Abstract
The invention discloses an ice storage temperature control method for an ice storage air conditioner. The ice storage temperature control method comprises the steps of placing a plurality of temperature sensing probes in an ice storage box at the suitable positions in the periphery inside the ice storage box and in the middle of the ice storage box; obtaining the measured temperature average value; setting the temperature to be lower than 0 DEG C such as minus 4 DEG C or minus 5 DEG C, and enabling the control accuracy to be +/-N DEG C (N is greater than or equal to 0); carrying out refrigeration continuously when the measured temperature average value does not reach the set temperature value and stopping refrigeration when the measured temperature average value reaches the set temperature value; carrying out refrigeration again when the measured temperature average value exceeds the set temperature value after temperature rise and repeating the steps. According to the method, a certain refrigerating capacity can be maintained, the requirement of the ice storage amount can be met, excessive refrigeration can be avoided, the cooling capacity can be maintained by setting the optimal refrigeration temperature on the basis of meeting the requirement of the ice storage amount, and the convenience and the economical efficiency are high. The ice storage temperature control method can be widely used for equipment such as lifesaving appliances.
Description
Technical field
The present invention relates to ice Thermal Storage Air-Conditioning Technology field, specifically a kind of ice-reserving temperature-controlled process of ice-storage air-conditioning.
Background technology
Ice-storage air-conditioning is now widely used in the equipment such as lifesaving appliance, because lifesaving appliance requires that installing space, ice storage amount and ice-reserving temperature and common ice cold accumulation air-conditioner have very large difference, so can not by common ice the design of cool storage air-conditioning system.Survival capsule air-conditioning only uses when there is disaster, as long as maintain low temperature ice-reserving at ordinary times.Because installing space is limited, and ice storage amount only demand fulfillment personnel to sustain life demand, if ice-reserving temperature is too high, ice storage amount does not reach requirement, and is such as mixture of ice and water in ice-storage box during zero degree, cold storage capacity is not by far up to the mark; If ice-reserving temperature is too low, though ice storage amount meets the demands, cause cold excessive, long low temperature ice-reserving excessively, Energy Efficiency Ratio is very low, and waste resource, brings heavy financial burden to client.A kind ofly the temperature-controlled process that ice storage amount can not cause again excessively refrigeration can be met so need to find.
Summary of the invention
The object of this invention is to provide a kind of ice-reserving temperature-controlled process of ice-storage air-conditioning, certain refrigerating capacity can be maintained, ice storage amount requirement can be met and can not cause excessive refrigeration again, on the basis meeting ice storage amount, cold is maintained with the setting cryogenic temperature of the best, convenient economical.
Technical scheme of the present invention is as follows:
An ice-reserving temperature-controlled process for ice-storage air-conditioning, is characterized in that: specifically comprise the following steps:
(1), in the ice-storage box of ice-storage air-conditioning place some temperature-sensing probes, some temperature-sensing probes lay respectively at the surrounding of ice-storage box inside and middle suitable position;
(2), some temperature-sensing probes record the surrounding of ice-storage box inside processed and the temperature in centre position, and the temperature data recorded are reached the controller of ice-storage air-conditioning, through calculating, obtaining temperature averages, and showing on external display;
(3) if when ice-reserving average temperature value is 0 DEG C ~-3 DEG C, be mixture of ice and water in ice-storage box; If ice-reserving average temperature value be-4 DEG C or-5 DEG C time, can ensure in ice-storage box completely icing, thus setting temperature value adopt-4 DEG C or-5 DEG C, control accuracy is ± N DEG C (N >=0);
(4), when the temperature averages recorded does not reach the temperature value of setting, the controller of ice-storage air-conditioning continues to open air conditioner refrigerating control program and freezes, and continues refrigeration; When the temperature averages recorded reaches the temperature value of setting, the controller of ice-storage air-conditioning stops air conditioner refrigerating control program, stops refrigeration;
(5), when ice-storage box is inside and outside constantly pass through heat exchange, when making the temperature averages recorded constantly go up and exceed the temperature value of setting, the controller of ice-storage air-conditioning reopens air conditioner refrigerating control program and freezes, and so goes round and begins again.
The ice-reserving temperature-controlled process of described ice-storage air-conditioning, is characterized in that: described some temperature-sensing probes are specifically arranged in the surrounding of ice-storage box ice making coil pipe and middle suitable position respectively.
Beneficial effect of the present invention:
1, the present invention is contained in whole refrigeration control program, realization simple and easy to control.
2, the present invention is on the basis meeting ice storage amount requirement, maintains cold, can not cause excessive refrigeration with the setting cryogenic temperature of the best.
3, the present invention is under the prerequisite ensureing overall ice-reserving, decreases the usage quantity of temperature-sensing probe.
4, the present invention is economical and practical, decreases cost.
