Variable-frequency air source capillary radiation heat pump unit and controlling method thereof

Abstract

The invention discloses a variable-frequency air source capillary radiation heat pump unit and a controlling method thereof. The variable-frequency high-efficient heat pump unit is customized for application of a capillary radiation air conditioner system, and is specially and optimally designed aiming at the problems that the capillary radiation air conditioner system requires cold water with high water outlet temperature during refrigerating and hot water with low temperature during heating, and the energy efficiency ratio of the unit is greatly improved; optimized design according to application water temperature characteristics of capillary radiation is adopted, so that the full load energy efficiency ratio of the unit is greatly enhanced; a direct current inverter compressor and a direct current inverter fan are adopted, so that comprehensive partial load performance coefficient of the unit is greatly enhanced; and a controller developed by aiming at capillary radiation application can better meet the needs of capillary radiation application, and a variety of hidden dangers and operational inconvenience caused by former common cold water heat pump controller are completely changed.

Description

technical field [0001] The invention belongs to the technical field of capillary radiation air conditioning, in particular to a frequency conversion air source capillary radiation heat pump unit and a control method thereof. Background technique [0002] Capillary radiation air conditioning application system has many advantages compared with ordinary chiller plus fan coil system: [0003] Environmental protection and pollution-free; high efficiency and energy saving, no matter in winter or summer, the energy utilization efficiency is much higher than other forms of heating or cooling air-conditioning systems; stable and safe operation; more comfortable, no blowing feeling in the room, no noise influence, and the indoor space temperature is uniform ; More beautiful, does not take up any space in the room. Capillary radiation air conditioning application system is widely used in high-end villas, apartments, clubs and other places. [0004] At present, the capillary radiant ...

AI Technical Summary

Problems solved by technology

[0004] At present, the capillary radiant air-conditioning system mainly provides cold and hot water to the terminal capillary network by ordinary cold water heat pump units to meet the needs of cooling or heating of the indoor environment. Ordinary cold and hot water units are designed according to the national standard of 7 ℃ cold water and 45 ℃ hot water And match the various components and settings of the unit. When using a capillary radiant air conditioning system that requires a large difference in water temperature, it is easy to cause unreasonable matching of the various components and settings of the unit, and the energy-saving advantages of the capillary radiant air conditioning system cannot be exerted. The heating effect is not ideal, the use environment range is narrowed, and there are hidden dangers such as indoor condensation and other hidden dangers when restarting after a power failure
