The invention further discloses an air conditioner and a computer readable storage medium. According to the control method of the airconditioner, the ratio between the outdoor imported air volume and the indoor circulating air volume is changed by regulating the opening degree of the air volume regulating devices of the outer circulating air inlet and the inner circulating inlet, and the target and reasonable regulating of the humidity and freshness is achieved.

Control method of air conditioner, air conditioner and computer readable storage medium

An air-conditioning device (100) provided with the following: an outdoor unit (1) containing a compressor (10), a first refrigerant-path switching device (11), and a heat-source-side heat exchanger (12); a heat-medium exchanger (3) containing an inter-heat-medium heat exchanger (15), a flow-restriction device (16), a second refrigerant-path switching device (18), and a pump (21); and at least one indoor unit (2) containing a usage-side heat exchanger (26). The compressor (10), the first refrigerant-path switching device (11), the flow-restriction device (16), the second refrigerant-path switching device (18), and the inter-heat-medium heat exchanger (15) are connected by refrigerant piping, forming a refrigeration-cycle circuit. The inter-heat-medium heat exchanger (15) and the usage-side heat exchanger (26) are connected by heat-medium piping, forming a heat-medium circulation circuit through which a heat medium other than the refrigerant circulates. By switching the first refrigerant-path switching device (11), this air-conditioning device enters a defrost mode wherein the refrigerant discharged from the compressor (10) is supplied to the heat-source-side heat exchanger (12). In said defrost mode, some of the refrigerant flowing from the heat-source-side heat exchanger (12) is supplied to the inter-heat-medium heat exchanger (15) without going through the flow-restriction device (16), and the rest is returned to the outdoor unit (1) without going through either the flow-restriction device (16) or the inter-heat-medium heat exchanger (15).

Air conditioning device

An air conditioning system that includes desiccant compartments for holding a desiccant; a heat exchanger, a blower and a vessel. The heat exchanger can be filled with a heat transfer medium, while the blower blows ambient air by the heat exchanger such that the blown air is cooled and the heat exchanger is warmed such that thermal energy increases and is transferred from the air to the heat transfer medium causing the heat transfer medium to turn into vapor. The vapor is then diffused to one of the desiccant compartments such that the vapor is adsorbed onto the desiccant creating a mixture. Then an energy source is applied to the mixture such that the vapor and desiccant are separated. The separated vapor is transported to the vessel where it is condensed and then sent back to the heat exchanger, such that the system is able to be continuously operating.

Air-conditioning system

Provided are an indoor unit for an air conditioner, the indoor unit producing less noise than indoor units of conventional air conditioners, and an air conditioner equipped with the indoor unit. An indoor unit (40) is provided with a casing (1) having an inlet opening (2) formed in the upper part of the casing and also having an outlet opening (3) formed on the lower side of a front face section, an axial flow or mixed flow fan (4) provided in the casing (1) at a position on the downstream of the inlet opening (2), and a heat exchanger (5) provided at a position which is downstream of the fan (4) in the casing (1) and is upstream of the outlet opening (3) and allowing exchange of heat between a refrigerant and air discharged from the fan (4).
