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

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 apparatus

A gas-injection type refrigeration-cycle device has heat exchanger where refrigerant extracts waste heat from heating devices. In the refrigeration-cycle device, the mode is changed between where lower-pressure refrigerant extracts heat and where intermediate-pressure refrigerant extracts the heat of the hot water. The lower-pressure refrigerant is drawn into compressor, after heat exchanger is set at the lower-pressure side of the refrigeration cycle. The intermediate-pressure refrigerant is introduced into compressor-gas-injection port, after heat exchanger is set at the intermediate-pressure side of the refrigeration cycle. In another aspect, a defrosting mode of outdoor heat exchanger includes a heating mode, and gas refrigerant discharged from compressor flows through condenser without heat exchange. Thereafter, the flow of the gas refrigerant is divided to two portions, and the gas refrigerant of one portion flows into outdoor heat exchanger, thereby defrosting outdoor heat exchanger. The other portion flows into evaporator, thereby heating blown air within an air-conditioning duct by evaporator.

Refrigeration cycle device

PURPOSE:To ensure in a specified range the degree of supercooling of the refrigerant on the inflow side of the first flow rate-controlling device by a method wherein a first degree of supercooling, calculated from the results of detection by a second pressure detective means and a second temperature detective means, is preset and a second flow rate-controlling device is so controlled as to have the degree of supercooling within the targeted range. CONSTITUTION:A second pressure detective means 16 is provided in a discharge line from a compressor 1 and a second temperature detective means 18 is provided at an intermediate point in a line connecting a heat exchanger 13a and a first flow rate-controlling device 6. A decision is made as regards a targeted range of control of the first degree of supercooling, which is the degree of supercooling at the outlet of a heat source machine calculated from the pressure detected by a second pressure detective means 16 and from the result of detection by a second temperature detective means. This targeted range controls a second flow rate-controlling device 12a. Another pressure detective means 16 and other temperature detective means 17, 19 also control the second flow rate-controlling device 12a. Therefore the flow rate of the refrigerant flowing into an indoor apparatus can be controlled appropriately by a first flow-rate controller 6.

Device for air conditioning

PURPOSE:To provide a refrigerating cycle in which sufficient supercooling degree of refrigerant can be early obtained after a compressor is started without depending upon the distribution of refrigerant in a refrigerant circuit and excess refrigerant for obtaining sufficient supercooling degree of the refrigerant can be eliminated. CONSTITUTION:In this refrigerating cycle system, the refrigerant in a second refrigerant tube 24 fed from a heat source side heat exchanger 3 by the start of a compressor 1 is heat exchanged with the refrigerant in an accumulator 6 by a second heat exchanger 7, and additionally heat exchanged with low- temperature and low-pressure refrigerant fed from a second flow controller 9 in a first bypass circuit 8. Accordingly, the refrigerant from the accumulator 6 can be moved by the heat exchange with the refrigerant from the exchanger 3, and the superheat degree of the refrigerant in the tube 24 can be sufficiently obtained. On the other hand, even if there is no supercooling excess refrigerant in the accumulator 6, the refrigerant in the tube 24 is sufficiently supercooled by the heat exchange with the refrigerant of the circuit 8.

Refrigerating cycle system

PURPOSE: To carry out a stable operation of freezing cycle even in the case that a composition of circulating refrigerant is varied by a method wherein a circulating composition sensing means detects a circulating composition of nonazeotropic mixture refrigerant and a calculation control means controls the freezing cycle in reference to the detected result. CONSTITUTION: The number of rotation of a compressor 1 is controlled by a first calculation control device 101 in response to the difference between a pressure value detected by a low pressure sensor 12 and an aimed low pressure value. The first calculation control device 101 controls a degree of opening of a variable adjusting valve 8 in response to the difference between the detected temperature difference across the sub-cool coil 9 and the aimed temperature difference. A aimed capability of the heat exchanger 3 at the heat source is determined in response to the capability of the heat exchangers 51, 52 at the utilization side and then the first calculation control device 101 controls the number of rotation of a blower 14. A second calculation control device 102 controls a degree of opening of each of the expanding devices 41, 42 so as to control capability of each of the heat exchangers 51, 52 at the utilization side.

Freezing device having nonazeotropic mixture refrigerant

PURPOSE:To prevent a compressor from seizing up by providing a means for deciding the degree of the opening of a flow-rate controlling device in a setup in which the opening of the second flow-rate controlling device is altered stepwise by a specified degree in each step on the basis of outputs of a first time-counting means and said means for deciding the degree of the opening of a flow-rate controlling device acts to restore the thus altered opening of the second flow-rate controlling device to the previous degree on the basis of outputs of a second time-counting means. CONSTITUTION:An air conditioner which is capable of operating for both cooling and heating simultaneously is equipped with a first time-counting means 61 for altering, as a first period elapses, the opening of the second flow-rate controlling device 13 and with a second time- counting means 62 for restoring the thus altered opening of the second flow-rate controlling device 13 to the previous degree with the lapse of a second period which is longer than said first period, both the alteration and restoration being effected while the compressor is at work continuously. The opening of the second flow-rate controlling device 13 is altered stepwise by a specified degree in each step on the basis of outputs of the first time-counting means 61, whereas a means 63 for deciding the degree of the opening of the second flow-rate controlling device 13 acts to restore the thus altered opening of the second flow-rate controlling device 13 to the previous degree on the basis of outputs of the second time-counting means 62.
