Air source heat pump device for simultaneously producing water and air

Abstract

The invention discloses an air source heat pump device for simultaneously producing water and air. The device comprises a fresh air refrigerant circulating loop and a radiating refrigerant circulating loop, wherein the fresh air refrigerant circulating loop comprises a first compressor, a first four-way valve, a first outdoor heat exchanger, a first refrigerant flow direction control device, a first electromagnetic valve, a second electromagnetic valve, a fresh air heat exchanger and a third electromagnetic valve which are connected in turn through a pipeline; and the radiating refrigerant circulating loop comprises a second compressor, a second four-way valve, a second outdoor heat exchanger, a second refrigerant flow rate control device, a second refrigerant flow rate adjuster, a ninth electromagnetic valve, a radiating coolant heat exchanger, a first refrigerant flow rate adjuster and a sixth electromagnetic valve which are connected in turn through a pipeline. Through the device, the water of certain temperature and the air of certain temperature can be simultaneously produced, and the flow rates of the refrigerant in the two loops can be timely adjusted according to the variation of air load and humidity load, so that adjustable load is realized, and the device is particularly suitable for a radiating tail-end heat ventilation and air conditioning system.

Description

Air source heat pump device for producing water and air at the same time technical field The invention relates to the technical field of an air source heat pump system for HVAC technology, in particular to an air source heat pump device for simultaneously producing water and air. Background technique The radiation heat exchange between the human body and the surrounding cold or hot surfaces is one of the important factors affecting the human body's cold and heat sensation. In summer, the indoor air temperature is appropriately increased and the average wall radiant temperature is reduced; in winter, the indoor air temperature is appropriately reduced and the wall average temperature is increased. Radiation temperature can make people have a more satisfactory thermal feeling, and can achieve a certain energy-saving effect. At present, the air conditioning system with radiant terminal cooling (heating) combined with fresh air treatment is gradually being researched and appli...

Problems solved by technology

In order to meet the needs of users for these two temperatures, the current engineering methods are as follows: First, install two sets of heat pump units to bear the radiation and fresh air loads respectively. different loads, it is difficult to achieve integrated control of the two units

The second is to use a set of units to first produce refrigerant water of one temperature, and then use the refrigerant water to produce air and circulating water at the required temperature. Although this method can be adjusted according to the load of fresh air and radiation, there are secondary Heat exchange increases energy loss
