Description
Technical field
The present invention relates to refrigeration technology field, especially a kind of ice-reserving heating double-purpose energy-saving air-conditioning device.
Background technology
In vast area cold in winter and hot in summer, heavy construction is now also generally using water cooled chiller refrigeration and boiler heating
Two sets of self-contained units, cooling in summer unit operation and heating installation leaves unused, heat supply in winter plant running and refrigeration unit is left unused, it is double
Weight cost, the comprehensive method of investment are very big.Water cooled chiller is energy-efficient refrigerating plant, is the first choice of building, because
The cooling load of building is big, and refrigeration unit configuration needs to meet summer maximum cooling load, and configuration power is big, and investment is big；And
And because there is no low-temperature heat source, it is impossible to be used in heating heating, winter are then completely idle.Net for air-source heat pump units can be with cooling in summer
Winter heating, but compared with water cooled chiller, cooling in summer ability is low, and Energy Efficiency Ratio is low, power consumption, operating cost is high, investment
Greatly, and because the cooling duty ratio heating demand of building is much larger, full load cooling uses air source heat pump cooling neither
Economy, investment are also bigger；Heating efficiency is low under net for air-source heat pump units winter low temperature operating mode, and design conditions must also meet to work as
The extreme cryogenic conditions in ground, crew qiting power are big, it is necessary to which constantly defrosting, overall efficiency is very low, and customer investment cost is very high.
Water resource heat pump is energy-efficient refrigerating ＆ heating apparatus, but needs a large amount of 10 DEG C -25 DEG C of warm water resource, in the winter time, the north
Regional more than 10 DEG C warm water resource wretched insufficiencies, at present the large-scale application of water resource heat pump limited by very strict.Water becomes
A large amount of 0 DEG C of latent heat of phase change can be released for ice, equivalent to the sensible heat of the water of 80 DEG C of temperature difference of homogenous quantities, also corresponds to 8 times 10 DEG C
