Because there are many differences in the common room of structure and material and land of boats and ships, so boats and ships also have a lot of differences with air-conditioning with general domestic air conditioning.Boats and ships can utilize its distinctive environmental advantage with air-conditioning---and seawater because seawater has stronger corrosivity, requires air-conditioning to possess antiseptic power as the heat exchange agent of cooling or thermo-compression evaporation.Compressor is commonly referred to as " heat pump " being used for the process of heating.
Compression-type refrigeration is a refrigeration plant the most frequently used in the air-conditioning system, and compression-type refrigeration mainly is made up of four kinds of refrigeration parts, and they are compressor, condenser, throttle expansion valve and evaporimeter.Its principle is to utilize the characteristic of the evaporation heat absorption of cold-producing medium, condensation heat release to reach the refrigeration purpose, make just that cold-producing medium compresses in equipment such as compressor, condenser, throttle expansion valve and evaporimeter, heat release, throttling, four main thermal processions of heat absorption, finish kind of refrigeration cycle.In addition, adopt electrothermal tube, hot water, steam to heat usually, but efficient is lower.
Summary of the invention
Purpose of the present invention provides a kind of and utilizes a compressor not change the air conditioner for control cabin of vessel that freezes respectively and heat under the prerequisite of expansion valve refrigerant flow direction, and this air-conditioning can utilize that compressor freezes, the auxilliary heating of heat pump electricity.
For achieving the above object, the present invention takes following design:
A kind of air conditioner for control cabin of vessel, comprise compressor, the compressor pressure controller, cross valve, condenser, filter, throttle expansion valve, be provided with the evaporimeter of electric heater and the closed-loop path that connects by pipeline by above-mentioned parts, at described condenser, one bridge valve is set between throttle expansion valve and the evaporimeter, described bridge valve is to be formed by connecting according to the method for attachment pipeline of bridge circuit in the same way by four check valves, wherein the back is in parallel again for four per two series aiding connections of check valve, two ends are connected with the throttle expansion valve closed-loop path respectively, between the check valve of two series connection pipeline are set all and are connected with evaporimeter with condenser respectively.
One fluid reservoir that is used for store refrigerant is set between described bridge valve and throttle expansion valve.
Described compressor is provided with can transfer magnetic valve, and described compressor is connected with refrigeration energy pressure regulation force controller, heats energy pressure regulation force controller, high pressure gauge and low-pressure meter.
One oil eliminator is set between described compressor and the cross valve, is used to separate cold-producing medium and machine oil.
The water inlet of described condenser is provided with hydraulic controller, and described hydraulic controller comprises measuring instrument and seawater gas-liquid bottle, and described measuring instrument is connected the top of seawater gas-liquid bottle, and the bottom of described seawater gas-liquid bottle is communicated with the seawater of condenser inlet.
The present invention has the following advantages:
1, the ingenious pipeline that is applied to of the bridge valve of the present invention principle of utilizing the circuit bridge circuit connects, under the constant situation of original device, unidirectional cooling line can antiport becomes and heats pipeline, compressor is used as heat pump, save cost, heating efficiency obviously improves with respect to the existing electrothermal tube efficiency of heating surface, and is energy-efficient.
2, the present invention is provided with the water pressure controller at the water inlet of condenser, and the pressure by seawater gas-liquid bottle and tester control seawater makes the contact position of instrument and seawater be sealed by air insulated, prevents the corrosion of seawater to instrument; In addition, utilize the low characteristics of seawater freezing point, make the running continuously of equipment, exempt frost control to reach to heat.
