Description
Technical field
The utility model relates to a kind of air conditioner energy-saving system, especially a kind ofly utilize underground water to freeze, be aided with again in case of necessity with being lower than normal cooling and warming power apparatus and freeze (or heating) to reach the system of energy-conservation purpose, specifically a kind of air conditioner energy-saving system based on groundwater refrigeration in the paddy electricity period at night.
Background technology
As everyone knows, continuous progress along with human society, energy resource consumption grows with each passing day, the surge of energy resource consumption causes the sharp increase of CO2 emissions, make the greenhouse gases effect obvious day by day, and then cause global temperature abnormality, sea level rise, all kinds of harsh weather are frequently taken place, and the loss that natural calamity caused can't be estimated.Therefore, energy-saving and emission-reduction have become the common recognition of the whole society, and various power-saving technologies are in the ascendant.
To consume a large amount of energy every year as the production office occupancy of all kinds of heavy constructions of urban development mark and all kinds of factories and miness enterprises and institutions and high-grade home dwelling and be used for refrigeration and heating winter in summer, though taked at present such as using the less cold-producing medium of depletion of the ozone layer, limiting a series of measures such as air-conditioner temperature in summer of machine-operated enterprises and institutions, however, it is still very surprising to be used for the power consumption of building air-conditioning every year.
At southern area, groundwater resources are very abundant, and class Area during Summer temperature is very high needs air conditioner refrigerating for this, and winter general temperature all above zero, do not need substantially to heat, the air-conditioning utilization rate is not high.And underground water is a kind of refrigerant medium that is in temperature constant state substantially, has huge value, is used for architecture refrigerating a kind of effective measures of energy-saving and emission-reduction especially if can will be starkly lower than the underground water of surface temperature.
Meanwhile; electric energy is a kind of energy that can't store; and the electric power transmission power determine according to daytime maximum power load calculate; and when night, most of consumer was in stopped status; electric energy has just slatterned in vain; therefore power department wishes that extremely people can be in the more electricity consumption at night; and on electricity price, formulated corresponding policy of rewards; (during paddy) electricity charge at night only are about 1/4th of (during the peak) electricity charge on daytime; therefore with night electric energy convert daytime required refrigeration to and (or heat; replenish as a kind of winter) energy replenishes groundwater refrigeration; to improve refrigeration greatly; save a large amount of energy, save operating cost.
According to the knowledge of the applicant, do not have still at present that a kind of to utilize underground water to freeze available with the energy-saving method for air conditioner and the system that realize energy-saving and emission-reduction, more do not have a kind of that the paddy electricity is available with the air-conditioning system that underground water organically combines.
The utility model content
The purpose of this utility model is the problem at the low and untapped utilization of underground water water temperature, designs a kind of air conditioner energy-saving system based on groundwater refrigeration that utilizes underground water to freeze.
The technical solution of the utility model is:
