An air conditioning system () has: a heat pump unit () that heats a room with a vapor compression refrigerant circuit (); a separate heat source unit () that heats a room with a heat source separate from the heat pump unit (); and a control unit () that controls an operation of the heat pump unit () and the separate heat source unit (). As a refrigerant, a flammable refrigerant is sealed in the refrigerant circuit (). When the flammable refrigerant is leaking, the control unit () heats the room with the separate heat source unit () in both cases where a heat pump heating condition is satisfied and where a separate heat source heating condition is satisfied.

Air conditioning system

An HVAC system is provided. Embodiments of the present disclosure generally relate to heat exchangers having tubing with a reduced diameter compared to traditional systems. In one embodiment, a ducted HVAC system comprises an outdoor heat exchanger with tubing that has an outer diameter of eight millimeters (8 mm) or less and an indoor heat exchanger with tubing that has an outer diameter of nine millimeters (9 mm) or less. Additional systems, devices, and methods are also disclosed.

System and method for heating and cooling

An air conditioning system includes: a controller that controls an air conditioner; a thermostat that measures a temperature of an air conditioning target space, changes a contact point to an ON state or an OFF state in accordance with a measurement result, and manages input of a control signal to the controller to control operation of a component of the air conditioner; a connection line group that electrically connects the thermostat and the controller; a relay that switches, to either a conductive state or a cut-off state, at least one of a first connection line that controls a compressor of the air conditioner or a second connection line that controls an indoor fan of the air conditioner, among the connection line group; and a leakage detection sensor that detects refrigerant leakage from the air conditioner, and outputs a signal that controls the relay.

Air conditioning system with refrigerant leak management

An air conditioning system has: an indoor fan that sends air into a room through an air-blowing flow path; a heat pump unit that air-conditions the room with a vapor compression refrigerant circuit; and a separate heat source unit that air-conditions the room with a furnace that heats air by burning fuel or an electric heater that heats air with heat generated by energization. As a refrigerant, a flammable refrigerant is sealed in the refrigerant circuit. A controller controls an operation of the indoor fan, the heat pump unit, and the separate heat source unit. When starting air conditioning in the room with the separate heat source unit, the controller brings a state where the indoor fan is in operation before causing an operation for burning fuel in the furnace.

An indoor unit for an air conditioning device that can increase the strength of a casing of the indoor unit, increase the stability of the indoor unit, and promote cooling of an electric component is disclosed. The indoor unit for the air conditioning device includes a casing formed with an intake air port in a lower portion thereof, and formed with an exhaust air port in an upper portion thereof, a fan arranged inside the casing, and generating air flow from the intake port to the exhaust port, a heat exchanging device arranged below the fan inside the casing to exchange heat with the air taken into the casing from the intake port, and an electric component case provided at a position adjacent to a lateral side of the fan in a circulation space of the air in the casing and configured as a strengthening member of the casing.

Indoor unit for air conditioning device

This application aims at providing a retainer of a cosmetic material and a method of manufacturing a cosmetic tool, which are capable of easily treating the cosmetic material even when decreasing a concentration of skin care ingredients of the cosmetic material produced by freeze-drying. A cosmetic tool () includes: a retainer () to include an annular frame () and a handle () for holding the frame (); and a cosmetic material () to be produced by freeze-drying an aqueous solution of skin care ingredients and fixed in a way that covers an aperture of the frame ().
