Abstract

The utility model provides an energy-saving type refrigeration house, comprising an outer wall body, a benzene board thermal insulating layer, an inner wall body, an ice house, a refrigeration house, a circulating blower, an ice storage groove, a liquid ammonia pipe, a separation wall body, an air duct, a front door of the ice house, a rear door of the ice house and a refrigeration house door; in the utility model, natural resource which has low temperature outside room in winter is utilized comprehensively, cold energy is stored in an ice way; low temperature of the refrigeration house is led in the inside of the refrigeration house by the blower in an air circulating convection current way, so as to achieve the low-temperature refreshing purpose.

Description

Energy-saving freezer

(1) technical field

The utility model relates to a kind of power saving refrigerator, utilizes blower fan that air between icebox and the freezer is flowed specifically and makes the power saving refrigerator of freezer refrigerating.

(2) background technology

Freezer is one of best way that stores at present product easily influenced by ambient temperature, and the most mechanical freezers of China mainly are to adopt the steam compression type refrigeration mode to regulate the storehouse temperature at present.So-called mechanical freezer is said the freezer that freezes with mechanical means exactly simply.Refrigeration principle can be sketched and be: utilize the evaporation of the lower liquid refrigerant of vapourizing temperature, absorb the heat in the storage environment, thereby the storehouse temperature is descended.Cold-producing medium after will vaporizing by compressor sucks back and pressurizes, and cold-producing medium makes the heat transferred cooling medium that absorbs self temperature be minimized, be condensed into liquid, and then evaporates heat absorption in condenser, and so circulation can realize continuous cooling.Compressor plays action of the heart in whole refrigeration system, provide the process of energy compensating.Condenser and evaporimeter are two heat exchangers, and the former makes the gas heat release of high-pressure refrigerant, and is converted into liquid; The latter makes the liquid heat absorption of low pressure refrigerant, and is converted into gas.Cold-producing medium becomes the delivery vehicle of heat energy in the process of moving in circles.

It is reported that abroad, freezer power consumption average level is greatly about every cubic metre 50 kilowatt hour in every year, best reach annual every cubic metre 16 kilowatt hour.At home, the whole nation of this index refrigeration enterprise average level is annual every cubic metre 106 kilowatt hour, more than the twice that aspect the energy consumption is developed country.The utility model is at current domestic natural environment, especially be with in northeast one, winter, outdoor temperature can reach below subzero 20 degree, manufacturing and stored ice are very easy, by blower fan the cold air of ice cube surface or icebox inside is imported cool house internal in the circulative convection mode then, freezer is kept about 2-4 ℃ throughout the year.

(3) summary of the invention

The purpose of this utility model is to provide a kind of energy-saving freezer, is a kind of energy savings, the preservation by low temperature facility of protection environment.

In order to overcome the high defective of most mechanical freezer power consumptions, the present invention fully utilizes the natural resources of outdoor low temperature in winter, with the form storage of cold source of ice, in wind circulative convection mode the low temperature of icebox is imported cool house internal by blower fan, and reach the preservation by low temperature purpose.

The purpose of this utility model is achieved in that it comprises outer body of wall, polystyrene board heat-insulatation layer, interior body of wall, icebox, freezer, circulating fan, ice machine bin, liquid ammonia tube, isolation body of wall, air channel, icebox Qianmen, icebox back door, cold-storage door.

The utility model can also comprise some features like this:

1, outer body of wall, interior body of wall, to isolate wall body brick thick be 150mm, heat-insulation layer benzene plate thickness is 400mm.

2, icebox is provided with former and later two doors.

3, be provided with ice machine bin in the icebox, liquid ammonia tube is installed in the ice machine bin.

The beneficial effects of the utility model are, when winter, outdoor temperature was below 0 ℃, open icebox front and back door, close icebox front and back door behind the water freezing in the ice machine bin and can start the blower fan use, primer fluid ammonia machine when having only outdoor temperature more than 0 ℃ makes the water freezing in the ice machine bin.This invention has made full use of outdoor low temperature resource, with the form storage of cold of ice, the cold store energy saving of foundation, environmental protection.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model.

(5) specific embodiment

For example the utility model is done description in more detail below in conjunction with accompanying drawing:

The composition of energy-saving freezer comprises that body of wall, 4 is isolated body of wall, 5 iceboxs, 6 freezers, 7 blower fans, 8 air channels, 9 ice machine bins, 10 liquid ammonia tubes, 11 icebox Qianmens, 12 icebox back doors, 13 cold-storage doors in 1 outer body of wall, 2 heat-insulation layers, 3.When winter, outdoor temperature was below 0 ℃, open icebox front and back door, close icebox front and back door behind the water freezing in the ice machine bin and can start the blower fan use, outdoor temperature is the primer fluid ammonia machine more than 0 ℃ the time, make the water freezing in the ice machine bin, close the liquefied ammonia refrigeration machine then, open blower fan and can use.
