A system for conditioning air circulated from an interior of a building includes a refrigerant path, an air-cooled condenser in the refrigerant path, a water-cooled condenser in the refrigerant path that transfers heat from refrigerant in the refrigerant path to the building water, an evaporator in the refrigerant path, and a control system. The control system moves the system between operation of the air-cooled condenser and the water-cooled condenser based upon predetermined system conditions.

An adsorptive heat transformation arrangement includes at least two adsorbers which are connected to at least one pump, an evaporator, and a condenser, a heat store comprising a plurality of horizontal loading and unloading devices for simultaneously stratifying and/or withdrawing a heat transfer fluid, and two or more supply lines fluidically coupled to one another and fluidically coupled to at least one adsorption module. Each horizontal loading and unloading device can be supplied with heat transfer fluid via at least one of the two or more supply lines.

A water heater is provided having a sorption based reactor that is integrated into a water tank. The water heater is operated between an adsorption cycle and a desorption cycle. During the endothermic desorption cycle, a primary heat exchanger is used to transfer heat from a condensing primary fluid that was vaporized from the sorbate to water in the tank. A charging heat transfer system supplies heat for the vaporization during endothermic desorption cycle. During the exothermic adsorption cycle, a secondary heat exchanger is used along with a secondary fluid to transfer heat generated by adsorption of the primary fluid to water in the tank. An evaporator provides for vaporization of the primary fluid during the adsorption cycle. Substantial improvements in energy efficiency can be achieved.

A hot-water heat pump that is capable of reducing installation costs and installation space and also reducing the heating time of a hot-water route, and a method of controlling the same are provided. The hot-water heat pump (1) is provided with a hot-water-heat-pump main unit (2) that includes a thermal output heat exchanger that absorbs heat from a heat-source route and outputs heat; hot-water route (5 and 6) that receive heat outputted from the thermal output heat exchanger; a three-way valve (4) provided in the outlet-side hot-water route (6); and a controller that controls the hot-water-heat-pump main unit (2) and the three-way valve (4), wherein the controller controls the size of openings of the three-way valve (4) so that a portion of the outlet-side hot-water route (6) leading out of the thermal output heat exchanger is guided to an upstream side of the thermal output heat exchanger.
