技术领域technical field
本实用新型涉及一种回收中央空调机组冷凝热的水源热泵冷热水节能装置。The utility model relates to a water source heat pump cold and hot water energy-saving device for recovering condensation heat of a central air-conditioning unit.
背景技术Background technique
很多公共建筑普遍配置空调机组用于制冷，另外还要配置热源设备用于制取生产、生活及卫生用热水。空调机组在制冷时，冷凝热需通过冷却系统进行排放，大量的热能被白白浪费；而制取热水又需采用燃油、燃气锅炉或电热锅炉等传统的加热设备，因此多消耗大量能源。Many public buildings are generally equipped with air-conditioning units for cooling, and heat source equipment for producing hot water for production, living and sanitation. When the air conditioning unit is cooling, the condensation heat needs to be discharged through the cooling system, and a large amount of heat energy is wasted; while the hot water needs to use traditional heating equipment such as fuel oil, gas boiler or electric boiler, so a lot of energy is consumed.
为此中央空调余热回收技术应运而生。热回收的部位有两种，一种是在氟路上，另一种方式是在水路上。第一种方式是在压缩机排气端与冷凝器之间加装换热设备制热水。这种方式的优点是所制热水温度能达到45℃-55℃，基本可满足洗浴用热水的温度要求；缺点是会使排气压力上升，压缩机功率消耗增加，降低机组制冷能力，甚至引起机组过载跳闸，且制热水量有限。第二种方式是在冷却水水路上加装换热设备制取30℃-36℃热水。这种方式的优点是制热水量大；缺点是热水温度低，还需加热才能使用。For this reason, central air-conditioning waste heat recovery technology came into being. There are two places for heat recovery, one is on the fluorine road, and the other is on the water road. The first way is to install heat exchange equipment between the compressor discharge end and the condenser to make hot water. The advantage of this method is that the temperature of the hot water produced can reach 45°C-55°C, which can basically meet the temperature requirements of hot water for bathing; the disadvantage is that it will increase the exhaust pressure, increase the power consumption of the compressor, and reduce the cooling capacity of the unit. It may even cause the unit to trip due to overload, and the amount of heating water is limited. The second way is to install heat exchange equipment on the cooling water channel to produce hot water at 30°C-36°C. The advantage of this method is that the amount of hot water is large; the disadvantage is that the temperature of the hot water is low, and it needs to be heated before it can be used.
