“…was put forward [4][5][6][7][8], which could make full use of both heating and cooling from the condenser and evaporator to provide the thermal energy for desiccant regeneration. One type of RDC-VC system was called Clean-Air Heat Pump (CAHP) which combined a silica gel rotor with a heat pump [9][10][11][12]. The recirculation air from the conditioned room was mixed with outdoor air to form process air, which was dehumidified and cleaned by the silica gel rotor, then cooled by the evaporator of the heat pump and delivered to the room.…”

“…The condensing heat from the heat pump was adequate for reactivating the desiccant wheel without any additional heat. It was found that the CAHP system saved energy in the range of 5%~59% in the different summer and winter conditions compared with the traditional vapor compression air conditioning system [12], so that the CAHP system could achieve cooling, heating and ventilation in buildings with less energy consumption.…”

In a time of permanent care for environmental protection, energy consumption and conservation of resources, heat pumps are becoming increasingly important as a technology for reducing greenhouse gas emissions while preservation thermal comfort in build environment. This paper presents the experimental results of air-source heat pump in different real operating conditions, as follows: for space heating by low-temperature underfloor heating when the supply water temperature was set at 38°C, or for domestic hot water heating in the storage tank volume of 180 liters at a temperature of 46°C. In the low-temperature underfloor heating mode, the efficiency of the air-source heat pump could be increased if the maximum temperature at the end of the compression process and the condensing temperature were reduced in the initial phase of the heat pump operation. In the domestic hot water heating mode, the efficiency of the air-source heat pump could be increased if the maximum condensation temperature in the final phase of the heat pump operation was limited.
