Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically a dual-effect dual-source heat pump system. Background Technology

[0002] In beer production, the deoxygenated water used for dilution needs to be cooled to around 10°C, and the wort cooling process requires ice water cooling. Currently, both of these cooling processes rely on ammonia refrigeration units. In the beer bottling process, bottles need to be cleaned in a high-temperature environment, with the heat source being purchased or steam generated by the company's own boilers. The cost of steam varies depending on the temperature; the higher the temperature, the greater the investment cost. How to comprehensively utilize the heat from both the upstream beer production process and the downstream bottling process is a key research direction for energy conservation, emission reduction, and cost reduction for enterprises.

[0011] 1. The dual-effect dual-source heat pump system disclosed in this utility model relies on the heat and cold energy needs of beer production. It adopts high-temperature heat pump technology to absorb heat from deoxygenated water or room-temperature water that needs to be cooled, and transfers the heat to the bottle washing machine to perform high-temperature cleaning of the bottles.

[0019] The second plate heat exchanger 2 is provided with a second hot water outlet 21, a second hot water inlet 22, a second cold water inlet 23, and a second cold water outlet 24.

[0020] The first water circulation branch includes a first water source tank 4 and a first water source circulation pump 5 connected in series. The inlet pipe of the first water source circulation pump 5 is connected to the first water source tank 4, the outlet pipe of the first water source circulation pump 5 is connected to the first hot water inlet 11 on the first plate heat exchanger 1, and the inlet pipe of the first water source tank 4 is connected to the first hot water outlet 12 on the first plate heat exchanger 1.

[0021] The high-temperature water source heat pump 3 has a third water circulation branch on its evaporation side. The third water circulation branch includes a third water source circulation pump 6 connected in series and an evaporation side heat exchanger. The inlet pipe of the third water source circulation pump 6 is connected to the first cold water outlet 14 on the first plate heat exchanger 1. The drain pipe of the third water source circulation pump 6 is connected to the inlet of the evaporation side heat exchanger. The drain outlet of the evaporation side heat exchanger is connected to the first cold water inlet 13 on the first plate heat exchanger 1. The evaporation side heat exchanger exchanges heat with the evaporator of the high-temperature water source heat pump 3. The high-temperature water source heat pump 3 has a fourth water circulation branch on its condenser side. The fourth water circulation branch includes a fourth water source circulation pump 7 connected in series and a condenser-side heat exchanger. The inlet pipe of the fourth water source circulation pump 7 is connected to the second hot water outlet 21 on the second plate heat exchanger 2. The drain pipe of the fourth water source circulation pump 7 is connected to the inlet of the condenser-side heat exchanger. The drain outlet of the condenser-side heat exchanger is connected to the second hot water inlet 22 on the second plate heat exchanger 2. The condenser-side heat exchanger exchanges heat with the condenser of the high-temperature water source heat pump 3.

[0022] The second water circulation branch includes a second water source tank 8 and a second water source circulation pump 9 connected in series. The drain pipe of the second water source circulation pump 10 is connected to the second cold water inlet 23 on the second plate heat exchanger 2.

The inlet pipe of the second water source tank 8 is connected to the second cold water outlet 24 on the second plate heat exchanger 2.

[0023] The working principle of this utility model is as follows:

[0024] The first water source circulation pump 5 draws heat source water (deoxygenated water, tap water) to the first plate heat exchanger 1, where it exchanges heat and returns to its original location, thus creating a cycle.

[0025] The heat exchanger 1 enables the conversion of heat between the water in the first water circulation branch and the water in the third water circulation branch. At the same time, the isolation between the first plate heat exchanger 1 and the third water circulation branch prevents the heat source water and the high-temperature water source heat pump 3 from directly contacting each other, thus preventing impurities, acidic or alkaline substances in the heat source water from causing blockages or corrosion to the high-temperature water source heat pump 3. In addition, if the high-temperature water source heat pump 3 leaks refrigerant, it will not contaminate the heat source water.

[0026] The third water source circulation pump 6 outputs water to the water quality isolation plate heat exchanger 1, and after heat exchange, it returns to the evaporation side of the high-temperature water source heat pump 3.

[0027] The high-temperature water source heat pump 3 absorbs heat from the heat source water on the evaporation side and releases heat on the condensation side.

[0028] The fourth water source circulation pump 7 transfers the hot water from the condenser side to the second water circulation branch via the second plate heat exchanger 2, and then back to the heat pump, thus creating a cycle.

[0029] The heat generated by the high-temperature water source heat pump 3 is transferred to the user side through the second plate heat exchanger 2. At the same time, the heat source water and the high-temperature water source heat pump 3 are isolated by the second plate heat exchanger 2 and the fourth water circulation branch, so that the heat source water and the high-temperature water source heat pump 3 do not come into direct contact. This prevents impurities, acid and alkaline substances in the heat source water from causing blockage, corrosion and other damage to the high-temperature water source heat pump 3. In addition, if the high-temperature water source heat pump 3 leaks refrigerant, it will not contaminate the heat source water.

[0030] The second water source circulation pump 9 draws hot water from the usage side to the second plate heat exchanger 2, where it absorbs the heat from the hot water. The water then returns to its original location, and the cycle continues.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
