example 1

[0072] The desorption cooler module in Figure 1 was tested and calculated to obtain an energy efficiency coefficient (COP) of 0.22 (refer to the system in US5522228 with a theoretical COP lower than 0.054). This calculation is made under the condition that the system in US5522228 is used as the basis for the following items.

[0073] Based on the system in US5522228, an assumption is made that each container 11 and 10 contains 100g of zeolite and carbon. The energy required to heat carbon from 0°C to 30°C is estimated to be about 2.1kJ. The energy required to heat the zeolite from 45°C to 70°C and from 70°C to 200°C is estimated to be approximately 1.75kJ and 9.1kJ, respectively. The energy taken away due to cooling from -40°C to -50°C is estimated to be about 0.7kJ. Ignoring the energy required for zeolite cooling from 190°C to 45°C, from 200°C to 190°C, and carbon from -50°C to 0°C (that is, due to the possibility of recycling energy from cooling material to heating material), C...

[0076] A demonstration unit was improved and tested for evaluation:

[0077] 1. The temperature of the regenerator is optimized;

[0078] 2. Cooling capacity, calculated in KJ;

[0079] 3. Energy efficiency coefficient (COP) or efficiency;

[0080] 4. The range of temperature drop reached in one cycle;

[0081] 5. Any impact of time on performance;

[0082] 6. The possibility of changing the heating and cooling rate or time to design an optimal time cycle for commercial systems.

[0083] The schematic diagram of the exemplary unit is depicted in FIGS. 3a and 3b, where the same reference numerals denote the same or similar parts as in FIGS. 1 and 2. The exemplary unit 40 includes one of the two modules A and B shown and described in FIG. 2.

[0084] Conduct research and optimization of one of the modules to collect relevant performance and design data, and therefore can be proportionally increased and decreased in the design of commercial modules.

Abstract

A method, apparatus and system for transferring heat is disclosed using a first gas adsorbent material, and a second gas adsorbent material that is relatively thermally isolated from but in continuous gas communication with the first material. In a first step the first material is heated so as to desorb a gas adsorbed onto the first material whereby the gas passes to and is adsorbed onto the second material. In a second step the first material is cooled in a manner so that the gas is desorbed from the second material and passes therefrom to be re-adsorbed onto the first adsorbent material. When the gas is desorbed from the second material, the second material is cooled thereby. In this way a hot gas stream can be used to cool another gas stream.

Description

Technical field [0001] The present invention relates to a method, device and system for heat transfer. The present invention is particularly used as a desorption cooler, which uses the heat of one fluid (gas or liquid) to cool another fluid, and is not limited to this article. In the description. Furthermore, the present invention can be applied conversely to enhance the cooling of hot fluids. In short, the present invention can be applied in a wide range of industries and related industries. Background technique [0002] Many industries emit mild heat treatment processes and exhaust gas to the atmosphere, thus wasting heat energy. This also leads to a warming of the atmosphere. Warm liquids, such as wastewater, are also released into the environment. People are eager to collect and use part of waste heat energy in industry or other fields. [0003] US5522228 discloses a device for generating cold through the adsorption and desorption of carbon dioxide. The device includes two co...
