Movable-type heat pump device for partial heating/refrigerating

Abstract

The invention discloses a movable-type heat pump device for heating / refrigerating a specific area of a space. When heating is required, the device pumps middle-temperature air from the space to a condenser end of a heat pump to be heated, and the required heated air is discharged to the specific area directionally; meanwhile, the middle-temperature air is pumped from the space to a main evaporator, after the heat in the middle-temperature air is absorbed, the air is discharged to the farther part of the space; the device is also provided with a secondary evaporator for low-temperature refrigeration, such as ice making; because the heat supply COP (coefficient of performance) value of the heat pump is greater than 1, under the same heat supply amount condition, compared with an electric heater, the device has the advantage that the electricity energy consumption is lowered obviously; when the function of the secondary evaporator is activated for making ice, the device can effectively utilize the cold amount at the secondary evaporator end, refrigeration or ice making is carried out at the same time during heating, the utilization rate of energy sources and devices is improved; when refrigerating is required, an air opening of the evaporator end directly faces a refrigerating area for supplying cold air, and an effect of dehumidification is achieved also. The device does not need a reversing valve, is a heating / refrigerating device with a new concept, is electricity-saving and is low in operation cost.

Description

technical field [0001] The invention relates to a heat pump device, in particular to a movable heat pump device for local heating / cooling. Background technique [0002] Ordinary electric heaters simply convert electric energy directly into heat energy for heating, while centralized hot water heating consumes a lot of heat energy in long pipelines, and the water temperature is completely controlled by the heating company and cannot be adjusted according to individual needs. In contrast, a heat pump is a heating device with an energy efficiency ratio greater than 1, which has a significant energy-saving effect. In addition, the device can increase the ice-making function according to the needs, make full use of the cooling capacity at the evaporator end, and greatly improve the energy utilization rate. In summer, the air outlet at the end of the evaporator is directly sent to the cooling area to send cold air, which saves the reversing valve device and has a certain dehumidif...
