Description

Efficient calandria regenerator

The utility model relates to a kind of regenerator that cold-storage is transferred the lotus air-conditioning system, particularly a kind of efficient calandria regenerator of being used for.

In modern city, along with the continuous increase of various air-conditioning equipments and other industrial cooling device consumption, its power consumption is also increasing sharply, and its power consumption has reached 40～60% of city electricity consumption total amount, in coastal cities even higher.Therefore the difference between the electricity consumption round the clock of city is also increasing, and this has just caused electricity shortage in the daytime, and the poor circulation state of power wastage after midnight.In order to improve the supply of electric power present situation effectively, rationally utilize electric power, simultaneously also in order a stable electricity consumption to be provided, to use cool condition for air-conditioning and industrial cooling device, people have developed idle call " cold-storage is transferred lotus " technology, be about to night valley period power power and change low-temperature receiver into and stored, use for the electric power peak phase on daytime.

Technology of Cold Storage Air Conditions is the novel energy-conserving technology that external 80 years gas grows up mid-term, and its representational product has " cold-storage ball " and " pipe-disc type " two kinds of the U.S. of France.Now described with regard to above-mentioned two kinds of cold-storage technology:

1. cold-storage ball formula: filling can produce the medium (being generally water) of phase transformation in the ball, and a large amount of cold balls is placed in the cold-storage jar, feeds low temperature cold carrier (being generally salt solution) during cold-storage in jar, makes that medium freezes in the ball.Put when cold, feed the idle call cold carrier in the same side, make the ice-out in the ball.Its weak point is: a, cold-storage and put that cold carrier must be identical when cold, thereby make air-conditioning system have to use the expensive cold carrier of the stronger salt solution of corrosivity or other price, and can not use water commonly used to be cold carrier; If air-conditioning system makes water as cold carrier, this kind cold-storage mode then must increase a salt solution, clear water heat exchanger again, thereby has increased heat transfer temperature difference, has also increased air conditioning energy consumption; B, because the cold-storage ball mostly is plastic products, bigger thermal resistance is arranged when ice-melt and ice-reserving, add the principle that can not utilize the different natural layerings of water temperature well, its cold-storage efficient is reduced; C, cold-storage ball are closed structure, volumetric expansion during its interior water freezing, and a large amount of in addition Ice-storing balls accumulation compressings, spheroid is broken easily.

2. coiled: coil pipe is placed in the water tank, during cold-storage in pipe feeding cold carrier (being generally salt solution or refrigeration working medium), make outside tube pipe ice making, and with air pump bubbling in water tank.Its maximum shortcoming is to be difficult to guarantee evenly freeze and icing rate, damages coil pipe easily, and shipwreck is to flow freely during ice-melt.Performance is poorer when the air-conditioning underload.In addition, because of its structure is also not too perfect, cause the heat exchange area utilization rate low, ice-storage rate is low, invests relatively large.In a word, coiled has the trend that is replaced by cold ball formula.
