Evi high temperature heat pump

• The high-temperature heat pump collects the heat in the low- and medium-temperature waste water and waste gas discharged and wasted by industrial enterprises through the high-temperature heat energy heat pump, and converts it into water or high-temperature steam of ≤150 °C for industrial process or heating use, which can directly replace the traditional Coal-fired boilers are the best choice for industrial energy saving, consumption reduction and efficiency improvement.

 

Working principle

• 2. Condensation process: The high temperature and high pressure refrigerant gas from the compressor flows through the condenser, uses wind or water to continuously release heat to the outside, and condenses into medium temperature and high pressure refrigerant liquid. During liquefaction, the temperature of the refrigerant decreases but the pressure remains unchanged, which is called an isobaric process in thermodynamics.
• 3. Throttling process: The medium-temperature and high-pressure refrigerant liquid from the condenser is throttled by the throttling device and becomes a low-temperature and low-pressure refrigerant liquid. In thermodynamics, it is called an isenthalpic process.
• 4. Evaporation process: The low-temperature and low-pressure refrigerant liquid from the throttling device flows through the evaporator, absorbs heat into the room with wind or water continuously, and evaporates into a low-temperature and low-pressure refrigerant gas. The absorbed heat becomes the latent heat of the refrigerant, and although the temperature rise is not large, the internal energy increases a lot. Because the pressure does not change much, it is called an isobaric process in thermodynamics.

 

Skills requirement

• Compared with the air source heat pump technology whose output temperature is below 60°C, the high-temperature heat pump can provide heating temperature above 60°C without changing the operating environment of the equipment, and maintain high operating efficiency and stable operating state. Generally, it is necessary to solve the problem. The following key technical issues.
• 1. Compressor selection: The commonly used compressor types for heat pump equipment are mainly screw compressors, hermetic scroll compressors and semi-hermetic piston compressors. The equipment generally uses a hermetic scroll compressor.
• 2. Selection of working medium: In order to ensure that the high temperature heat pump equipment is used under a stable allowable working pressure, a special refrigerant is used as the working medium, which has high heat exchange efficiency and no pollution to the environment and no damage to the ozone layer.
• 3. Optimization of fluorine circuit system control: to ensure the long-term high-temperature stable operation and service life of the entire unit, and automatically adjust the operating state and adjustment of the high-temperature air heat pump equipment according to the ambient temperature and evaporation temperature.

Four advantages

• 1. Energy saving is conducive to the comprehensive utilization of energy. The high temperature air energy heat pump absorbs the low temperature heat energy in the air and converts it into high temperature heat energy after being compressed by the compressor. The energy saving effect is quite significant.
• 2. Conducive to environmental protection
• 3. Combination of cold and heat, high equipment application rate, saving investment
• 4. Because it is electric, the control is more convenient. Compared with electric boilers, it can save more than 50% of power consumption and reduce the trouble of frequent replacement of electric heating tubes; compared with traditional coal-fired boilers and oil-fired boilers, it is pollution-free, emission-free, and safe, eliminating the need for annual routine security checks. Save professional boiler workers, automatic temperature control, greatly reduce operating costs by more than 50%.
