Abstract
The utility model relates to a dehumidification fresh air unit with dual coil pipes. A filter screen, a high-temperature surface cooler, a low-temperature surface cooler and a fan are arranged in sequence in a fresh air unit shell along the fresh air inlet direction, wherein the high-temperature surface cooler and the low-temperature surface cooler are connected with a high-temperature cooling medium system (14-20 DEG C) and a low-temperature cooling medium system (5-12 DEG C); and the bottom of the low-temperature surface cooler is provided with a water receiving tray. In the utility model, a sensible heat load which accounts for 50-70 percent of the overall load ratio is treated by using a high-temperature cold medium with the temperature of between 14 DEG C and 20 DEG C, so that waste of energy source grade caused by the adoption of a method for treating sensible heat and latent heat with a single low-temperature cold source in an combined way in the conventional fresh air unit is avoided, the running efficiency of a refrigerating host machine is improved, and the aim of saving energy of the system is fulfilled; moreover, by treating sensible heat and latent heat loads of fresh air respectively, the problem caused by large change of the heat humidity ratio of outdoor fresh air is solved; and when the sensible heat load is high, the heat exchanging cooling effect is improved by appropriately lowering the temperature of the high-temperature cooling medium, and the dehumidifying effect of the fresh air can be ensured fully.
Description
Technical field
The utility model belongs to apparatus of air conditioning technical field, relates to a kind of new blower fan group of cooling off or dehumidifying of being used in the air conditioner fresh air system, and product can be used on central air-conditioning and humiture independence control air conditioner system.
Background technology
In the apparatus of air conditioning, the fresh air conditioner load comprises sensible heat and two kinds of loads of latent heat, and wherein sensible heat load proportion in total load is about 50～70%.The new blower fan group of central air conditioner system use at present adopts the single coil design usually, and single coil feeds single low temperature cold source (5～12 ℃ of chilled waters) will bear new wind sensible heat and latent heat load simultaneously, promptly will finish two kinds of functions of cooling and dehumidifying simultaneously.Because changing according to outdoor environment, the ratio of latent heat and sensible heat load changes, its heat moisture ratio excursion is bigger, and the mode that the new blower fan group of tradition adopts single low temperature cold source to handle sensible heat and the latent heat air heat moisture ratio that can not conform preferably on the one hand changes, adopt low temperature cold source to handle the waste that new wind sensible heat load also causes energy grade on the other hand, cause the COP (coefficient of performance) of refrigeration unit to reduce.
The utility model content
The utility model purpose is the problem that existing new blower fan group exists is solved, and a kind of double plate pipe that utilizes high temperature low-temperature receiver and low temperature cold source that new wind sensible heat and latent heat load are handled respectively that adopts the design of double plate pipe new blower fan group that dehumidifies is provided.
The technical solution that adopts is so for achieving the above object: the double plate pipe that the is provided new blower fan group that dehumidifies has the new Blower Housing of a two ends band fresh wind port and air outlet, in new Blower Housing, be disposed with screen pack by new wind air intake direction, the pyrometric scale cooler, cryometer cooler and blower fan, new wind enters new Blower Housing from fresh wind port, pass through screen pack afterwards successively, the pyrometric scale cooler, the cryometer cooler, blow out through air outlet by blower fan again, said pyrometric scale cooler and cryometer cooler are connected with 5～12 ℃ low temperature refrigerant system with 14～20 ℃ high temperature refrigerant system respectively, are provided with drip tray in cryometer cooler bottom.In the said structure, the pyrometric scale cooler inserts the eliminating that high temperature refrigerant can be used for new wind sensible heat, and the new wind that the cryometer cooler inserts after the low temperature refrigerant can be handled the pyrometric scale cooler carries out the secondary cooling condensation, is mainly used in and gets rid of new wind latent heat.
Compared with prior art, the utility model is owing to utilize the sensible heat load of high temperature refrigerant processing proportion 50～70% in total load of 14～20 ℃, the energy grade waste of having avoided traditional new blower fan group to adopt single low temperature cold source Combined Treatment sensible heat and latent heat method to be caused, because raising, refrigerant temperature improved the operational efficiency of refrigeration host computer, thus the energy-conservation purpose of feasible system; On the other hand, handling respectively of new wind sensible heat and latent heat load helped solving outdoor new wind heat moisture ratio change the problem of being brought greatly, when sensible heat load is big, can suitably reduce the high temperature refrigerant temperature, increase the heat exchange cooling effect, so just can fully guarantee the fresh air dehumidification effect, having overcome traditional new blower fan group refrigerant supply water temperature immobilizes, when sensible heat load is big, increase, thereby cause unit dehumidifying part ability to reduce to cause the defective of humidity precision imbalance relatively owing to the aggregate demand load changes sensible heat to be got rid of loaded.
