Abstract
The utility model discloses a kind of novel cold-storage and cool cold supply system again, comprise accumulation of energy pond, accumulation of energy pond connects refrigeration plant and terminal temperature difference by water pipe; Refrigeration plant comprises evaporimeter, condenser, gas-liquid separator, compressor, and described condenser is connected aftercooler with between gas-liquid separator, and aftercooler connects accumulation of energy pond by water pipe.Cold supply system of the present utility model by increasing aftercooler in original handpiece Water Chilling Units, refrigerant in aftercooler cools water, the temperature of refrigerant is more than 30 DEG C, after all becoming more than 10 DEG C after DEG C cold water of 5 in accumulation of energy pond freezes to user, aftercooler is connected to again by water pipe, the refrigerant of temperature more than 30 DEG C is cooled, such return water temperature can reach 20 DEG C, the temperature difference that utilizes in accumulation of energy pond is increased to 15 DEG C (5 DEG C/20 DEG C) from 5 DEG C (5 DEG C/10 DEG C), improves the energy storage density in accumulation of energy pond.
Description
Technical field
The utility model relates to a kind of cold supply system, particularly relates to a kind of cold supply system of water cold storage.
Background technology
Traditional cold-storage is mainly divided into ice conserve cold and water cold storage, and ice conserve cold feature is that cost is large compared with high storage density of cold, and the feature of water cold storage is that cost is low but storage density of cold is little.The accumulation of energy temperature difference of normal water cold-storage is 5-7 DEG C, and more operating mode is 5/10 DEG C, and namely after cold-storage at night, the temperature in pond is 5 DEG C, and after daytime released cold quantity, temperature is 10 DEG C.Its operation principle is as Fig. 1, and due to peak-trough electricity, evening, the electricity charge were lower, so water temperature is reduced to 5 DEG C by refrigerating device refrigeration by the water of feed pipe more than 10 DEG C by evening, and is stored in accumulation of energy pond; When daytime, the electricity charge are higher, and at this time in the middle of accumulation of energy pond, the cold water of 5 DEG C just can be freezed to user by plate type heat exchanger, and such daytime just can freeze with refrigeration plant less, saves the electricity charge on daytime.But after all becoming more than 10 DEG C after DEG C cold water of 5 in accumulation of energy pond freezes to user, the water in accumulation of energy pond just cannot carry out having freezed again, so the energy storage density how improving accumulation of energy pond further just seems very important.
Summary of the invention
The purpose of this utility model is to provide a kind of cold-storage with low cost and cools cold supply system again, can improve the energy storage density in accumulation of energy pond further.
The technical scheme that the utility model provides is:
Novel cold-storage cools a cold supply system again, comprises accumulation of energy pond, and accumulation of energy pond connects refrigeration plant and terminal temperature difference by water pipe; Refrigeration plant comprises evaporimeter, condenser, gas-liquid separator, compressor, and described condenser is connected aftercooler with between gas-liquid separator, and aftercooler connects accumulation of energy pond by water pipe.
Cold supply system of the present utility model by increasing aftercooler in original handpiece Water Chilling Units, refrigerant in aftercooler cools water, the temperature of refrigerant is more than 30 DEG C, after all becoming more than 10 DEG C after DEG C cold water of 5 in accumulation of energy pond freezes to user, aftercooler is connected to again by water pipe, the refrigerant of temperature more than 30 DEG C is cooled, such return water temperature can reach 20 DEG C, the temperature difference that utilizes in accumulation of energy pond is increased to 15 DEG C (5 DEG C/20 DEG C) from 5 DEG C (5 DEG C/10 DEG C), improves the energy storage density in accumulation of energy pond.
Accompanying drawing explanation
Fig. 1 is traditional cold-storage cold supply system schematic diagram.
Fig. 2 is the utility model cold-storage cold supply system schematic diagram.
Fig. 3 is the principle schematic that the utility model cold-storage cold supply system increases refrigerating capacity and efficiency.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
By Fig. 2, a kind of novel cold-storage cools cold supply system again, comprise accumulation of energy pond 1, accumulation of energy pond 1 connects refrigeration plant and terminal temperature difference by water pipe, refrigeration plant comprises evaporimeter 2, condenser 3, gas-liquid separator 4, compressor 5, described condenser 3 is connected aftercooler 6 with between gas-liquid separator 4, and aftercooler 6 connects accumulation of energy pond 1 by water pipe, is provided with refrigerant in aftercooler 6.
Under nominal situation, accumulation of energy pond 1 cold-storage temperature is 5 DEG C.Accumulation of energy pond 1 released cold quantity is divided into two stages: the situation that 1) water storage pool temperature is lower in earlier stage, the direct released cold quantity in accumulation of energy pond: the temperature difference is water outlet 5 DEG C, and backwater is 10 DEG C, and the cooling water in accumulation of energy pond is warmed up to 10 DEG C gradually.2) in the accumulation of energy later stage: by 10 DEG C of cooling waters being entered in the aftercooler of refrigeration plant (or heat pump) main frame, the temperature of refrigerant of more than 30 DEG C in aftercooler being reduced, by reducing the temperature of refrigerant, promoting the efficiency of main frame; Wherein, the supply water temperature in accumulation of energy pond is 10 DEG C, and return water temperature can reach 20 DEG C.
The operating mode in whole like this accumulation of energy pond is 5 DEG C-10 DEG C-20 DEG C, and the cold water namely in accumulation of energy pond becomes after 10 DEG C from normal 5 DEG C, becomes 20 DEG C again by aftercooler from 10 DEG C, increases the amplitude of cooling, adds amount of cooling water.Under the prerequisite not increasing pond cost, the cold storage capacity of the unit volume in pond increases greatly.
As Fig. 3, the aftercooler of cooling water first through arranging at condenser downstream, then enters condenser, just can realize cooling again of cold-producing medium.TK is the temperature of condenser, and T0 is the temperature of evaporimeter; 3-3 ' is exactly high pressure liquid refrigerant cooling procedure line again, and its temperature TSC reached is again cold temperature.Because high pressure liquid refrigerant cools again, when compressor power consumption is constant, unit mass chiller refrigeration ability increases q1(area: ab44 '), refrigerating capacity and refrigerating efficiency improve.
Described embodiment is preferred embodiment of the present utility model; but the utility model is not limited to above-mentioned embodiment; when not deviating from flesh and blood of the present utility model, any apparent improvement that those skilled in the art can make, replacement or modification all belong to protection domain of the present utility model.
