An outdoor unit of an air-conditioning apparatus, wherein the outdoor unit has a control box and an electrical box accommodated therein, in the control box, devices serving as a controller configured to control refrigeration cycle-related devices are accommodated, and in the electrical box, devices including a thermal relay are accommodated, the devices producing a smaller amount of heat compared to the devices accommodated in the control box, the electrical box being formed separately from the control box.

Outdoor unit of air-conditioning apparatus

A hot-water supply and heating system includes: a first pump that circulates a first heat medium between a heat source unit and a heat-medium heat exchanger; a second pump that causes a second heat medium to flow between a load-side device and the heat-medium heat exchanger; a first temperature sensor that detects a primary fluid temperature that is a temperature of the first heat medium that flows out of the heat source unit; a heat-source-unit controller; and a pump controller. The heat-source-unit controller transmits information indicating the heating capacity of the heat source unit reaches an upper limit value to the pump controller, when it is determined that the primary fluid temperature is lower than a target temperature and the heating capability of the heat source unit is equal to the upper limit value. The pump controller reduces an operation frequency of the second pump when receiving the above information.
