Abstract
A cold air case with cold air supply system mainly comprises cold air cases, lower-temperature air handlers and low-temperature return channels. One of the lower-temperature air handlers is connected with one of the cold air cases via one of the low-temperature return channels, and one of the cold air cases is connected with one of the lower-temperature air handlers via one of the low-temperature return channels, thereby forming a return circle. Because the utility model has no heat exchangers in the case, the structure of the case and the control are simple, and the manufacturing cost of the case can be reduced by 1/3 to 1/2. The active volume of the case is increased, the noise and the accidents are reduced, and the service life is extended. The forms and the kinds of the case are attractive and various because the utility model is not limited by the structure of the heat exchanger of original cases.
Description
Technical field: the utility model relates to a kind of refrigeration system, particularly a kind of cold wind cabinet and supply cold wind system thereof belong to the refrigeration professional domain.
Background technology: the refrigeration showcase that is used for the commercial exhibition sale of foodstuffs appears at the American-European countries of phase earlier 1940s the earliest, showcase at that time is that small enclosed is all-in-one-piece, be that cabinet has glass door, refrigeration unit is housed in the cabinet, be mainly used in the sale that the ice river in Henan Province is insulted, use in places such as hotels.Along with the developing rapidly of domestic and international supermarket, to the research of showcase also gradually deeply, and institution of higher learning and research organizations pay much have in the industry been caused since the nineties.Cabinet external environment temperature is also studied the cabinet Effect on Performance evaporimeter frosting in the cabinet.The frosting of refrigerant evaporator or refrigerating medium coil pipe is bigger to the cabinet performance impact in the showcase, and structure and the control to showcase simultaneously also has great influence, and is difficult to optimize and solves.Chen Tianji edits " commercial refrigerating " (Tianjin science tech publishing house; 2001.9) to the kind of showcase; structure; feature and designing and calculating etc. have been done detailed argumentation; the author is once to air themperature field in the showcase simultaneously; flow field and knot defrosting experimentize and test and reform research; the open-type display case air curtain is carried out CFD research (computer Simulation calculation air curtain fluidised form); in actual test, find showcase; the frosting of heat exchanger is very big to the influence of air curtain outlet air flow rate in the showcase of employing cold-producing medium or secondary refrigerant; with vertical open-type display case is example; because evaporimeter frosting; in 6 hours along with the increase of evaporimeter frost layer; the air outlet wind speed is reduced to 0.23m/s from 0.9m/s and is had a strong impact on the air curtain fluidised form; need 30 minutes and correspondingly adopt electric heating to shut down defrosting; 8 ℃ of in-cabinet temperature fluctuations of cabinet temperature rise this moment are bigger, and are difficult to avoid.The producer that has adopts the method for frequent defrosting, and the fluctuation of cabinet temperature is reduced, as the defrost in 20 minutes of every interval once, but the big poor reliability of energy consumption.
Summary of the invention: the present invention is directed to the deficiencies in the prior art, a kind of cold wind cabinet and supply cold wind system thereof are provided, mainly comprise: cold wind cabinet, low temperature wind processor and low temperature are sent the air channel back to, low temperature wind processor is sent the air channel back to by low temperature and is connected with the cold wind cabinet, the cold wind cabinet is sent the air channel back to by low temperature again and is connected with low temperature wind processor, constitutes a loop.According to the needs of handling air themperature, this machine can have the branch of high, medium and low temperature kind, the defrosting mode of heat exchanger selects choosing and will have more variation (as water defrosting etc.) in the machine, defrosing cycle also can design longlyer, and can in parallelly use this machine switching defrosting to make the wind-warm syndrome wind speed keep stable in 24 hours.This machine cooling system not only can keep the advantage of secondary refrigerant system (refrigerating medium system), can adopt that natural refrigerant (ammonia, carbon dioxide etc.) and filling quantity lack etc., and its performance is better than the secondary refrigerant system because no secondary conducts heat, requirement according to cold wind cabinet required air humiture, low temperature wind processor not only can be handled the air dehumidification of lowering the temperature, and also can be designed to cooling in case of necessity and add wet process.Low temperature wind processor should be transported to cabinet system by big as far as possible processing cold wind, the showcase of kind more than many can be connected in the quenching system of a low temperature wind processor, for the wet low-temperature cold wind that requires of different wind-warm syndrome, can also carry out secondary wind handles, satisfying the requirement of different showcase humitures, so this system is particularly useful for the supermarket cabinet system of trooping.The cold wind cabinet is mainly by cabinet, shelf with send the air channel back to and form, and can regulate the air port sending air channel inflow place setting back to, regulates required air quantity and the air curtain flow velocity of sending back in the cold wind cabinet.The design that this system sends the air channel back to is be connected can variation, but it is brief to be incubated and try one's best, so that further reduce air channel cost and minimizing air channel loss of refrigeration capacity.The cabinet system of trooping in supermarket is sent the air channel back to can be arranged on the interior part as cabinet of cabinet, according to the precedence of cold wind cabinet in cabinet system, determines to carry the size setting of air quantity or regulates the air channel flow area.Send the connection place that air channel and cabinet are sent air-return duct outside in the cabinet back to, can be located at top or the back or the bottom of cabinet, send the air channel back to and can close and put or split.Heat exchanger (refrigerant evaporator or refrigerating medium coil pipe) in the refrigeration wind cabinet is shifted out outside the cabinet, after the required cold wind of cooling is handled the state of regulation by low temperature wind processor in the cabinet, send in the cabinet, then flow back to low temperature wind processor by air-return duct by the air delivery duct.This system is because no heat exchanger in the cabinet, thereby no frosting and defrosing cycle fluctuate the in-cabinet temperature aperiodicity in the cabinet, and wind speed stablizes, and can cancel circulating fan in the cabinet.
The utility model is because the interior no heat exchanger of cabinet, make cabinet and control become simple, the cabinet production cost 1/3-1/2 that can descend, the cabinet dischargeable capacity increases, noise, fault reduce, life-span improves, owing to be not subjected to the restriction of former cabinet heat converter structure position, makes the form kind of cabinet will more become attractive in appearance and diversified simultaneously.
