Abstract: A heat pump and a control method thereof are provided. The heat pump includes an outdoor unit includes a compressor that compresses a first refrigerant, a first outdoor heat exchanger that exchanges heat between the first refrigerant and outdoor air, an expansion mechanism that expands the first refrigerant, and a second outdoor heat exchanger that exchanges heat between the first refrigerant and a second refrigerant; a first refrigerant pipe that connects the compressor, the first outdoor heat exchanger, and the expansion mechanism, and through which the first refrigerant flows; a pressure sensor disposed in the first refrigerant pipe; a second refrigerant pipe connected to the second outdoor heat exchanger, and through which the second refrigerant flows; an indoor heat exchanger that is disposed in the second refrigerant pipe, and exchanges heat between indoor air and the second refrigerant; and a controller that determines a supply of the second refrigerant by determining a flow rate of the second refrigerant based on surging occurring in a pressure of the first refrigerant measured by the pressure sensor, so that the flow rate of the second refrigerant flowing through the second refrigerant pipe is determined only by the pressure value of the first refrigerant measured by the pressure sensor disposed in the first pipe, thereby determining the flow rate of the second refrigerant without a separate flow sensor.

Abstract: Provided is a mobile terminal. The mobile terminal includes a window, a display disposed on a rear surface of the window to output an image, a terminal body having a front surface on which the window is disposed, and an external cover coupled to an outer surface of the terminal body to protect an outer appearance of the terminal body. The external cover comprises a front cover that covers at least one outer surface of top, bottom, left, and right surfaces of the terminal body and a portion of a front surface of the window. Since the external cover covers a portion of a front surface of the mobile terminal in addition to an outer surface of the mobile terminal, an area for protecting the mobile terminal against an external impact or foreign substances may increase.

Abstract: A heat pump may include a compressor configured to compress a refrigerant, a first temperature sensor provided in heating pipes connected to a heating device that heats an indoor space to sense a temperature of fluid flowing through the heating pipes, and a controller. The controller may be configured to determine whether a boiler is operating to heat an indoor space or is operating to supply hot water based on a sensing value of the first temperature sensor. The compressor may operate when the controller determines that the boiler is not operating to heat the indoor space and/or determines that the boiler is operating to supply hot water.
