The invention discloses an energy-saving environmentally-friendly civil indoor
refrigeration system, which comprises a shell, a
refrigeration water tank, a temperature sensor, a cold-heat exchange device, a refrigerating unit, a circulating water inlet
pipe, a circulating water outlet
pipe, an automatic circulating water pump, a circulating water pump temperature-controlled switch and an indoor cold-
heat exchanger, wherein the temperature sensor carries out real-time detection of the temperature of the water inside the
refrigeration water tank, the cold-heat exchange device is arranged inside the refrigeration water tank, the refrigerating unit refrigerates the water inside the refrigeration water tank, the circulating water inlet
pipe and the circulating water outlet pipe are communicated with the inside of the refrigeration water tank, the automatic circulating water pump is arranged in the circulating water inlet pipe or the circulating water outlet pipe, the circulating water pump temperature-controlled switch correspondingly controls the on and off of the automatic circulating water pump according to a
signal detected by the temperature sensor, and the indoor cold-
heat exchanger is arranged indoor; the refrigeration water tank, the circulating water inlet pipe, the circulating water outlet pipe and the indoor cold-
heat exchanger form a cold-heat exchange circuit using water as a medium; and the refrigeration water tank is provided with an automatic exhaust device communicated with the inside of the refrigeration water tank. The energy-saving environmentally-friendly civil indoor refrigeration
system is simple and reasonable in structure and good in refrigeration and cooling effects, and can effectively solve a plurality of practical problems in the refrigeration process of the prior air-cooled
air conditioning unit.
