Problems solved by technology
[0003] At present, there have also been units that recover the heat released by the air conditioner during refrigeration to produce hot water. However, these unit devices cannot balance the temperature of hot water production and the amount of heat recovery. Some can provide high-temperature hot water but the heat It cannot be fully recovered, and the conventional heat (cold) recovery refrigeration unit can only recover 10% to 30% of the heat. Among them, the water-cooled heat recovery unit must be equipped with a condenser connected to the cooling tower, and the air-cooled heat recovery unit must be equipped with an air-cooled Condenser, although the existing part of the cold recovery heat pump water heater can realize 100% condensation heat utilization, but can only recycle part of the cooling capacity

This invention discloses a double effects compress type cold and hot water energy saving machine set which can fully recovers and uses the energy of cold and hot two sides to prepare hot water. The temperature of the hot water can be step-regulated. It includes compressor, condenser, expanding valve, evaporator and refrigerating circulating loop connected by refrigerating medium pipeline. It alsoincludes overheat zone high efficient heat exchanger, which medium side is connected into the refrigerating medium pipeline between the compressor outlet and the condenser. The waterway inlet and outlet of condenser connect to low temperature and middle temperature water inlet pipeline respectively. The waterway outlet of the condenser also connects to the water side inlet of overheat zone high efficient heat exchanger. The water side outlet of overheat zone high efficient heat exchanger connects to high temperature water outlet pipeline. This invention can be used in air conditioner energy saving field.
Description
technical field [0001] The invention relates to a double-effect compression cold and hot water energy-saving unit. Background technique [0002] Buildings such as hotels, hotels, restaurants, saunas, and swimming pools are generally equipped with air-conditioning units for cooling, and heating equipment for producing hot water for production, living, and sanitation. On the one hand, when the air conditioning unit is in normal cooling, the condensation heat is generally discharged through cooling water or air, and a large amount of heat energy is wasted; It can be seen that in some occasions that both cooling and hot water are needed, a lot of heat energy is wasted in the cooling process, while the process of generating hot water needs to consume additional fuel To generate heat, resulting in a double waste of energy and resources, which is not economical and pollutes the environment. People have deeply realized the necessity and urgency of saving energy and reducing consump...
