Abstract

The invention discloses a dual-working condition heat pump cold hot water machine unit of a parallel evaporator. The machine unit compresses a circulation loop consisting of a compressor, a condenser, an evaporator and a throttle valve, wherein the evaporator comprises a first evaporator and a second evaporator that are connected with the compressor and the condenser in parallel; the throttle valve comprises a first throttle valve and a second throttle valve, the first throttle valve is arranged between the first evaporator and the second evaporator, the second throttle valve is arranged between the second evaporator and the condenser, and the circulation loop is controlled by the first and the second throttle valves. As the two evaporators are connected in parallel and the flow rate and pressure of the two evaporators are controlled and regulated by the throttle valves between the evaporators to realize the supply of refrigerating water with different temperatures, the machine unit has the advantages of effectively improving the stability of exergy loss coefficient, realizing the simplification of a pipeline system and simultaneously being applicable to an individual independent cold hot source system.

Description

technical field [0001] The invention relates to an energy-saving central air conditioner, in particular to a parallel-connected evaporator dual-working-condition heat pump cold and hot water unit. Background technique [0002] At present, the radiation fresh air system is being widely used. Since radiation and fresh air require refrigerant water at different temperatures, the existing method generally uses a plate heat exchanger to prepare high-temperature refrigerant water. The plate heat exchanger is composed of a series of corrugated A new type of high-efficiency heat exchanger formed by stacking metal sheets with different shapes. Thin rectangular channels are formed between various sheets, and heat is exchanged through half sheets. Since the use of plate heat exchangers is easy to increase the exergy loss coefficient and the piping system becomes very complicated, it is not suitable for household independent cold and heat source systems. [0003] The existing way of pr...
