To provide a heat pump apparatus, such as a heat pump water heating apparatus, capable of efficiently supplying high-temperature water by increasing a condensation capacity to a maximum if the outside air temperature is low. The heat pump water heating apparatus is configured to include a first refrigeration cycle and a second refrigeration cycle. The first refrigeration cycle is configured to connect in series a main compressor, a first water-refrigerant heat exchanger, an internal heat exchanger, a first pressure reducing device, and an air heat exchanger. The second refrigeration cycle diverges from the first refrigeration cycle between the first water-refrigerant heat exchanger and the first pressure reducing device, and joins the first refrigeration cycle between the main compressor and the first water-refrigerant heat exchanger. The second refrigeration cycle is configured to connect in series a second pressure reducing device, an internal heat exchanger, a sub compressor, and a third pressure reducing device.
摘要:
A refrigeration cycle apparatus simultaneously performs a cooling operation mode in which a refrigerant from a compressor is caused to flow to an indoor heat exchanger of an indoor unit having a cooling load, and a hot water supply operation mode in which a refrigerant from the compressor is caused to flow to a water heat exchanger of a hot water supply unit having a hot water supply demand. An operation control part switches the control mode of the simultaneous cooling and heating and hot water supply operation mode between a cooling-prioritized mode and a hot-water-supply-prioritized mode according to the relationship between the cooling load and the hot water supply load.

A shaft member is rotatably supported by a stationary-side bracket, a cam member is axially movable, with its rotation being restricted by the shaft member, a biasing element applies a bias in the direction toward the place where the cam member and the bracket contact each other to generate friction torque, and a convex portion and a concave portion are formed on the cam member and the bracket, respectively, to be fitted to each other. Either the convex portion and/or the concave portion is/are shaped such that the torque changes according to the rotation angle of the shaft member, and the biasing element has the inflection point of a spring constant between the maximum and minimum values of the torque.
摘要:
In an image coding apparatus (1), a Hadamard transform unit (11) performs horizontal Hadamard transform on a picture of uncompressed image data (21). The sum total of absolute values of AC component values obtained by the Hadamard transform is calculated as a Hadamard value (23) of the picture. A scene change determination unit (12) determines whether a scene change occurs or not in the picture on the basis of the Hadamard value (23). In a case where a scene change occurs in the picture or where a differential absolute value between the amount of generated codes in a coded GOP and the ideal amount of codes in a GOP is larger than a predetermined reference value, a quantization parameter determination unit (13) determines a quantization parameter (24) of the picture on the basis of the Hadamard value (23) and the target amount of codes of the picture. A coding unit (14) codes the picture by using the determined quantization parameter (24).
