Multifunctional building integrated cooling and heating device

Abstract

The invention belongs to the field of heating and ventilating devices for buildings and particularly relates to a multifunctional integrated cooling and heating device for a building. The multifunctional integrated cooling and heating device comprises a heat pump air conditioning unit (1), an indoor heat radiating assembly (2) and an indoor unit (3), wherein the indoor heat radiating assembly (2) is connected in series with the indoor unit (3); a main liquid pipe transmission port of the heat pump air conditioning unit (1) is connected with a transmission port of the indoor unit (3); a refrigerant return steam pipe transmission port of the heat pump air conditioning unit (1) is connected with a transmission port of the indoor heat radiating assembly (2); a port of the indoor heat radiating assembly (2) is connected in parallel with a unit protecting element (4); and the heat pump air conditioning unit (1) adopts a heat pump unit, an air conditioning unit, a fixed-frequency unit, a variable-frequency unit or a multistage variable-frequency unit. The multifunctional integrated cooling and heating device is large in heat radiating area, uniform in heat radiation, low in energy consumption and high in cooling and heating efficiencies and is not easy to dew.

Description

technical field [0001] The invention belongs to the field of building heating and ventilation devices, in particular to a multifunctional building integrated cooling and heating device. Background technique [0002] Air conditioning, or air conditioner, refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in a building or structure by artificial means. At present, household air conditioners basically adopt the external unit-inner unit method, and the heat or cooling provided by the external unit is mainly transmitted by the internal unit through the fan. Not only the thermal efficiency is poor, but also the cold (hot) wind is blown directly, which has low efficiency and a very physical feeling. uncomfortable. [0003] Existing building energy storage air conditioners bury metal capillary tubes in the ground or walls. During cooling, condensation will be generated on the ground and walls to p...

AI Technical Summary

Problems solved by technology

Since the buried metal capillary is fixed, the phase change of the refrigerant cannot be adjusted variable, which affects the normal operation of the air conditioning unit (high temperature or liquid machine)
