hunting. The equations describing the hunting can be characterized by an open-loop transfer function, the coefficients of which are the physical parameters of a refrigeration system. Several known experimental facts are explained theoretically by means of this transfer function, which also provides a starting point for finding new methods to improve the behavior. A particular improvement was verified experimentally.
