Description

A kind of silent air-conditioning system

Technical field

The invention belongs to the air-conditioning equipment field, relate to a kind of air-conditioning system, relate in particular to a kind of silent air-conditioning system.

Background technology

At present, existing enterprise or family's central air-conditioning end all adopt air conditioner with blower and coiled tube to indoor refrigeration or heating operation, fan coil mainly is made of snakelike copper pipe overcoat aluminium finned air table cold heat exchanger and blower fan, utilize blower fan to force room air to flow through air table cold heat exchanger, by the chilled water that circulates in fin and snakelike copper pipe outer wall and the copper pipe realize to the room air refrigeration or with copper pipe in the heating hot water that circulates add the purpose that hot-air reaches heating.But the blower fan running must produce mechanical vibration noise, and when surface cooler was crossed in wind, air-flow and copper pipe and fin produced friction noise, still do not have technology at present and can eliminate this noise.

Though each producer competitively adopts the way that reduces rotation speed of fan to reduce above-mentioned noise, all can not fall lowly excessively, otherwise will influence the exchange capability of heat of fan coil, causes refrigeration air-conditioner and heating deleterious.Therefore, though can reduce some noises by reducing rotation speed of fan at present, noise can't be eradicated, reach the noise-sensitive crowd for nighttime sleep is bad, the noise that fan coil produces is a pain in the neck, would rather cut off air-conditioning and also be unwilling to allow noise jamming have a rest.And the air conditioner with blower and coiled tube operation time is being opened in sleep, uncomfortable air conditioner diseases such as sneezing easily, have a running nose, nasal obstruction, four limbs and waist are ached, this is because people do not need so big refrigerating capacity when sleep, therefore, even people are transferred to the deep low gear position with the rotation speed of fan of fan coil before sleep, also of no avail, thus certain worry caused to people.

Utilize ground coil pipe heating to progress into the central air-conditioning heating system in recent years, ground coil pipe heating is not provided with blower fan structure, has eliminated the noise that is produced by blower fan fully.But the ground coil pipe can only the winter heating heat supply, and this is because its water temperature of cooling chilled water is about 7 ℃, and the ground coil pipe feeds after 7 ℃ of chilled waters, will cause the floor to produce dew, therefore, should not use summer ground coil pipe circulation chilled water to carry out refrigerating operaton.

In sum, summer, refrigeration can only be used the air conditioner with blower and coiled tube refrigerating operaton at present, did not still have other way and substituted the operation of fan coil refrigeration air-conditioner, continued from the rotating speed aspect Research Significance of blower fan not quite again, did not also have bigger results.

In actual the use, embodiment 1,2,4 and 5 can constitute high-capacity air conditioning system by the multiple groups of loop parallel connection, utilizes the cheap electricity charge accumulation of energy operation of paddy electricity, and not only energy-saving and emission-reduction are remarkable, and obtain extremely low operating cost.

Adopt this silent air-conditioning system, when daytime or need fast-refrigerating or during heating operation, open air conditioner with blower and coiled tube, because fan coil is by the heat exchange of blower fan forced air, so the heat exchange amount is bigger, refrigeration or heating speed are fast, satisfy the demand of people to indoor fast cooling or intensification.Do not need higher at ordinary times or during low indoor temperature, close the blower fan of fan coil,, not only obtain cosy indoor temperature, can also enjoy quiet indoor environment by radiator independent cooling or heating operation.

When people in bed, only close the fan operation of fan coil this moment, the hot and cold water in the fan coil still circulates, with room air heat transfer free convection, though the heat exchange effect greatly reduces, the radiator in the room still circulating cold water or hot water are with natural convection air heat exchange in the room.Although radiator is not so good as fan coil in the good refrigeration effect in summer, but it is human when sleep, particularly summer to the demand of refrigerating capacity than sleep state is not much lower, in order to satisfy the requirement of people to little refrigerating capacity, just in time close the blower fan of air conditioner with blower and coiled tube, change by the radiator heat convection, add fan coil the heat transfer free convection amount behind the blower fan of closing needs to refrigerating capacity when just satisfying human sleep, thereby avoided by the excessive air conditioner disease of the many discomforts of health brought of refrigeration of air-conditioner.

Owing to dispose drip tray and condensed water tapping pipe below the radiator, the condensed water that the chilled water that circulated in the radiator when summer, refrigeration air-conditioner moved produces by radiator and air heat exchange, splash in the drip tray, converge the back and drain into the sewer floor drain by the drip tray tapping pipe of flowing through, flow among the sewer, the condensed water when having avoided refrigeration is to the influence of indoor environment.

The present invention is described by embodiment, and those skilled in the art know, under the situation that does not break away from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under guidance of the present invention, can make amendment to these features and embodiment does not break away from the spirit and scope of the present invention to adapt to concrete situation and material.Therefore, the present invention is not subjected to the restriction of specific embodiment disclosed herein, and all interior embodiment of claim that fall into the application belong to the scope of protection of the invention.
