Cold-storage (heat) formula small central air conditioning and solar water heating system characteristics
1, the comparison of several air-conditioning forms
2, the comparison of several water heater forms
By above comparison, we draw cold-storage (heat) formula small central air conditioning and solar water heating system has following characteristics:
1, saves initial cost.Present dwelling house (particularly villa) area is generally all larger, although rooms all when installing an air-conditioner generally all install an air-conditioner, but the real room of air-conditioning that often uses is also few, and some room use (such as dining room and bedroom) of also can staggering, if so by air-conditioning form now commonly used, all be to configure at full capacity the air-conditioning unit according to the air-conditioning area, initial cost is just very large like this, and the domestic air conditioning to more often not using, just more easily go wrong, if common residential central air-, the main frame cold selects large, just power consumption during operation, if but the room that air-conditioning seldom uses do not install an air-conditioner, although initial cost can reduce, in a single day this room will not have again handy with air-conditioning.Native system has just solved this contradiction well.
2, save operating cost.This system just can save for usual operating cost by the refrigerated medium heat of the load apolegamy air-conditioner host that often uses air-conditioned room very much, when meeting all rooms and all will use the situation of air-conditioning, then relies on the cold-storage of attemperater to solve.
3, can utilize honeybee paddy electricity price, farthest cost saving.After having carried out time-of-use tariffs, we just can take full advantage of electricity price when minimum, carry out the operation of cold-storage heat, then when electricity price is high, utilize hold cold and hot, for the room air-conditioning.
4, can take full advantage of one day in the middle of best running environment, carry out cold-storage heat operation.Such as summer (winter at noon the warmest time) when the time after midnight, weather was pleasantly cool, carry out cold-storage (heat) operation, with regard to improving the Energy Efficiency Ratio of refrigeration (heat), reach energy-conservation purpose like this.
5, utilize solar energy that health hot water is provided, this is the most energy-conservation, in order to solve the problem of reliability in its in winter, we are the switching of air-cooled heat pump water chiller-heater units by magnetic valve, auxiliary heating as solar water heating system, because the load of air-conditioning generally is greater than the required load of one family's health hot water, so health hot water has just had reliable assurance.
6, air-conditioning system and solar water heating system are organically combined, not only air-conditioning system can be assisted sanitary hot water system, but simultaneously also auxiliary air conditioner heating of solar energy sanitary hot water system, thus energy savings farthest.Need only the position suitable that solar water heating system collecting plate 6 is installed for the solar energy sanitary hot water system, solar water heating system circulating pump 7 also shouldn't.
7, for this system, it is exactly to have suitable position to place the hot attemperater 2 of air conditioner cold accumulation that a shortcoming is arranged, if the air conditioner load that uses the once in a while time very large, that use is very long again, the volume of the attemperater of cold-storage (heat) usefulness is just very large so, and this just more increases the requirement to this water tank putting position; Volume for the attemperater that dwindles cold-storage (heat) usefulness, increase the amount of cold-storage (heat), also can in water tank, add the large material of cold-storage (heat) amount, for example under air-conditioning and heating temperature, the material that can undergo phase transition, it is divided in the airtight one by one bead, bead is put into water, thereby reach the purpose that increases cold-storage (heat) amount.
This product optimum is installed in the apartment of villa independently or building top layer.
