The specific embodiment
Fig. 1 is prior art air conditioner structure and operational flow diagram, and solid line is the heat exchange waterway pipe among the figure, and diagram preheating desuperheating coil 1 is heated by thermal source 7 with heat(ing) coil 3, and cooling coil 2 is lowered the temperature by cold water source.Dotted line is a gas path pipe among the figure; It is thus clear that outdoor new wind 6 is with after the indoor return air of part that clean air conditioner room 5 return air inlets 5.2 are drawn mixes; Through 1 preheating of preheating desuperheating coil, cooling coil 2 cooling and dehumidifyings, be heated to through heat(ing) coil 3 again and supply with clean air conditioner room 5 behind the proper temperature.This summer in winter is unified operational mode; Preheating desuperheating coil 1 is heated by thermal source 7 with heat(ing) coil 3; Cooling coil 2 is by cold water source cooling, do not take into full account winter outdoor new wind-warm syndrome degree and is lower than feed air temperature, dry, need not these characteristics of cooling and dehumidifying; The heat of the indoor return air of part that clean air conditioner room 5 return air inlets 5.2 are drawn is not fully used, and causes repeating cooling and causes waste of energy.
Fig. 2 is one of air conditioner structure and operational flow diagram of the utility model.Visible by figure; The utility model winter is used energy-saving air conditioning; Comprise that the precooling preheat coil 1 that links to each other successively (should be preheat coil here; But in order to narrate convenient and to be beneficial to and the prior art contrast, still with the name of precooling preheat coil). heat(ing) coil 3 is characterized in that: auxiliary cooling coil 4 is equipped with return air inlet 4.1, fresh inlet 4.2 and air-supply outlet 4.3; Clean air conditioner room 5 is equipped with air outlet 5.1 and return air inlet 5.2; Return air inlet 5.2 in the clean air conditioner room 5 is connected with return air inlet 4.1 pipelines of auxiliary cooling coil 4, and the 4 air-supply outlets 4.3 of auxiliary cooling coil are connected with air outlet 5.1 pipelines in clean air conditioner room 5, and formation return air circulates; The heat exchanging water pipe of auxiliary cooling coil 4 and precooling preheat coil 1 links to each other successively, constitutes the loop of first heat exchange water; Heat(ing) coil 3 links to each other with thermal source 7, constitutes the loop of second heat exchange water; Outdoor new wind communicates through the air outlet 5.1 pipeline gas circuits in precooling preheat coil 1, heat(ing) coil 3, auxiliary cooling coil 4, clean air conditioner room, constitutes new wind passage.
Fig. 3 be the utility model air conditioner structure and operational flow diagram two; Visible by figure; Be equipped with cooling coil 2 between said precooling preheat coil 1 and the heat(ing) coil 3, the heat exchanging water pipe of auxiliary cooling coil 4 and cooling coil 2, precooling preheat coil 1 links to each other successively, constitutes the loop of first heat exchange water; Outdoor new wind 6 is through the air outlet 5.1 in precooling preheat coil 1, cooling coil 2, heat(ing) coil 3, auxiliary cooling coil 4, clean air conditioner room 5, and pipeline connects gas circuit and communicates, and constitutes new wind passage.The flow in the loop of first heat exchange water is regulated control by valve 9.
Bigger at the outdoor new wind 6 of severe winter with the return air inlet 5.2 return air temperature difference in clean air conditioner room 5; Scheme shown in Figure 3 is as the improvement to scheme shown in Figure 2, and the cooling coil 2 of flowing through of the heat exchange water in the said auxiliary cooling coil 4 flows to precooling preheat coil 1 at last; Warm-up phase to outdoor new wind 6 divided for two steps carried out: outdoor new wind 6 is preliminary pre-heating temperature elevation in precooling preheat coil 1; Pre-heating temperature elevation again in the cooling coil 2 further heats up in heat(ing) coil 3 at last, the long-term stability operation that progressively heats up and help air-conditioning.With winter outdoor new wind 6 temperature be-1 ℃, air outlet 5.1 temperature in final clean air conditioner room 5 are 22 ℃ and are example, illustrate.Earlier by precooling preheat coil 1 pre-heating temperature elevation to 6 ℃; (winter does not need cooling and dehumidifying with energy-saving air conditioning through cooling coil 2 again; Said cooling coil 2 is actually assists cooling coil 4 heat exchange water heats to preheat usefulness in the loop that utilizes first heat exchange water); Temperature rises to 14 ℃, and heat(ing) coil 3 in the loop of second heat exchange water is warmed up to 22 ℃ again by thermal source 7 heat then.
After the return air that outdoor new wind 6 is drawn with clean air conditioner room 5 return air inlets 5.2 mixes, through the air-supply outlet 4.3 of auxiliary cooling coil 4, the air outlet 5.1 in clean air conditioner room 5, to 5 heating of clean air conditioner room.Whole flow process is only once heated up to heat(ing) coil 3 heat supplies by thermal source 7; Make full use of the heat of indoor return air in the auxiliary cooling coil 4; Make outdoor new wind 6 and preheat usefulness; Avoided outdoor new wind 6 earlier by 1 preheating of precooling preheat coil, cooling coil 2 cool-down dehumidifications, heat(ing) coil 3 heating again, complications repeat to heat the power consumption pattern, reach purpose of energy saving.
