The air conditioning subsystem is connected to the waterway subsystem. Specifically, the air conditioning subsystem includes: compressor 1, condenser 2, throttle valve 3 and heat exchanger 7. The compressor 1, the condenser 2, the throttle valve 3 and the heat exchanger 7 are connected in sequence through pipelines. The waterway subsystem comprises: a heat exchanger 7, a water pump 9 and a mattress 10. The heat exchanger 7, the water pump 9 and the mattress 10 are connected in sequence through pipelines. The air-conditioning subsystem and the water path subsystem are mutually connected through a heat exchanger 7 and carry out heat exchange. The air conditioning subsystem also contains an evaporator 4. The evaporator 4 is connected to the air conditioning subsystem by piping and is connected in parallel with the heat exchanger 7. The air conditioning subsystem further comprises a first control valve 6 for controlling the heat exchanger 7 and a second control valve 5 for controlling the evaporator 4.
As a preferred embodiment, the waterway subsystem further comprises a heater 8. The heater 8 is connected to the water circuit subsystem by a pipeline.
Specifically, a first end of the compressor 1 is connected to a first end of the condenser 2 through a pipe. A second end of the condenser 2 is connected to a first end of a throttle valve 3. The second end of the throttle valve 3 is connected by a line to a first end of the heat exchanger 7 and the evaporator 4, respectively. A second end of the heat exchanger 7 is connected to a first end of the first control valve 6 by a pipe. A second end of the first control valve 6 is connected to a second end of the compressor 1 by a pipe. A second end of the evaporator 4 is connected to a first end of a second control valve 5 by a pipe. A second end of the second control valve 5 is connected to a second end of the compressor 1 by a pipe. The third end of the heat exchanger 7 is connected to the first end of the heater 8 through a pipeline. A second end of the heater 8 is connected to a first end of a water pump 9. The second end of the water pump 9 is connected to the first end of the mattress 10. The second end of the mattress 10 is connected to the fourth end of the heat exchanger 7.
Preferably, the compressor 1 is an electric compressor 1. The heat exchanger 7 is a plate heat exchanger. The heater 8 is a PTC heater, specifically a dc PTC heater. The working medium in the air-conditioning subsystem is one of R134a, R1234yf, R22 and R410. Further, the working medium in the waterway subsystem is water or glycol solution. The mattress 10 may be laid on a seat or a bed, and a person may directly contact the mattress 10, so that the bed may be warmed alone in winter, and cooling enjoyment may be provided in summer. The mattress 10 is connected to the waterway subsystem by a hose that can be removed to receive the mattress 10.
In a preferred embodiment, the vehicle-mounted temperature control system further includes a temperature sensor for detecting an ambient temperature. The vehicle-mounted temperature control system performs mode selection according to the temperature detected by the temperature sensor.
The operation of an onboard temperature control system of the present application is described below.
As shown in fig. 2, the mattress 10 is heated by an air-conditioning heat pump. Specifically, the compressor 1 is operated, the second control valve 5, and the first control valve 6 are opened. The refrigerant of over 50 ℃ is brought into the plate heat exchanger 7. Heat exchange between the refrigerant and the aqueous solution occurs, and the heated aqueous solution flows through the heater 8 and enters the mat 10 in the direction of the arrow. The power of the waterway subsystem comes from the operation of the water pump 9. At the moment, the mattress 10 is filled with heat flow, and the proper temperature of the quilt can be ensured when people have a rest. The working mode can well ensure the body temperature of personnel on the premise of not heating the whole cabin, and can ensure the same sleeping time and consume less electric energy due to the low heat loss of the aqueous solution. The heat pump heating system can continuously work in the environment of minus 10 ℃ at the lowest energy.
As shown in fig. 3, in order to quickly raise the temperature of the mat 10 when the temperature is low, the heater 8 is also turned on in addition to fig. 2. When the temperature of the aqueous solution in the waterway subsystem reaches a preset temperature, the heater 8 can be turned off, and the working cycle of fig. 2 is adopted to maintain the temperature of the mattress 10.
The application discloses on-vehicle temperature control system can support and heat the cushion alone, heats the cabin alone and both heat. If the user wants to heat the cabin, the second control valve 5 is opened so that the evaporator 4 serves as a heating unit, the blower fan drives the air flow in the vehicle, and the air is heated after passing through the evaporator 4, thereby gradually heating the interior of the vehicle. This first control valve 6 is closed.
When the vehicle is in the environment below-10 ℃, the heat pump working mode is not adopted for working. As shown in fig. 4, the heat pump air conditioner does not participate in the operation. Both the first control valve 6 and the second control valve 5 are closed and the compressor 1 is not operated. The whole waterway subsystem is driven by a water pump 9, the heater 8 heats the water solution to a set temperature, the water solution flows into the mattress 10 along an arrow, and the water solution returns to the heater 8 through the heat exchanger 7 to be continuously heated.
When the vehicle needs cooling, as shown in fig. 5, the vehicle cabin is cooled. At this time, the compressor 1 is operated, the first control valve 6 is closed, and the refrigerant passes through the condenser 2, is throttled, enters the evaporator 4, and returns to the compressor 1. At this time, the hot air is cooled after passing through the evaporator 4, thereby lowering the ambient temperature in the vehicle. At this time, the waterway subsystem is completely out of operation.
Fig. 6 is a schematic view showing the cooling of the mattress 10 alone, in which the second control valve 5 is closed and the first control valve 6 is opened.
Fig. 7 is a schematic view showing the simultaneous cooling of the mattress 10 and the vehicle cabin, in which the first control valve 6 and the second control valve 5 are both open.
