Problems solved by technology
[0009] Even when operating under pure refrigeration or heat pump conditions, most of the time the traditional air conditioning system deviates from the design conditions. When the air conditioner is just started, the indoor temperature drops slowly, and when the indoor temperature stabilizes, The outdoor temperature may change with time, and the working fluid filling volume of the traditional air conditioner cannot be adjusted accurately, which means that the working fluid filling volume of the traditional air conditioning system is not in the best state most of the time

Embodiment Construction
[0025] figure 1 It is a schematic diagram of embodiment 1—a simple air-conditioning and refrigeration system, including a compressor 1, a condenser (outdoor unit) 3, an expansion valve 4, an evaporator (indoor unit) 5, and a working fluid circulation circuit composed of pipelines connected to the above-mentioned mechanisms in sequence . An energy efficiency booster 6 is connected to the working medium circulation circuit, and the energy efficiency booster is composed of a variable volume container 61 and an actuator 62 for changing the volume of the container. As a preferred embodiment, the connection position between the variable volume container 61 and the working medium circulation circuit is set at the circulation pipeline at the outlet of the compressor 1, because the circulating working medium there has high pressure, high density and variable volume A relatively small change in the volume of the container 61 can have a relatively large impact on the average density of ...

The invention belongs to the technical field of refrigeration and heating, in particular to a vapor compression air-conditioning system equipped with an energy efficiency booster. The energy efficiency booster is connected to the working fluid circulation loop of the system, and the energy efficiency booster includes a variable volume container and an actuator for changing the volume of the container, and the connection position between the variable volume container and the working fluid circulation loop It is arranged at the circulating pipe at the outlet of the compressor. The present invention solves the problem existing in the prior art that the system is difficult to work in the state of optimal energy efficiency ratio (EER or COP) due to the fixed average density of the working fluid. It is an air conditioner The system provides a new performance adjustment method, which can significantly improve the energy efficiency ratio of the air conditioning system and significantly improve the operating performance of the air conditioning system.
Description
technical field [0001] The invention belongs to the technical field of refrigeration and heating, in particular to a vapor compression heat pump air-conditioning system equipped with an energy efficiency booster. Background technique [0002] Vapor compression air-conditioning systems include air-conditioning refrigeration-heat pump systems, simple air-conditioning refrigeration systems, simple heat pump systems, and heat pump water heater systems. Compression increases the temperature and releases heat to high temperature media (such as outdoor or indoor air). In order to obtain the most economical and efficient operation effect, the condensation temperature of the working fluid should be higher than the temperature of the high-temperature medium by a minimum reasonable temperature difference ΔTk, and the evaporation temperature of the working fluid should be lower than the temperature of the low-temperature medium by a minimum reasonable temperature difference ΔTe.
