Description

Cooling and air-conditioning equipment

Technical field

The technical solution relates to cooling and air-conditioning equipment.

BACKGROUND OF THE INVENTION

For cooling and air conditioning, the principle of compressor cooling is currently used almost exclusively, which is very energy intensive even though it is technologically well-suited for different areas of application. It is the energy intensity of the compressor principle that places great demands on the sources of electric energy, which means not only high energy costs, but also a high load on the power transmission system, its outages, etc.

The object of the invention is to eliminate or at least minimize the disadvantages of the prior art.

The essence of the technical solution

The object of the invention is achieved by a cooling and air-conditioning device comprising an absorption cooling system to which at least one solar collector and at least one waste heat source and / or auxiliary electrical a heater connected to the electric power source, wherein the absorption cooling system comprises an evaporator and the space around the evaporator is bi-directionally connected to the cooled space.

The advantage of the technical solution is its complexity with the use of solar energy, waste and also other heat in combination with absorption cooling system and further in combination with energy storage, water heating, heating etc. 30 to 100%, so that the device can be operated even without the need for an external power source.

Advantageous embodiments of the invention are claimed.

Overview of the figure in the drawing

The technical solution is schematically shown in the drawing.

Examples of technical solution

The technical solution will be described on an exemplary embodiment in combination with a block diagram for higher christening.

The technical solution comprises at least one solar collector 7, which is connected by its heated medium outlet to the heated medium inlet to the absorption cooling system inlet 1. The solar collector 7 has a heated medium outlet temperature of about 100 ^° C to about ISO ° C and eg suitable cooling oil. In a non-illustrated embodiment, the solar collector 7 comprises a photovoltaic portion that produces electrical power to drive at least some 75 parts of the apparatus according to the present invention, eg a control system, a fan, a pump, etc.

The operating principle of the absorption cooling system as such is well known. and therefore only those parts that functionally associated with this invention will be described.

Further, an outlet of the heated medium from the waste heat source S is connected to the inlet of the absorption cooling system according to the illustrated embodiment. Further, an auxiliary electric heater (not shown) connected to the power supply 9 may be located at the inlet of the absorption cooling system.

CZ 19037 Cl

The absorption cooling system 1 comprises at its inlet a boil 3 which is essentially a heat exchanger between the heated medium from the solar collector 7 and / or the waste heat source 8 or from the auxiliary electric heater and the working charge of the absorption cooling system]. The absorber cooling system further comprises an evaporator 4 which removes heat from its surroundings.

that is, it cools its surroundings, and further comprises a capacitor 5 which radiates the heat removed by the evaporator 4.

The space of the absorption cooling system 1 around the outlet 4 is bidirectionally coupled to the cooled space 2, eg by a suitable duct or air duct system, the flow of which may be supported by a suitable fan, etc. ,

The condenser 5 is thermally coupled, e.g., via a liquid or air duct, etc., to the heat sink 6 of the condenser 5. The heat sink 6 is e.g. a domestic hot water heating device, heat pump ground collectors, a heat accumulator, etc.

The circulation of the individual media is ensured either by pumps or automatically determined by the principle of operation of the absorption cooling system U

The device operates such that the solar collector 7 heats the medium that is fed to the wand 3 of the absorption cooling system i. If a heat source 8 is used, the heated medium from the heat source 3 is also fed to the wand 3. If sufficient heat for heating the wax 3 is not produced by the solar collector 7 and a possible waste heat source 8, an auxiliary electric heater connected to the source 9 electricity. The absorption cooling system 1 utilizes the heat thus obtained to cool the condenser 4 and then to heat the condenser 5. The refrigerant from the condenser 4 cools the surrounding air, which is led to the cooled compartment 2, air. The heat from the condenser 5 is passed to a heat sink 6 by means of a suitable medium, where it is either consumed or stored for further use.

Industrial applicability

The technical solution can be used in various specific areas where cooling (refrigerators, freezers) or air conditioning (rooms, halls, production premises, office buildings, residential buildings, cars, boats, etc.) is required.
