Heat source combined cycle heat pump building heating, ventilation and air conditioning (HVAC) system

Abstract

The invention discloses a heat source combined cycle heat pump building heating, ventilation and air conditioning (HVAC) system which comprises a multi-source heat pump unit, the multi-source heat pump unit comprises a compressor, the side surface of the compressor is connected with a four-way reversing valve, a gas-liquid separator is arranged on the lower portion of the four-way reversing valve, the gas-liquid separator communicates with the compressor, the side surface of the four-way reversing valve is connected with a first water source heat exchanger, a second water source heat exchanger and a finned heat exchanger, the second water source heat exchanger is connected with the finned heat exchanger through a pipeline, and the output end of the first water source heat exchanger is connected with an air conditioner water tank. When the air temperature is low, the finned heat exchanger is not adopted for heating, if the air temperature is not low, auxiliary heating can be achieved at the same time, and the heat exchange energy efficiency is improved; and a mounting frame is arranged in an HVAC device, a mounting groove is formed in the mounting frame, and a medium pipe is of a U-shaped structure and is arranged in a snake-shaped structure, so that the heat release time of the medium pipe is prolonged.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air-conditioning systems, and more specifically relates to a heat source combined cycle heat pump building heating, ventilating and air-conditioning system. Background technique [0002] HVAC (Heating, Ventilation and Air Conditioning, referred to as HVAC) refers to the system or related equipment responsible for heating, ventilation and air conditioning in the room or in the car. The design of HVAC system is applied to thermodynamics, fluid mechanics and fluid machinery, which is an important sub-discipline in the field of mechanical engineering. Sometimes R is added to the abbreviation HVAC, which stands for Refrigeration, and the abbreviation becomes HVAC&R or HVACR, or R is added to the abbreviation, and V representing ventilation is subtracted, and the abbreviation becomes HACR. The HVAC system can control the temperature and humidity of the air and improve indoor comfort. I...

Problems solved by technology

[0004] The purpose of the present invention is to provide a heat source combined cycle heat pump building HVAC system, which solves the problem that the existing HVAC system in the prior art can use various heat sources such as gas and solar lamps for heating, but it is easy to cause problems during use. Heat loss, and when the air conditioner is in use, the short-term circulation of its medium pipe will easily lead to the problem of excessive heat concentration and high temperature
