Description

Ground energy closed cycle formula refrigeration central air-conditioning
Technical field the utility model relates to a kind of utilization ground high efficiency of energy energy-saving cold and heat switch type central air-conditioning.
The mode of the present central air-conditioning of background technology refrigeration in summer employing is air-cooled or water-cooled all be unable to do without evaporimeter, condenser, throttling arrangement and compressor and chemical refrigerant.The cold-producing medium working medium of evaporimeter of flowing through absorbs from turning to the gas refrigerant that latent heat (indoor air is cooled simultaneously) is evaporated to low-temp low-pressure behind the heat in the indoor air, enter the suction inlet of compressor, when compressor outlet comes out, become HTHP gas phase working medium and enter condenser, latent heat (outdoor air or water is heated simultaneously) is emitted in cooling in condenser becomes liquid state, and the vapour-liquid two-phase working substance that becomes low-temp low-pressure through throttling arrangement flows through evaporimeter again.By the effect of compressor, cold-producing medium carries out the circulating heat absorption heat release from the evaporimeter to the condenser, indoor heat is siphoned away take the outdoor realization air conditioner refrigerating in summer that leaves to.General 1: 2.77-2.8 of wind regime formula central air-conditioning Energy Efficiency Ratio by said process refrigeration, freeze general Energy Efficiency Ratio 1: 4 of water resource heat pump central air-conditioning, the both need exhaust a large amount of electric energy, complex structure, investment is big, the moving expense height of operation, the chemical refrigerant of use has certain pollution to environment.
The power consumption height had pollution to environment when summary of the invention freezed for solving present central air-conditioning summer, and investment is big to be waited not enoughly, and the utility model provides a kind of utilizations ground energy closed cycle formula central air conditioner system of freezing.
The technical scheme that its technical problem that solves the utility model adopts is: pumped well is arranged, inverted well, heat exchanger, terminal fan coil, and by the well water upper hose, well water recharges pipeline, terminal fan coil outlet pipeline, terminal fan coil inlet pipeline connects, immersible pump is arranged in the pumped well, link by the well water upper hose and to connect well water again behind the heat exchanger and recharge pipeline, constitute energy water loop, a ground, terminal water-circulating pump on terminal fan coil and the terminal fan coil outlet pipeline connects heat exchanger, connect terminal fan coil inlet pipeline again, constitute terminal circulation waterway.The heat exchange mode of whole central air conditioner system is to be two closed cycle heat exchange modes of medium with water: be divided into terminal water cycle heat exchange and underground water cycle heat exchange.Terminal recirculated water fan coil draw heat (room air is cooled) back water circulating pump endways circulates the recirculated water that absorbs heat through heat exchanger, underground cold water is extracted the heat exchanger that passes through that does not stop out with immersible pump, when two parts water is all by heat exchanger, carry out heat exchange, this moment, the heat of terminal recirculated water was drawn by underground 5 ℃-12 ℃ cold water, and the terminal circulating water temperature that is absorbed heat reduces and returns fan coil (air themperature the is more and more lower) circulation of absorbing heat again again and carry out.The cold water band of heat absorption heat and is recharged underground, all central air-conditioning be fully nature water cold and hot exchange, non-pollution discharge, need not refrigeration machine, energy saving, environmental protection, simple in structure, be 1/7 of present central air-conditioning power consumption, Energy Efficiency Ratio can reach more than the 1:20.This is suitable for the most suitable novel the Northeast and Inner Mongol and underground water at 5 ℃-12 ℃ wide geographic area.
Appended drawings is a ground energy closed cycle formula refrigeration central air-conditioning structural representation, Reference numeral is among the figure: 1, pumped well, 2, inverted well, 3, immersible pump, 4, the well water upper hose, 5, go up the water non-return valve, 6, valve, 7, electric water treatment device, 8, hydrocyclone, 9, filter, 10, heat exchanger, 11, well water recharges pipeline, 12, terminal fan coil inlet pipeline, 13, terminal fan coil outlet pipeline, 14, terminal fan coil, 15, thermometer, 16, Pressure gauge, 17, air bleeding valve, 18, terminal water-circulating pump.
The specific embodiment in the drawings the immersible pump (3) in the pumped well (1) underground low temperature cold water extract out by well water upper hose (4), last water non-return valve (5), valve (6), electric water treatment device (7), hydrocyclone (8), filter (9), again by heat exchanger (10), after turn back in the inverted well (2) through well water water return pipeline (11).
Water in the terminal fan coil (14) is endways under the effect of water circulating pump (18), after passing through heat exchanger (10) again by terminal fan coil outlet pipeline (13), return terminal fan coil again through fan coil inlet pipeline (12), terminal recirculated water and underground low temperature cold water all carry out cold and hot exchange when circulation enters heat exchanger (10), well water is the heat extraction of recirculated water and inverted well back cooling down.
