Description
Technical field
The present invention relates to a kind of heat pump type air conditioner set, specifically relate to a kind of evaporative condenser heat pump air conditioner unit, belong to field of Refrigeration and Air-conditioning.
Background technology
Along with heat pump techniques is at nationwide spread, area that some groundwater resources do not enrich, the area that does not possess well-digging, pipe laying cannot adopt the most energy-conservation ground water source heat pump technology at present, conventional net for air-source heat pump units is in summer when refrigerating operaton, the Energy Efficiency Ratio EER of unit is much smaller than water-cooled cold water unit, under thermal extremes condition, the refrigeration efficiency of net for air-source heat pump units is lower than EER; While heating in the winter time, reduce because evaporator surface frosting makes the coefficient of performance of air source heat pump, also will cause heat supply to be interrupted when Defrost operation, its defrosting loss accounts for 10% of heat pump total energy consumption loss.Conventional air source heat pump is especially at a run of wet weather, air humidity is large, when moist sombre regional Winter heat supply frosting serious, must defrosting, heat pump efficiency is lower; Conventional air source heat pump is also subject to geological conditions as the restriction of the thermal source such as underground water, surface water simultaneously, not only needs the expense of well-digging and underground pipe, also needs to set up heat source side high powered water pump simultaneously, has so greatly increased disposable input and operating cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of evaporative condenser heat pump air conditioner unit, utilize the heat in outdoor air, realize refrigeration, heating, domestic hot-water's new technology is provided, it has made up conventional air source heat pump at a run of wet weather, air humidity is large, when moist sombre regional Winter heat supply frosting serious, must defrosting, the shortcoming that heat pump efficiency is low; Be not subject to the restriction of geological conditions simultaneously, do not rely on the thermal source such as underground water, surface water, not only saved that ground water source heat pump air-conditioner need to be dug a well and the expense of underground pipe; Save heat source side high powered water pump simultaneously, greatly reduced so disposable input, and saved the operating cost of daily heat source side high powered water pump.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention: a kind of evaporative condenser heat pump air conditioner unit, comprise casing and the compressor, condenser, evaporimeter, four-way change-over valve, check valve, magnetic valve and the connecting pipe that are positioned at casing, described condenser is made up of housing, solution water pump, automatic medicine adding apparatus, water-collecting tray, heat radiation filler, evaporation coil, water injection nozzle, blower fan; In described housing, set gradually blower fan, water injection nozzle, evaporation coil, heat radiation filler and water-collecting tray from top to bottom, between lower housing portion water-collecting tray and heat radiation filler, be provided with air inlet port; One end of described evaporation coil is connected with the b of four-way change-over valve end, and the other end is connected with one end of evaporimeter by two-way heating power expansion valve, the first check valve; Described solution pump intake is connected with water-collecting tray, delivery port is connected with water injection nozzle; Described automatic medicine adding apparatus and solution water parallel connection of pumps.
The two ends of described the first check valve are arranged in parallel the first magnetic valve.
In described casing, be also provided with heat exchanger, one side two ends of this heat exchanger are connected with evaporimeter, are connected between two-way heating power expansion valve and the first check valve by the second check valve by the second magnetic valve respectively, and the two ends of opposite side connect respectively water-collecting tray and the delivery port that is connected solution water pump by the 3rd magnetic valve.
Beneficial effect of the present invention: 1, energy-saving effect is remarkable: in winter, the Performance Ratio air-cooled heat pump of extraction environment low grade heat energy is stable, without frosting puzzlement, whole winter unit average Energy Efficiency Ratio more than 3.2; Summer, because the heat-sinking capability of evaporative condenser is stronger than cooling tower, play the effect of high-efficiency cooling tower, main frame Energy Efficiency Ratio is more than 4.5; The whole year is comprehensively energy-conservation more than 40% than wind-cooling type heat pump unit; 2, be not subject to the restriction in geological conditions and place: do not rely on the thermal source such as underground water, surface water, be not subject to the restriction of geological conditions, floor space is little; 3, stable, the life-span is long: the thermal source of use in winter is the airborne low grade heat energy that relative humidity is higher, and the stable and evaporating temperature of evaporating pressure, all higher than wind-cooling type heat pump, makes whole heat pump have wider range of operation; Summer, use had enough disengagement areas can bear moment peak air conditioner load, and coolant water temperature is low, and efficiency is high; 4, system is simple: need not consider water resource heat pump ground cooling and heating load equilibrium in summer in source winter, also need not consider the problem of auxiliary electrical heater and defrosting in winter, single-machine capacity scope is large; 5, cost performance is high: adopt this product, one-time investment is low, the one-time investment of ordinary central air-conditioner, the enjoyment of water source heat pump air-conditioner, the expense of having saved water source heat pump air-conditioner well-digging and underground pipe; Saved heat source side high powered water pump simultaneously, not only disposable less investment, and saved the operating cost of daily heat source side high powered water pump.
