摘要： The present disclosure discloses a heating system coupling a passive phase change energy storage sunlight room with an air source heat pump. The heating system includes a passive phase change energy storage sunlight room (7), phase change heat storage units, a to-be-heated room (8), and an air source heat pump air heater arranged between the passive phase change energy storage sunlight room (7) and the to-be-heated room (8), wherein each phase change heat storage unit (11) consists of a plurality of phase change heat storage modules (1). An opening in the front part of each phase change heat storage module faces an interior of the passive phase change energy storage sunlight room, and the phase change heat storage modules located on the top are spliced transversely, and the vent in the top of each phase change heat storage module is connected with the ventilation port of the room.

摘要： The invention relates to a device for storing temperature-controlled fluids, comprising at least one container (20), a Peltier element (30), the hot side (301) of which is in contact with at least one wall (201) of the container (209), at least one device (40) for delivering ambient air to the cold side (302) of the Peltier element (30), and at least one electrical energy source (50, 501, 502) for supplying the Peltier element (30) and the device (40) for delivering the ambient air. For low-loss storage of the fluid in the container (20), the device (40) for delivering ambient air can be operated according to the temperature of the ambient air and the heating capacity of the Peltier element (30) can be controlled according to the currently produced electrical energy of a photovoltaic solar generator (501) forming an electrical energy source. Preferably, times and/or durations of the heat energy emitted from the Peltier element (30) and/or from an accumulator (502) to the fluid can be controlled by a control appliance (6) on the basis of at least one requirements specification stored in the control appliance (60).

摘要： A heat pump has an evaporator for evaporating water as a working liquid so as to produce a working vapor, the evaporation taking place at an evaporation pressure of less than 20 hPa. The working vapor is compressed to a working pressure of at least 25 hPa by a dynamic-type compressor so as to then be liquefied within a liquefier by direct contact with liquefier water. The heat pump is preferably an open system, wherein water present in the environment in the form of ground water, sea water, river water, lake water or brine is evaporated, and wherein water which has been liquefied again is fed to the evaporator, to the soil or to a water treatment plant.

摘要： The inside of a casing constituting an indoor unit of an air-conditioning apparatus is laterally divided by an air passage partition so that an air passage chamber housing an indoor fan and an indoor heat exchanger is defined close to a casing side panel. A space in the casing close to the casing side panel is further vertically divided by a partition having through holes and so that a pipe connection chamber housing parts of the extension pipes, flare joints, and indoor pipes is defined in an upper portion and a pipe draw-out chamber in which the extension pipes are arranged is defined in a lower portion. Gaps between outer peripheries of the extension pipes and inner peripheries of the through holes are filled with insulations.

摘要： An air conditioner, having an outdoor unit and an indoor unit, to perform a heating operation and a defrosting operation, the air conditioner including a detection unit to detect a state of at least one selected between the outdoor unit and the indoor unit and to output the detected value, a controller to determine whether the air conditioner is in a stable state when the defrosting operation is completed and, upon determining that the air conditioner is in the stable state, to control the detected value output from the detection unit to determine entry time of the next defrosting operation, and a storage unit to store a value detected in the stable state. The entry time of the defrosting operation is accurately determined, thereby minimizing the number of times of the defrosting operation during the heating operation.

摘要： A bathroom air-conditioner includes a refrigerant circuit in which a compressor, a radiator, a decompressing mechanism and a heat absorber are connected with one another through a pipe, a circulating air-course, and a ventilating air-course. In the circulating air-course, the radiator and a circulating fan for circulating the air of the bathroom are placed. In the ventilating air-course, the heat absorber and a ventilating fan for discharging the air from the bathroom to the outside are placed. The heat absorber makes the refrigerant absorb heat from the air of the bathroom, and the radiator makes the refrigerant dissipate heat to the air of the bathroom for heating the bathroom. During the heating of the bathroom, when a temperature of the bathroom becomes higher than a given temperature, a controller reduces an air-blow amount from the ventilating fan.
