Environmental control multi-connected energy unit

Abstract

The invention discloses an environment control multi-connected energy unit. The environment control multi-connected energy unit comprises an outdoor heat exchange part, an indoor heat exchange part, a compressor, a throttling mechanism and a four-way reversing valve, the indoor heat exchange part is provided with a plurality of heat exchange tail ends in parallel, the heat exchange tail ends can achieve heat exchange between refrigerants and air or water, each heat exchange tail end comprises a fresh air tail end, an indoor cold and heat source tail end and a hot water tail end, the hot water tail ends can be connected with the outdoor heat exchange part in parallel or in series through pipelines, when the hot water tail ends are connected with the outdoor heat exchange part in parallel or in series, and heat recovery of the fresh air tail ends or the indoor cold and heat source tail ends can be achieved through the circulating refrigerants; and valves are arranged at the connecting positions of the four-way reversing valve, the compressor, a gas-liquid separator, the outdoor heat exchange part and the indoor heat exchange part with the pipelines. The unit can provide cold and heat for the indoor environment, has multiple functions of meeting the domestic hot water requirement and the like, has an efficient heat recovery function, and improves the energy efficiency of the unit.

Description

technical field [0001] The invention relates to the technical field of energy units, in particular to an environment-controlled multi-connected energy unit. Background technique [0002] With the progress of society and the improvement of people's living standards, people's requirements for the quality of the indoor environment are constantly improving. In addition to the basic cooling / heating needs, they also need fresh air supply, as well as the needs of hot water for kitchen cleaning and hot water for bathing in daily life. . In addition to these needs, users' personalized requirements are constantly improving, and the traditional centralized supply mode of large systems cannot meet users' personalized settings and needs. At the same time, with the advancement of building energy conservation work, building energy consumption continues to decrease, and the energy demand for single households is greatly reduced. The flexibility of centralized supply of traditional large sy...

Problems solved by technology

In addition to these needs, users' personalized requirements continue to increase, and the traditional centralized supply model for large systems cannot meet users' personalized settings and needs.

At the same time, with the advancement of building energy conservation work, building energy consumption continues to decrease, and the energy demand for single households is greatly reduced. The flexibility of centralized supply of traditional large systems cannot meet the needs of various users. With the reduction of the total amount and the increase of household demand Under such circumstances, there is an increasing demand for centralized energy devices for household use. At present, the cooling / heating, fresh air and hot water for each household need to be provided by about 3 sets of equipment, which increases the land occupation and space, and wastes the building area.
