Refrigerating plant with refrigeration, heat exchange, cold-storage complex function
Technical field
The utility model relates to a kind of refrigerating plant with refrigeration, heat exchange, cold-storage complex function.
Background technology
Along with the development of society, many occasions need be carried out cooling throughout the year, and the air conditioning energy consumption of at present simple employing compression refrigeration mode cooling is bigger.In spring, autumn, winter, usually environment point environment temperature can be lower than the temperature with cold spot, owing to possessing the condition that the air, water and the soil that utilize in the natural environment cool off, often can adopt heat exchange method to replace the compression refrigeration mode in this case.
And when summer, because electric load differs greatly round the clock, Utilities Electric Co. can adopt the mode of peak, paddy, charging when dividing equally to collect the electricity charge usually.If air-conditioning is worked when the electricity charge at night paddy, the low temperature solid-state form of energy with energy-accumulation material stored, when daytime, the electricity charge were in peak value, close the bigger compressor of power consumption, only open less fluid drive apparatus of power consumption and blower fan, the energy-accumulation material that will accumulate night melts, and utilizes energy-accumulation material to come cooling by solid-state liquefy release latent heat and sensible heat, can play the effect of peak load shifting, save electricity charge spending.
The product that has hot-swap feature in the market normally is used to the aeration device of taking a breath, the air of discharging carries out sensible heat or full heat exchange when flowing through heat exchange core body and between the fresh air of suction, can only reclaim the energy of discharging in the gas, can not play regulating and controlling effect to temperature with cold spot, and it is bigger to have the on-site installation work amount, can't the partial installation shortcoming.
Existing cold accumulation system mainly adopts large-scale ice-reserving bucket, groove on the market, the center system of forming by refrigerator and pump, heat exchanger and other component, the central air-conditioning that suitable refrigeration requirement is bigger, on-the-spot connecting line and the complicated automaton of installation of needing, can not accomplish plug and play, also can't be used for the less occasion of refrigeration requirement.
