Problems solved by technology

When the air source heat pump unit is cooling in summer, the cooling energy efficiency ratio COPc of the unit is much lower than that of the water-cooled unit, and the cooling energy efficiency ratio of the unit is lower than the COPc under extreme high temperature conditions, and there is frosting on the surface of the evaporator when heating in winter. Frosting on the surface of the evaporator reduces the heating energy efficiency ratio of the air source heat pump to COPh. In order to eliminate the frost layer on the surface of the evaporator, it is necessary to obtain heat from the hot water produced or from the room, resulting in discontinuous heating and affecting the indoor temperature. comfort
In addition, the air source heat exchanger has a low heat transfer coefficient, large volume, and many consumables, which not only increases the initial investment of the equipment, but also puts forward higher requirements on the operating conditions such as the placement space of the unit, which limits the use of the air source heat pump unit
[0004] The use of evaporative condensers can greatly improve the cooling energy efficiency ratio COPc of the unit. At present, it has been proposed as follows figure 2 The scheme of the evaporative cooling unit shown, but this scheme can only realize cooling, and it is difficult to realize heating in winter

Abstract

The invention discloses a solution-spraying type air-conditioner heat pump unit, belonging to the field of refrigerating air-conditioning equipment. The solution-spraying type air-conditioner heat pump unit is technically characterized in that with the adoption of the solution spraying, the unit diffuses condensation heat to the environment in summer and takes heat from the outdoor air environment in winter; and the solution is regenerated by the using of exhausted gas of the compressor or hot water manufactured by the unit. Compared with an air source heat pump unit, the solution-spraying type air-conditioner heat pump unit has the obvious characteristics that the refrigeration efficiency is high, the continuous heating operation can be realized without defrosting in winter and the heating efficiency is high, and in addition, the structure of the unit is compact and the early-investment of the equipment is low.

Description

technical field [0001] The invention relates to a solution spraying type air conditioner heat pump unit, which uses solution spraying to realize that the unit emits condensation heat to the environment in summer and obtains heat from ambient air in winter, belonging to the field of refrigeration and air conditioning equipment. Background technique [0002] With the rapid development of social economy and the improvement of people's living standards, people's pursuit of quality of life is increasing. The energy consumption of building air-conditioning occupies a large share in the total energy consumption. According to statistics, the annual power consumption of central air-conditioning is about It accounts for about 60% of the total electricity consumption of buildings. Therefore, the energy saving of the air conditioning system is of great significance. [0003] figure 1 The shown air source heat pump unit is a commonly used air conditioning and heating device. When the ...
