Embodiment Construction

[0034] The present invention will be described in detail below with reference to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0035] In this embodiment, the air-conditioning system mainly continues to use the existing product HVAC assembly (with evaporator temperature sensor) and condenser assembly (which is more practical for non-newly developed hybrid vehicles, which reduces the cost of HVAC mold opening and saves The newly developed cost of the condenser), high-voltage electric heater assembly, electronic water pump assembly, three-way valve (or two 2-way valves), outdoor temperature sensor, indoor temperature sensor, high-pressure pressure sensor, low-pressure pressure sensor, Composed of air conditioning control module and air conditioning control panel.

[0036] The high-voltage electric heater assembly can heat the coolant in the engine mode and the electric vehicle mode. The three-way valve (or two...

Abstract

The invention relates to a hybrid power car air conditioning system and a control method thereof. The hybrid power car air conditioning system comprises an electric compressor, a condenser, a high voltage electric heater, an HVAC (heating ventilation and air conditioning) assembly and a power source, wherein the electric compressor is connected with the condenser, the condenser is connected with the HVAC assembly so as to form a first loop circuit, the power source is connected with the high voltage electric heater, and the high voltage electric heater is connected with the HVAC assembly so as to form a second loop circuit. The hybrid power car air conditioning system and the control method thereof save cost, simultaneously achieve fast cooling, fast heating and intelligent control of the compressor well, and thereby meet comfort requirements of passengers.

Description

technical field [0001] The invention relates to a hybrid electric vehicle air conditioner, in particular to a hybrid electric vehicle air conditioning system and a control method thereof. Background technique [0002] With the depletion of energy and the seriousness of environmental pollution year by year, countries all over the world have higher and higher requirements for energy conservation and environmental protection. Traditional gasoline engine vehicles are gradually replaced by hybrid and pure electric vehicles. However, air conditioning systems are an indispensable part of vehicles. It is also facing new challenges. The traditional car air conditioner driven by the engine belt cannot be used in hybrid and electric vehicles. At the same time, it is impossible to apply the traditional air conditioning system to new energy vehicles. The first challenge is the mechanical compressor. Since new energy vehicles need to add an electric mode, so in the electric mode, there is...
