Description
Technical field
The utility model relates to the integrated switching device shifter of a kind of full-liquid type handpiece Water Chilling Units exterior line, especially a kind of by integrated the integrated switching device shifter of full-liquid type handpiece Water Chilling Units exterior line, when installation as long as by pipeline exact connect ion, when pipeline switches without by manually or electrically operated valve switch adapter.
Background technology
Earth-source hot-pump system is that the novel energy that utilizes superficial-layer geothermal energy to carry out heating and refrigerating utilizes the eco-friendly power source of technology to utilize system.Earth-source hot-pump system normally shifts in underground heat or cold to needed place, also utilize the heat storage and cold accumulation ability that underground is huge, source, ground in winter is transferred to heat in building from underground, transfer to underground cold in building summer again, a year forms a cooling and heating circulation system, realizes the function of energy-saving and emission-reduction.
Under refrigerating state, the compressor in earth source heat pump unit does work to refrigerant, makes it carry out the circulation of vapour-liquid conversion.Evaporation by refrigerant in evaporimeter will be circulated entrained heat absorption to refrigerant by fan coil, at refrigerant circulation simultaneously again by the condensation of refrigerant in condenser, circulate by water heat absorption entrained refrigerant, finally by water loop jump to ground water, underground water or soil.Constantly be transferred in underground process at indoor heat, by fan coil, taking the form of 13 DEG C of following cold wind as room cooling.
Under heating state, compressor does work to refrigerant, and by reversal valve, refrigerant flow direction is commutated.Absorb the heat in surface water, underground water or soil by underground waterway circulating, by the evaporation of refrigerant in condenser, by the heat absorption in waterway circulating to refrigerant, in refrigerant circulation, again by the condensation of refrigerant in evaporimeter, circulated heat absorption entrained refrigerant by fan coil.Constantly be transferred in indoor process at underground heat, with the form of more than 35 DEG C hot blast to indoor heating.
