Abstract

The invention relates to a natural energy cooler (cold box). Indoor refrigerators in the north in winter is kind of energy waste. The outdoor temperature is minor 10 DEG C to below minor 20 DEG C and the indoor temperature is about plus 20 DEG C, while the refrigerators try to rebuild a low-temperature environment indoors and give up the outdoor inexhaustible natural cold source. The invention is to use the cold weather as an alternative energy. For refrigeration, the invention provides a ''valve cooler (cold box)''. The cooler (5) is applicable to vegetable farmers and suppliers, and also in families. As shown in the ''drawings appended to the abstract'', the cooler can automatically keep the cooling temperature. The energy consumption of the cooler (cold box) belongs to refrigerating energy consumption but not control energy consumption, and uses an electrical contact temperature controller (13) and a reversible motor (14) to control two helix wheels (15) (16), so as to automatically mix the outdoor cold air with the hot air in a warm house (1), so the power consumption is low and the energy can be utmost saved.

Natural energy source freezer (case)

One, technical field:

Refrigeration (food fresh keeping)

Two, background technology:

Common refrigeration means are, in closed system, by what the compression of cold-producing medium and expansion process were obtained, also have compressed air refrigeration, absorption refrigeration and air-flow injection type refrigeration in addition.Fresh-keeping to vegetable and fruit, family realizes that by the refrigerating box in the refrigerator vegetables, fruit dealer still do not have cheap effective fresh-keeping means (freezer).

Three, summary of the invention:

The problem to be solved in the present invention is that the cheap fresh-keeping problem that solves northern China food in winter allows ice-cold the Nature become the low-temperature receiver of freezer (case) and household freezer.

The vegetables of northern China, the fruit producer and dealer, winter is fresh-keeping to be a very big difficult problem, and constant temperature is to be difficult for realizing, though also can realize, but cost is too high, usually people are placed on the not too low room of temperature with product, but because the fluctuation of temperature degree and lack effective temperature control means is difficult to guarantee refrigerated storage temperature, when room temperature is higher, rot easily, will freeze the bosom when room temperature is on the low side, cause very big waste.The present invention can be them a kind of effective constant temperature facility is provided.

The refrigerator that north of china in winter uses is the waste of the energy, outdoor is Celsius subzero more than ten to spend to more than 20 degree, and indoor is about 20 degree above freezing Celsius, yet prior art but remakes a low temperature subenvironment indoor, and abandon outdoor this inexhaustible natural cold source, this is very unfortunate.That designs here uses this natural cold source just, and in this case, the ice-cold world has also just become alternative energy.

The present invention not only will solve the fresh-keeping problem of product that vegetable grower's dish merchant, orchard worker really discuss, and also will solve the fresh-keeping problem of family's food.Fresh-keeping about the product that vegetable grower, dish merchant and orchard worker really discuss, what need is freezer; What family's food fresh keeping needed is refrigerating box.

Here ' natural energy source freezer (case) ' that provide also is divided into refrigerating box and household freezer, and be very simple for freezing problem, draws the outdoor cold source cartonning and can realize, introduces low-temperature receiver and realized that by conduit through walls cold air has directly entered household freezer.The refrigeration problem is the technical problem (distribution constant temperature) that the present invention solves emphatically.This refrigeration does not need the power consumption refrigeration, be that hot gas in outdoor cold air and the heating installation room is dissolved, make and form a temperature that is suitable for refrigerating in the freezer (case), such as 0-4 ℃, when temperature in the freezer (case) is low when reaching 0 ℃, give in the heating installation room of providing and delivering in the case than hot-air, when temperature is up to 4 ℃ in the refrigeration (case), to the outer cold air of Material Distribution Room in the case.Refrigerating box is not need not consume energy, and what need is controlled power consumption, rather than the power consumption of refrigeration property, and power consumption is faint, to greatest extent energy savings.
