When heating up the water in the lower inner part of a hot water tank by a heat pump unit, a control unit stops the heat-up operation while leaving the hot water in an amount corresponding to the residual water capacity in the hot water tank detected by water level thermistors. In the heat-up operation in the hot water tank, the residual hot water capacity in the tank is first detected, then the heat-up operation is stopped when the residual hot water reaches an amount corresponding to the detected residual hot water capacity. At this point, the hot water is stored so that the hot water newly heated up by the heat pump unit is laid above the residual hot water for the preceding day. Consequently, the reduction in the operating efficiency of the heat pump cycle is prevented without supplying the medium-temperature residual hot water to a condenser.

This invention describes a bioerodible fibrin material which is obtained by mixing fibrinogen and thrombin reconstituted or diluted with a particular high tonic strength medium, free of calcium. Such a fibrin-based biomaterial develops a tight structure with thin fibers and small pore size suitable for use as an anti-adhesion barrier. In this invention, thrombin is no longer the variable which governs the tightness and the porosity of the fibrin material obtained, but still controls the clotting time. The mechanical behavior, high-water capacity, and releasable retention properties for therapeutic agents of this fibrin structure causes the fibrin material to be ideally suited for use as a drug delivery device, capable of delivering proteins, hormones, enzymes, antibiotics, antineoplastic agents and even cells for local and systemic treatment of human and non-human patients.

A humidifier has a first sealable reservoir feeding water to a second reservoir communicating with ambient atmosphere. A blower is adapted to blow a stream of air through the humidifier to ambient atmosphere, such that the stream of air picks up water vapor from any water that may be in the second reservoir. A feeder valve feeds a quickly-evaporable quantity of water from the first reservoir into the second reservoir. The quickly-evaporable quantity of water in the second reservoir is substantially smaller than the water capacity of the first reservoir. A dry-out mechanism shuts off the feeder valve upon a user command and continues to run the blower at least until the quickly-evaporable quantity of water has evaporated to an extent effective in inhibiting the growth of microorganisms in the microorganism-vulnerable reservoir.
