Hot water supply is the most basic service of the hospital just ike hotels and guesthouses, meanwhile hospital hot water does not have the so-called peak period, patients or doctors use hot water all the time. Therefore, the hospital must be able to ensure that there is stable hot water 24 hours a year. At present, hospital hot water generally uses air source heat pump. Low ambient temperature air source heat pump can help hospitals in cold areas maintain constant temperature hot water supply all year round, and achieve the goal of emission reduction and environmental protection.
The upgraded R410A environment-friendly refrigerant is adopted, which has higher density in low-temperature environment and significantly improves the heating capacity per unit volume. At – 7 ℃ – 0 ℃, the heating efficiency is more than 50% higher than that of ordinary heat pump, and the heat pump can keep normal operation at – 25 °.

Comprehensive advantages of low temperature heat pump:
1. Stable and reliable
The air source heat pump heating system equipped with EVI jet enthalpy increasing technology, solves the problems of low-temperature heating attenuation and too high compressor exhaust temperature. Even in the severe cold area of – 35 ℃, the low-temperature air energy heat pump system still operates reliably and has strong heating.
2. Superior economic performance
Although the differences in maintenance structure between the South and the north, outdoor temperature and relative humidity, residents’ habits and defrosting control have a great impact on the economy of unit operation, air source heat pump is still more economical and energy-saving than gas wall mounted boiler and electric heating, saving 15% – 70% of operation cost, whether replacing coal-fired boiler central heating or independent user heating, They are the preferred schemes for energy conservation and environmental protection.
3. Comfortable use experience
In the application of air energy heat pump heating in different climate zones, the temperature level in the user’s room is well maintained. With good indoor system layout and design, the temperature gradient and fluctuation meet the requirements of ergonomics for comfort; In addition, the thermal comfort of floor radiant heating is better than that of radiator. It can get a comfortable and uniform thermal environment with low-temperature hot water. It is a good choice for a new type of comfortable heating mode.
