Abstract:
PURPOSE: A dehumidifier for a compressor, a single-stage compression-absorption type heat pump system, and a two-stage compression-absorption type heat pump system are provided to reduce damage to the compressor. CONSTITUTION: A dehumidifier for a compressor comprises first and second dehumidification members(11,12), a first flow passage control valve(30), and a second flow passage control valve(20). The first and second dehumidification members absorb the moisture. The first flow passage control valve includes: a first inlet where gaseous refrigerant of low temperature flows; a second inlet where gaseous refrigerant of high temperature and high pressure flows; a first through-hole communicated with the first dehumidification member; and a second through-hole communicated with the second dehumidification member. The second flow passage control valve includes: a first outlet communicated with an inlet of the compressor; a second outlet communicated with an external device; a third through-hole communicated with the first dehumidification member; and a fourth through-hole communicated with the second dehumidification member.

PURPOSE: A thermal energy network system is provided to improve the availability of thermal energy by bidirectionally transporting the thermal energy between first and second thermal bases and to supply required thermal energy to first and second demanding places through the first and second thermal bases. CONSTITUTION: A thermal energy network system a first thermal base(100) and a second thermal base(200). The first thermal base stores first thermal energy using a first heat source(150) and supplies the first thermal energy to a first demanding place(160) for residential and commercial use. The second thermal base stores second thermal energy using a second heat source(250) and supplies the second thermal energy to a second demanding place(160) for industrial use. The first and second thermal bases manage the base load of a thermal energy network. The first and second thermal energies are delivered between the first and second thermal bases as necessary.

Abstract:
PURPOSE: A broadband heat pump system is provided to improve energy availability using heat sources at various temperatures such as a renewable energy source. CONSTITUTION: A broadband heat pump system comprises a heat pump module(310), a heat source supply module(320), and a control unit. The heat source supply module includes multiple heat pumps supplying hot water with a different temperature range. The heat source supply module selectively receives heat sources from one or more heat sources with a different temperature range, and produces the heat source at a desired temperature. The control unit selects one heat pump among heat pumps to be suitable for hot water at a temperature which is required by a demand place, and controls to be supplied with the heat source at the required temperature from the heat source supply module so that the selected heat pump can supply hot water at the required temperature.
